A WEATHERPROOF, EXPANDABLE BIKE SEAT PACK WITH EASY HOOK AND LOOP ATTACHMENT.

A weatherproof seat pack that gives you room to grow, the roll-top Tail Light expands when you need it and compresses when you don't. Its slick poly fabric enhances the weather proofing of its roll-top closure, and a large vista loop offers a sturdy and reflective place to attach a tail light for being seen in the saddle. A simple, secure hook and loop attachment system keeps the pack in place, making this intelligent seat pack easy to figure out.
