Cole Crosby's review
I used to suffer from bad chafe in races, especially in 200 milers. Since using Path Projects base liners, life has been a lot more enjoyable in my races. I love having a separate underwear underneath my shorts to prevent chafe and help insulate those "crown jewels"

Keeps the chafe to a minimum and still lets the bits breathe

Polartec fabric with stitchless seams. These have a wider waistband so the shorts stay in place and don't ride up. Zero chafing with this combo.

The Lynx PD liners are my go-to liners if I am wearing a two layer short system. They have just the right amount of compression to keep everything where it's supposed to be, without being uncomfortable. They are very comfortable and dry well too! I prefer a two layer short system for 100 milers, that way I can put shorts overtop of the liners, and when it gets cold I can easily change to some pants without having to get naked at an aid station

When you’re putting in serious miles, what’s under your shorts matters. The PATH Projects Lynx PD base liners are a favorite in my running gear, comfortable support that helps me focus on the miles ahead. I wear these under my shorts while training for Tunnel Hill, and they’ve earned their spot in my long-run lineup. If you’re building mileage, give these a look! I wear an XL.
