Comfortable, well-fitted at a reasonable price

Firm leg binding makes these ideal when out of the saddle in climbing.

Great but Run Small

They are a great technical riding short but run on the small size. Suggest trying on before order or going up a size.

comfortable shorts

fit is great. I'm 6"-0", 170 lbs, 31 in waist, 34" inseam, bought a medium. these shorts are very comfortable and fit well. The legs are longer than most of the other brand riding shorts I own, which I also like. put about 70 miles on them over 3 rides, longest of which was ~25 miles.

These are my new favorite shorts.

Comfortable for spending most of the day on the bike, the fit was great and the leg bands are wide enough to prevent them from creeping up.

Third Pair of Obsidian Men's Prisma Shorts

This is my third pair of these shorts (the other pairs were gifts) and I absolutely love them. They say in the cycling world that comfort makes the ride and I have found that after wearing and riding other brands that these fit me perfectly. I'm not a world class athlete I'm just a 55 year old man who rediscovered cycling after a fifteen year hiatus and I'm enjoying heading out on any length of ride wearing my primal gear and leaving the daily grind at the curb.

How to Measure

1. Measure your waist– this measurement should be taken above the hip bones, should run pretty close to the top of your belly button.

2. From this measurement, you should be able to find your correct size.

If you are in-between sizes, weight and height can factor in, but should not be necessary.
