Zach Bitter Signature Series 5 Inch Racing Shorts

The best quality performance fabric I've worn hands down. Purpose will be my one stop shop for all things triathlon/ cycling performance wear.

Loving these shorts - comfortable, light-weight, and functional.
My only complaint is that they don't make me run like Zach Bitter - can you produce some of those?

Zach bitter signature series is a very comfy, light and stretchable shorts. Very useful for runners and i like it so much.

I own lots of running shorts from many brands and these are the best. They are great for hot weather because they are so short and light. They have a phone-sized pocket on the back, and a minamalist waistband - it's just elastic so it doesn't have extra cloth around it. The reflective features are great, too.

Good fit and light feel, able to run long with these shorts. Great price/quality

Definitely one of the most comfortable pair of running shorts that I have ever worn. Love the cutting, design, material and the large back pocket. If there is one comment that I would make, the back label could be made smaller, or with softer materials, or easier to be removed so that it does not cause any chafing during long runs. Keep up the good work in creating this running line!

The biggest challenge for Purpose is they set such high standards that we expect more and more!! The fit and design of the shorts is great and they feel really comfortable. I'm a very heavy sweater so within 30 minutes I'm soaked! if I had one suggestion it's to make the material lighter in particular for people like me who have a high sweat rate and looking to do longer runs...1 1/2 hours+

This is Purpose first running shorts and I would say its comparable to my favourite running shorts. Its comfortable, breathable and offers good hip range of motion. Plus point is the generous zip pocket on the back which will fit today's larger screen mobile phone or several running gels.

Was positively surprised to see that the Zach Bitter collection contains Purpose's first running shorts. Knowing Purpose good quality products I was very keen to test it. After getting quick help via Facebook messenger from Purpose to identify the right size for me, I ordered and received it within 24 hours!
The shorts are very comfortable, the material is light and what I especially appreciate is the generously sized back pocket. It allows to take along pretty much everything you wish for, like car key, phone, a zipper bag for your face mask, etc.. My first run in the shorts was a time trial, very intense and I was soaked in sweat. The shorts felt perfect throughout the session. The shorts were worth all the wait. Highly recommended
