These sleeves are awesome! I've worn them probably 100+ times now, including in 2 comps, and they've held up superbly. Not to mention they are relatively inexpensive for competition knee sleeves when compared to some of the more talked-about brands.

The sleeves are easy to put on once you get the method down (I fold the top and bottom of the sleeve over itself, pull it on, then unfold) and seem to be extremely durable. These things are STIFF and give me 100% confidence to squat some heavy ass weight (comp PR is 656lbs, pictured).

For the price you really cannot go wrong. Just go ahead and buy them!

I have had a few different sleeves priced at $100+, they ripped and were poor quality after 6 months. I used the Pioneer sleeves to prep for and compete in a powerlifting meet and they look and feel new still. I hit over 700 with these wizards and they held up amazingly. I bought a pair for my wife and highly recommend these!

and crushed my squats. With only a couple weeks experience in them. Great sleeves. Thx.

Notice good rebound over my SPDs. Perfect fit. 235 lbs 17 calve and 4xl was perfect. Love this brand.

I’ve had them since July of 2023 they worked amazing til somebody stole them didn’t have any issues and they were amazing:

Sizing I wore and XL:
My measurements were:
Calf 17.5
Knee 14.5
Quad 22

Finally bought into getting some sleeves and Heard how stiff pioneer sleeves were and they were the best priced out of the competitors so I got some. Ordered a size up and glad I did. These mofos are tight! Does it make you have a stronger squat yes and no. Knee pain or aches gone. Knees felt like they were wrapped and was able to do a 30-40 minutes squat session with them on. So yes and no . I usually can rep 315 3 times shakey . But with these sleeves I was feeling confident going deep with 315. Love these sleeves. Knees felt the most secure I’ve ever felt them be. Did this video at the end of my workout just for the review.

I received my knee sleeves today and couldn’t wait to test them out—and wow, they did not disappoint! The difference they make is night and day. With the sleeves on, my knees feel incredibly supported, offering fantastic stability during my lifts. They even helped me hit a new personal record today! I’m giving these knee sleeves a well-deserved five-star rating.
One tip: stick to the size chart. I initially struggled to choose the right size and had to exchange for a different one, but the chart was spot-on. For those new to knee sleeves, putting them on can feel tricky. I recommend the “fold-in-half” method: fold the sleeve in half, position it where you want it, then roll it up to fit snugly over your thigh, knee, and calf.
I’ve purchased several items from this brand, and everything has been top-notch. If you’re on the fence about these knee sleeves, trust me—just get them. You won’t regret it!

One of the best and my favorite knee sleeves to wear for squatting. Theyre very stiff and fits me perfectly for which i use for heavier squat days. Price is very good for a stiff knee sleeve, which i highly recommend in general.

I absolutely recommend these sleeves they are game changers I hit a 445lbs squat PR @ 236 lbs body weight at the SPF meet on March 15 2025 I’m on track to hit 500 with these sleeves this year and I’ve never had a better product to help me all I can say is thank you for providing me with quality stuff keep up the great work can’t recommend enough

This is the second item I buy from pioneer. First was a custom belt I bought for Xmas and I was amazed by the quality so for my bday I bought a pair of knee sleeves. They’re just as amazing and well made. However I do believe the sizing chart is slightly off. I measure my calves at 16” and the other at 15 1/2” which puts me in a size XXL. I even messaged pioneer to double check(never got a reply back though). When the sleeves came in, super fast shipping by the way (I live in Canada), I couldn’t wait for my next leg day. Just around at home they were a little hard to get on, and very difficult to get off. Now! When I hit legs they’re next to IMPOSSIBLE to get off! I HIGHLY recommend going up another size because they’re so well made and they help so much! It’s such a shame I don’t use them because once my legs get just a little pump these become too difficult to get off.

Sleeves are very stiff and surprisingly easy to get on/off. 415x4 was easy and my best squat in competitors sleeves is only 468lbs.

These sleeves will be my go to for heavier squat days. Definitely feel a good bounce out of the hole! My calves are 15”, lower quad 20”. First order was two sizes up from the chart, 2XL, too small! Ordered another pair (3XL) and they are perfect. All in all, great value for a high quality sleeve.

These are absolutely the best knee sleeves I have used. Hit a PR the first time using them, squatting 545# the only complaint I have is I had to size up from 2xl to 3xl even going by the size chart. FYI you have to pay shipping a total of 3 times to get them exchanged. Customer service was great but I ended up paying for 2 for the price of one 🙃 would recommend sizing up from chart.

Just got these knee sleeves very stiff compared to the SBD ! You’ll get more bounce from the bottom with these ! I’ve order size 2X and it feels just right with a bit of pressure in my calves and I’m size Large in a SBD ! Becareful in sizing cause they don’t stretch at all good luck

These are my first pair of competition powerlifting style knee sleeves. Previously I have only worn Olympic weightlifting style wraps and sleeves, so the rigidity was something I was not prepared for, so the description is accurate, they are crazy stiff! My calves measured right at 18” so went with 4XL. With some grunting I was able to get them on to the right spot. A lot of pressure around the joint forsure, will have to see what actual training feels like. I was able to get them off relatively easy compared to putting them on. Just rolled them over and that was it.

These things are awesome!! They are tight!! I measured out to an "L" but got an "XL" these are still tight. Glad I emailed them prior to purchasing. They leave marks on my legs but I don't care my quads feels good and weights moving smoothly.

I followed the sizing chart and bought XL for my 15 inch calves. Tough to put on, but impossible to remove. I had to cut them off so I’m really bummed. I folded them in half to put them off and attempted to do the same to remove them. I even used pliers to grab onto the material. Once my feet started going numb I bit the bullet and cut them off.

BEST KNEE SLEEVES!!!
These are tight and squeeze but not painful and not impossible to get on an off like competitors!! Best purchase ever! Immediate PR!

These are THE BEST knee sleeves on the market. Tight like the competitors but they are NOT painful!! They SQUEEZE and they are still difficult to get on and off (that’s a least a workout) but it’s much easier than competitors and doesn’t take a team of people. Once you get it started they will slide off. I messed up my calf muscle with Inzer and these are nothing like that, they don’t pull your muscles . I noticed a lot of comments with the sizing. Be sure to measure and understand that you need to look up tactics for getting knee sleeves on and off. Best trick is to fold them in half for pulling on and off. It shouldn’t be easy! I’m a 180lb female and I have thick legs. 15.5 inch calf, 28 inch thigh. I have a 3XL and they are tight. I immediately got a PR in these! They are fantastic!!

I think they are the best sleeves money can buy, especially if you’re a super heavyweight power lifter I’ve had my pair for close to a year now super durable still the same amount of spring As the first time I used them!!!
