They work

  • Familiarity: I've used it several times

The liners work. Either they're heavy on the cushion, or my old ones were well worn. I followed the sizing chart and went with the large for my size 34 waist. The waist band fits fine, but I have large thighs and these are maybe just a little too tight for my overall preference. I feel the XL would fit the legs better, but would most definitely be too big around the waist, But overall I am good with the purchase.

They Tickle My Fancy

Great liners. I owned a pair already that came with my fox shorts and decided to double down so on days of back-to-back riding I wasn't putting on some musty duck butter soaked liners again. These things are comfy, light, breathable and work great with all my shorts. There as close as you can get to a thousand little ferries tickling your dedicates while riding. :-) Highly recommend. I'm a 32 inch waist and got the medium. A

Great Liners

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

I got these for my boyfriend and he says they are great. He has been mountain biking a lot this summer and really needed some liners that would do the job, just like these. He said they do a great job of staying in place and he doesn't have to constantly re-adjust them while he is riding.

Comfortable and well made chamois

Very smooth, no abrasions, seems well stitched. Fits true to size in my opinion.

My Favorite liner!

The best liner out there. Great support, super comfortable, and they don't ride up your quads during your ride. My touch appreciates the EVO chamois and so will yours!

No Riding For the Riders

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Large

Not only do these have amazing comfort with the EVO chamois, but they have great grip on the legs to prevent riding up on the legs. With bigger quads that is always a problem for me with most baselayer shorts, but not these. Love them and can't wait to log some long days on the bike with them this summer.

Cham WOW

  • Familiarity: I've used it several times
  • Fit: True to size

These "cham" are fabulous! The keep your touch comfy on a long ride. They are breathable and light. The elastic bands keep the chamois in place. They fit true to size. I am a size 32 and purchased the medium.

Good price for a great liner

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: M

I usually wear a size 31 or 32 and I grabbed a medium in this liner. The fit is spot on. The leg openings feel perfect and the elastic part is just the right amount of sticky without feeling weird. Prior to these, I had only been riding in the Fox liners that came with the shorts and I am really glad that I made the move up to a nicer pair. You will not be disappointed in these.

Worth it!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: med

I have worn many different chamois', and this one is simple and comfortable. I have a 32 waist, and bought the medium. This pair is nice since it doesn't get super tight in the crotch. I have worn some pairs of chamois that are tight enough to make your goods sore for the rest of the day. Definitely happy with this one, and will probably buy another pair. The cost is very fair considering the comfort. I've spent over 3 hours on the saddle with plenty of climbing, and have been thankful for the forgiving padding of this short.

This is my first cycling short, and I love it. Simple design, very comfortable and flexible. About the size, I bought M and it fits great.
