Baseframe Pro SL Base Layer

Craniums get all the attention in the protection world, but with Fox's Baseframe Pro SL sleeveless protection vest you can put your core in the spotlight. This compact vest features armor on the hips, chest, and spine, elevating safety while you ride. It utilizes F3 impact foam that provides full coverage, without restrictive movement. On the back, large perforations and flex grooves contour and flex with you while you ride, so you can forget that you've got armor on at all, until you overcook a berm and wind up in the bushes. F3 body armor offers unique traits that harden on impact, and soften with body heat, allowing the foam to mold to your unique anatomy, while still giving you serious backup when you need it. Open stretch mesh makes up the body of the vest, allowing for serious ventilation and moisture wicking while you ride.

Nice pads

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

Really nice fit and comfortable to wear. It is a bit hot but not really much more hot than wearing a base layer. Wore it on a pedal fest and it didn't flop around at all.

Light and cool

I've put it through the wringer
Size Bought:
6' 1"

I really like the baseframe pro SL for enduro style riding. It breathes very well on the front and sides, has solid protection and doesn't get super stinky if you rinse it after use. Hip pads were a great inclusion. I wish the back protection was a bit lower profile as it does stick out a bit more than my other low profile armor and it doesn't breath as well as it could so you'll get a sweaty back. It's a minor gripe though as it's still pretty slim. I'm 6'1, 190lbs with a 45" measured chest so got the XL. Probably could have gone with the large.
