CrossFit Grip Buyer's Guide: How to Choose the Right Pull-Up Grips
The wrong grips make themselves known halfway through a pull-up workout. Your palm bunches, the bar starts sliding, and every rep becomes a negotiation with a hot spot that is about to tear. This guide is built for athletes who need their gear to hold up when the workout is not backing down.
What CrossFit Grips Actually Need to Do
A good pair of pull-up grips has three basic jobs: create reliable contact with the bar, protect the high-friction areas of your palms, and stay comfortable enough that you are not thinking about your gear halfway through the workout.
Create a predictable connection between your hand and the pull-up bar.
Reduce direct friction across the palm during high-repetition gymnastics.
Good grips should help your movement instead of becoming the thing you notice.
That sounds simple until sweat, chalk, different rig surfaces, fatigue, hand size, skill level, and gymnastics volume all enter the equation.
A grip that feels fine for five strict pull-ups can behave completely differently during 75 chest-to-bar pull-ups after your forearms are already cooked.
Buy for the work you actually do most often, while leaving enough room for the athlete you are becoming.
Start With Your Athlete Level
At RBST Gear Co., we do not believe every athlete needs the most aggressive grip available. A beginner working toward consistent pull-ups has different needs than a competitive athlete trying to hold together a massive unbroken chest-to-bar set.
That is one reason RBST offers different grip platforms instead of forcing every athlete into one design.
IRON CLAW™
The RBST Iron Claw uses a resilient silicone front and reinforced backing to create a comfortable, controlled connection to the bar.
- Great for beginners and intermediate athletes
- Comfortable for everyday CrossFit training
- Fingerless design
- Strong grip without an overly aggressive locked-in feeling
- Excellent for pull-ups, toes-to-bar and chest-to-bar
- Minimal break-in time
IRON X™
The RBST Iron X combines a natural rubber front with reinforced Kevlar backing for athletes who want a thinner, more aggressive connection during demanding gymnastics work.
- Built for intermediate to advanced athletes
- Designed for high-volume gymnastics
- Natural rubber gripping surface
- Reinforced Kevlar backing
- Aggressive locked-in feel
- Built for competition and large sets

Start With Your Bar and Training Volume
Before comparing grip materials, look at the bars you actually train on. This matters more than most athletes realize.
Powder-Coated Bars
Powder-coated pull-up bars can create substantial friction, particularly when the surface is rough, heavily textured, or worn from years of use. That additional friction may feel secure, but it can also increase the amount of force transferred into your palm and your grips.
Smooth Steel Bars
Smooth steel bars often feel faster and less abrasive but can become much more challenging once sweat builds. The right grip needs to maintain predictable contact without forcing you to squeeze the bar to death.
Cerakote and Other Coated Bars
Cerakote and similar surfaces often fall somewhere between a rough powder-coated bar and smooth steel. Wear, cleaning, chalk buildup, humidity, and the number of athletes using the rig can all change the feel.
If you train at multiple gyms, test your grips on more than one rig before competition day. What feels incredible on your home rig may feel different on a competition bar.
Training Volume Changes What You Need
Occasional pull-ups and high-volume competition gymnastics are not the same demand.
If your workouts include occasional sets of pull-ups, a comfortable, forgiving grip may make the most sense. This is where Iron Claw fits extremely well.
If you routinely train chest-to-bar, toes-to-bar, bar muscle-ups, large unbroken sets, or competition-style gymnastics volume, durability, responsiveness and palm coverage become much more important. Iron X was built specifically around those demands.
High volume exposes weak gear fast.
The higher your gymnastics volume becomes, the more important sizing, material, hand position and grip consistency become.
Choose a Grip Material That Matches Your Training
Grip material changes the relationship between your hand and the bar. It affects feedback, friction, grip aggression, thickness and how the grip behaves when sweat or chalk enters the equation.
Silicone
Silicone can create a sticky, controlled connection without requiring an extremely thick grip. RBST uses a resilient silicone surface on Iron Claw , making it a strong option for athletes who value comfort, consistency and confidence during everyday gymnastics training.
Natural Rubber
Natural rubber can deliver a more aggressive bite and close connection with the bar. RBST uses natural rubber on Iron X , combined with reinforced Kevlar backing for athletes pushing higher-volume gymnastics.
Leather and Suede-Style Materials
Leather-style grips offer a more traditional gymnastics feel. Many athletes like the way the material changes and molds with use, although these grips can behave differently depending on chalk, wear and moisture.
Carbon-Style Materials
Carbon-style grips remain popular because they can offer a thin, responsive feel. RBST also offers additional grip options beyond Iron Claw and Iron X in the pull-up grips collection , allowing athletes to choose based on their preferred feel and training style.
Thicker Does Not Automatically Mean Better
A thick grip may provide more material between your palm and the bar, but more material can also reduce feedback.
Athletes with smaller hands may especially notice this. If too much material sits between your palm and the rig, it can effectively increase the diameter of the bar and make it harder to establish a strong hook.
A thinner grip usually gives you more bar feedback and quicker transitions. The trade-off is that the material still needs enough strength to survive the volume you are putting through it.
Do not automatically blame grip thickness when your hands tear. Excessive squeezing, poor placement, thick calluses and sudden jumps in gymnastics volume can still destroy hands while wearing premium grips.
Finger-Hole vs. Fingerless Grips
Finger-Hole Grips
Traditional finger-hole grips stay connected through the fingers and can feel familiar to athletes coming from gymnastics-style equipment. Some athletes appreciate having the grip positioned consistently throughout the workout.
The downside is that finger holes can slow transitions and may feel restrictive if the fit is not right.
Fingerless Grips
Fingerless grips allow athletes to move quickly between gymnastics, a barbell, dumbbells, burpees and other movements without threading their fingers through the grip every time.
Both RBST Iron Claw and Iron X use a fingerless design. This gives athletes greater freedom during dynamic gymnastics and faster transitions during mixed-modality workouts.
The best design is the one you can use under fatigue.
Your gear needs to work when your heart rate is high, your forearms are pumped and the clock does not care that you need another 20 seconds to adjust your grips.
Fit Is Where Most Grip Problems Begin
You can buy an incredible pair of grips and completely ruin their performance by wearing the wrong size.
Do not guess from glove size. Measure your hand according to the sizing instructions for the specific grip you are buying.
With RBST grips, measure from the wrist crease toward the base of the middle finger according to the product sizing guide. If you fall between sizes, avoid automatically sizing down just because you want a tighter-looking fit.
- The wrist closure feels secure without cutting off circulation.
- The grip reaches the area of the palm you are trying to protect.
- The material does not bunch excessively.
- You can create the grip position or fold you prefer on the bar.
- The grip does not rotate excessively around your hand.
- Your wrist and fingers can still move naturally.
If your grip constantly slides down, twists, pinches or leaves the exact same hot spot exposed every workout, check sizing and placement before assuming the material itself is the problem.
Sweaty Hands Need a Full System
Sweat changes grip performance dramatically. Even a great gripping surface can become less predictable when sweat runs from your forearms into your palms.
This is why RBST treats sweat control as part of the grip system rather than an unrelated accessory.
RBST Performance Sweatbands are designed to help reduce moisture reaching the hands during high-output training and can be paired with Iron Claw or Iron X grips.
Chalk: More Is Not Always Better
Chalk absorbs moisture and can improve your connection to certain surfaces, but dumping half the chalk bucket onto your grips is not automatically an upgrade.
Excess chalk can combine with sweat and contamination from the bar to create unpredictable buildup.
Both RBST Iron Claw and Iron X are designed for strong performance with minimal or no chalk depending on the bar condition and athlete preference. Clean grips and a clean bar are the best place to start.

Wrist Support Matters — But Grips Are Not Wrist Wraps
The wrist strap on your grips exists primarily to keep the grip positioned correctly. A structured wrist section may also provide some stability during bar work.
That does not make your pull-up grips a replacement for dedicated wrist wraps.
For heavy cleans, front rack work, jerks, presses or handstand volume, dedicated wrist support may be more appropriate. Browse RBST wrist protection if you want to build a more complete training setup.
Do Not Forget Your Thumbs
Pull-up grips protect your palms during gymnastics, but heavy barbell training creates a completely different type of stress.
Athletes using a hook grip for cleans, snatches and heavy pulling may benefit from keeping RBST Thumb Tape in their gym bag. It is designed to handle sweat, support grip security and tear easily without scissors.
Test New Grips Before Competition Day
Never make your first competition workout the first serious test of your new grips.
Start with short, controlled sessions. Try strict pull-ups. Add kip swings. Move into moderate sets of toes-to-bar or chest-to-bar. Then gradually expose the grip to the type of volume you expect during training or competition.
Pay attention to where heat builds. Minor positioning adjustments can be normal. Sharp pinching, immediate slipping or a new hot spot that appears every time deserves attention.
Competition preparation is about eliminating unknowns. Your grips should be one of the things you already trust.
Take Care of Your Hands and Your Gear
Even excellent grips cannot save you from neglected hand care.
Thick callus ridges create leverage points that can catch and tear during kipping movements. Keep calluses controlled, pay attention to hot spots and avoid dramatically increasing gymnastics volume overnight.
Your grips need care too.
- Remove excess chalk after training.
- Hand wash when sweat and buildup accumulate.
- Use mild soap and water when appropriate.
- Air dry completely.
- Avoid high heat.
- Do not leave wet grips compressed inside a gym bag.
- Store them flat or hanging when possible.
Proper sizing, positioning and maintenance play a major role in grip life. Rough bars, excessive friction and incorrect folding can damage even durable grips over time.

11. Do RBST pull-up grips require chalk?
Iron Claw and Iron X are designed to perform with minimal or no chalk in many situations. Bar condition, cleanliness, humidity and athlete preference still matter. Avoid excessive chalk buildup and follow the instructions for your specific grip model.
12. Which RBST grip is better for sweaty hands?
Both Iron Claw and Iron X are designed for strong bar contact during intense workouts. Athletes who sweat heavily can also pair their grips with RBST Performance Sweatbands to help reduce moisture running into the palms.
13. How should CrossFit grips fit?
Your grip should provide enough palm coverage to protect the areas exposed to friction while still allowing you to create your preferred grip or fold on the bar. It should not be so short that the palm is exposed or so long that excessive material bunches uncontrollably.
14. Should I size down in CrossFit grips?
Do not automatically size down. Measure your hand using the sizing instructions for the specific RBST grip. If you fall between sizes, choosing enough length to create proper palm coverage is generally more important than forcing the smallest possible size.
15. Why are my grips bunching in my palm?
Bunching can be caused by incorrect sizing, grip placement, hand position or using too much material between your palm and the bar. Recheck your sizing and setup before assuming the grip itself is defective.
16. Why do my hands still tear while wearing grips?
Grips reduce direct friction but cannot eliminate every cause of tearing. Thick calluses, excessive grip pressure, poor hand placement, worn bars and sudden increases in gymnastics volume can still lead to torn hands.
17. How do I clean RBST pull-up grips?
Remove excess chalk and buildup, hand wash gently with mild soap and water when needed, and allow your grips to air dry completely. Avoid high heat and do not leave wet grips compressed inside a gym bag.
18. Should I break in new grips before a CrossFit competition?
Yes. Use new grips during controlled training before competition. Test them on strict pull-ups, kip swings and the gymnastics movements you expect to perform so sizing, placement and bar feel are already familiar.
19. Should I wear sweatbands under my CrossFit grips?
Athletes who sweat heavily may find wrist sweatbands helpful because they reduce the amount of moisture traveling from the forearms into the hands. RBST Performance Sweatbands are designed to pair with Iron Claw and Iron X as part of a complete grip setup.
20. Which RBST pull-up grips should I buy?
Choose Iron Claw if you prioritize comfort, control, daily training and a forgiving feel. Choose Iron X if you are an intermediate-to-advanced athlete who wants a thinner, more aggressive grip for high-volume gymnastics and competition. You can also browse the complete RBST Pull-Up Grip Collection .
