Arc Short

There's a reason you're riding fifteen miles into the wild on a skinny dirt trail, and it's most likely to get away from annoying distractions of modern civilization. Helping you find your happy place without disturbance, the Giro Men's Arc Short opts for a clean, no-nonsense design that's purely focused on unencumbered comfort instead of flashy graphics and gimmicks.

Lightweight, tear-resistant ripstop fabric withstands the rigors of daily jaunts in the hills and rolling forests outside of town. Best of all, it's completely silent, so you can tune-out to the sound of birds chirping and tires rolling over trail impediments. For greater comfort on rainy rides and dewy mornings, the DWR finish repels outside moisture and flinging dirt from soaking through and staining this short.

  • Plot your trail escape in no-nonsense comfort
  • Slides over your padded liner short (not included)
  • Lightweight, durable, silent ripstop fabric
  • DWR finish repels light rain and flinging dirt
  • Adjustable waist tabs for a fine-tuned fit
  • Zippered pocket holds snacks and accessories
  • UPF 50+ ensures protection from harsh UV rays
  • Item #GIRZ324

Meh - not in love

I've used it several times
Runs large
Size Bought

I have a handful of bike shorts from Patagonia, Yeti, REI and these. Of them, these are my least favorite. The material is solid and seems like it will hold up well. It's also pretty stretchy so easy to ride it. The fit is a bit odd - they run bigger than other shorts I have (both bike and non-bike shorts), in terms of waste, hips, and length. They look a bit like shorts from 1996 in that regard. As well, the phone pocket is poorly placed. If you put your phone in it while riding it will restrict your pedal stroke and/or flop around on you. I have other shorts, such as the Patagonia Dirt Craft, which have a much better 3rd pocket design. I got these shorts on sale so it was probably worth it, but I'd recommend looking elsewhere before these.

Nice, basic short

I've used it once or twice and have initial impressions

Nice, basic short that can be used for riding or casual wearing. Belt loops are a plus as velcro adjusters just don't help with keeping shorts in place. Very thin/light weight material will be great during hot weather but prolly won't last if I take a digger or two (I try to stay upright as much as possible). Nice color, good fit (slim not baggy).

Lunch Lap Ripper

I've put it through the wringer
True to size

These shorts are perfect for that quick lap during lunch or right after work. Throw your keys in the zippered pocket and go. They fit true to size, and the length is perfect to keep away any pad gaps.

Underrated Excellence

Giro's an underrated brand in my opinion, I found the ARC short to be excellent in quality and fit, right up there in design with any other brand I've used. Fit on these in the waist was spot-on for me, the length comes to mid-knee but that will vary depending on your inseam. They're just loose enough to move in without feeling baggy. You've got velcro waist adjusters and belt loops to dial in the fit. I found the material to be tough - after some bushwacking through miles of scrub oak they still look like new. They aren't too heavy duty to not breath well though, although I wasn't riding in hot condition I definitely wasn't overheating on the climbs. You've got 2 hand pockets and one zippered hip pocket that I found well placed and plenty big for a phone. 5 stars for these for sure assuming they hold up well - all my other gear from them certainly has!
