You’ll love the Flash shorts from Crazy Idea, well, in a flash! The original Skyrunning shorts, you can haul uphill while hauling plenty of gear in the 5 pockets that are situated around the waist. The microfiber inner briefs are coated with Graphene to help with odors that may arise on a hot, sweaty day. They also sport inside-out seams to avoid chafing in your nether regions. The outer is a micro-perforated, water-repellent fabric that both wicks moisture as well as does some work to keep you dry when crashing through dense forests. The hem is laser cut and bonded for a smooth feel that leads to faster runs (we will fact-check this along the way). The Flash shorts from Crazy Idea are the OG of the Skyrunning world and should become a part of your world for so many obvious reasons.

  • 5 pockets on the waistline can carry anything from gels to jackets.
  • Graphene-treated briefs are comfy and won’t smell up your laundry basket.
  • Micro-perforated outer fabric is lightweight and highly breathable.
  • Water repellent finish is a pretty sweet feature to keep you dry on a wet trail.
  • Inside-out stitching in the briefs avoids chafing for more enjoyment on longer runs.

I've had a pair of Flash Shorts for about a year and half and have been loving them! The waistband pockets are versatile and on short to medium length runs, it keeps me from using my running belt or a vest. I can fit gels, keys, a small flask in the back pocket and trash in the waistband. There is also a drawstring around the waist to keep it snug so your accessories don't bounce or fall out of the waist. They are clearly made out of very premium materials that other brands don't quite compare to, and it's a treat to have a pair of Crazy shorts in my quiver.

These are in Euro sizing so go up a size from your usual!

Nice shorts but the sizing runs small. I'm 6', 170lbs. 31 inch waist. Medium wasn't even close. Sending them back for a large. Fingers crossed.
