The Thule Roundtrip 45L Boot Backpack is an efficient way to store all your winter accessories. This rear loading bag has a back panel door that doubles as a changing mat. The boot pocket even expels post ride stinky water with built in grommets. Gloves, handwarmers, and gaiters fit nicely in a side pocket, and for the Go-Pro you've almost lost 5 times this season or the goggles you've scratched, there's a padded top compartment to keep your valuables safer when you're not on the hill.
