Light & Breathable Shorts for the Summer

I've been trying to find a pair of shorts that are extra light, but still have enough pocket space to store keys and gels for long runs, and I finally found them! These shorts barely weigh anything, yet you're still able to fit everything you need for a long trail run in the pockets because of the unique waistband pockets.

Stylish and versatile!

These shorts are so amazing and versatile. They are perfect gear for a morning at Crossfit with so much flexibility and room for squats or deadlifts (plus the style gets a lot of attention from my fellow athletes). They are perfect for a day at the beach or a hike up in the mountains. They also are incredibly comfortable. In the immortal words of Ned Flanders, "feels like I'm wearing nothing at all!"

Great running shorts

The fit is great and it is comfortable to wear. It can hold my iPhone but does bounce a little. The split is high and allows good freedom of movement in intensive runs.

Super light and comfy

These are some of the lightest and comfiest, not to mention the most rad lookin shorts I’ve ever worn. I have some concerns about durability with the super thin fabric, and the delicate stitching but I’m ready to be proven wrong about that. I’ve worn these hiking a few times now and love them

So rad!!

Amazing shorts! I bought these for my boyfriend who is an avid runner. He has been running in worn-out shorts that are 8+ years old, so these have been awesome. He is really stoked about them and they fit perfectly.

only the hardcore will understand

when other hardcore runners interrupt their runs, pause their watches, extract their earbuds to chase you down to ask you “where did you get your fit?” - you know that you are doing something right!

this running gear cannot be beaten, or even matched! Timmy N - Palm Springs, California

M's 3" AFO Split Short

The O.B.
The best shorts ever !!

I love these shorts and I wear them during my race, long runs and speed sessions. I own 4 pairs in black. My running friends love these shorts.
They are light weight, have a back pocket that holds my apartment key card or 4 running gels. They do a good job in trying to wick away the sweat while making me look fast and cool. I have had no chaffing issues.
