New favorite riding shorts

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

I highly recommend these shorts. They are super comfortable. It comes down to the 4-way stretch material. The 4-way stretch allows the best freedom of movement of any shorts I've tried to date. Overall quality of the materials and the stitching is good too.

Well-thought-out features include:

deep zippered pockets
right pocket has a padded cell phone sleeve
sturdy hook and loop velcro waist adjustments
ventilation holes to keep you cool

The inseam on these shorts is a good length too. It comes down right to my knee, perfect for most types of riding. These shorts work well with lower profile knee pads. For a similar short with longer inseam check out the Ion Scrub AMP.

I am 5'11, 185 lbs with 34" waist and the Large fit me perfectly.

Unanswered Question

What's the length of the inseam on these (size small)? Thanks!

Great for Biking

I recently picked these up and they are a solid biking short! I really like the hand on the material - it's moisture wicking, lightweight, breathable, and durable. I've taken a few diggers while wearing these and they still look brand new! The leg openings have plenty of room for knee pads and the two zipper pockets are perfect for a phone and whatever else you like to carry. I'm a 33" waist and went with the large and, after some adjustments with the waist velcro, they fit great!
