I’m 5’10 172lbs and the shorts fit pretty well. The grippers at the bottom of the shorts are soft yet stay in place. When I first put on the shorts the pad seemed too large, like a cycling short almost, but after one use, they feel fine. My only complaint is the waist feels too tall. I prefer a lower waist and have to pull these up a bit in order for the pad to sit right. Good color(red) and the pockets are large.

Fit is true to size and the 2 pockets are a great addition! The padding is surprisingly comfortable considering the thinner padding. It provides the necessary cushioning however, does not interfere with the run. These are my go to for any training ride or event.

Great for swim/bike/run but the pockets at the back are too big, stuff just jumps all over or drops out

Best triathlon shorts ever. SLS3 is the best fitting tri gear for my frame. German made and durable and they look awesome. I will buy again. Fits as expected according to size chart. I bought XL.

Es un buen producto y da buen resultado al usarlo. No es nada compresivo, para ello habría que ajustar la talla a la baja

I am from a generation who raced in pants with leather chamois. I am tired of these bulky bike shorts with gel and thick 3D/4D padding - buying bike shorts has become a hit and miss affair meanwhile. I wanted something less bulky. These were great from that perspective - my backside is bike seat hardened. I am 83cm waist, 93 hips/backside, 55 upper thigh. I purchased medium but after riding in them once I found them too tight around backside and thigh. In hindsight an L might have been better choice. I like the design, but think the unstitched lycra leg ends may be susceptible to easy tearing.

I recently started doing weekly Wednesday morning 6 am triathlons with a group of friends. After trying a few different brands, these shorts quickly became my go to pair. the fit is great, the pad doesn't feel bulky and they dry quickly. I'll be buying additional pairs for sure.

These shorts are a very good balance of bike and running comfort. They have gone as far as they can with the padding without it feeling like you are wearing a diaper on the run. The important thing they got right is the seam around the inner pad. Some other shorts I tried I had to return because of the big lip on the inner seam absolutely buzz-sawed you in the inner thighs. These have a seam that is completely sealed to the shorts so there is relatively no lip to dig into you. Also, if you are on the border of size, order the smaller. I was right on the border of M and L and the L was way too big. The M is perfect and just the right compression. I have done a couple of run and bike training sessions at 70.3 distance and they were quite comfortable during both. I will be doing some test bricks this week and then will try them in my next race. I got a couple of pair and if all goes as expected through that race, I will order a couple more.

Great shorts with useful pockets. Leg grips are less substantial than on my Saucony shorts but seem to keep the legs in place. Cycle padding looks good but haven't biked with these yet.I have the matching run vest which I also like - both for its comfort but also for the rear pockets which are lacking on most running vestsThe only downside is the colour - I like the appearance but lighter colours would be good for the hotter weather

Fit as expected, but the legs are not as snug as I would like. Material is thin, but works well on the swim and bike. Personally, I like thicker material on the run...I'm a bit older and prefer more compression. No knock against the item, it is good quality and comfortable.

These are great shorts. I have had them for about 2 weeks. I am training for my first triathlon so these are my first pair but they are comfortable, don't ride up at all biking and stay put well for swimming. The pockets in the back are great too. From my research, these seem well priced and I am satisfied with these. Will update if I have any issues. For reference, I am about 5' 6", with a 31-32 waist and a M fits me great. waist is perfect and length are 1-2 inches above the top of myknee.
