Bike Bros. Black is Faster - Bike Bros Jersey

These are a slim fit, but not skin-suit tight so work nicely for trail rides, gravel, road rides etc. Just not for a UCI time trial - too flappy for that. The fabric is surprisingly comfy and cool on the super hot days.

The full zip makes for on demand ventilation and you won't need to Mel Gibson your shoulder to peel off the thing after a hot, sweaty ride.

We designed these with a little more room at the arm holes so riders with huge guns (no starving roadies here) don't end up with numb arms and purple fingers... but not t-shirt floppy... just right.
