Keep your cargo slim and centered with Apidura's Full Frame Pack. The Polyan VX21 main body is lightweight, tear-resistant, and waterproof to handle whatever environment your next trip brings your way. Two water-resistant zippers open into a side-pocket and large main-compartment with removable divider, and there's also a hose-port for routing hydration bladders or headlight battery cables. Inside, the liner is bright yellow to help your gear standout in low light so you have no problem finding what you need at the bottom of the pack.

Note: While this pack is constructed using waterproof materials, moisture may enter the bag during sustained or heavy rain. The use of a dry bag is recommended when carrying products sensitive to moisture.

Great triangle bag for round town errands and bikepacking
by ChrisP

This is my fourth Apidura bag purchase - I'm impressed by the functionality and durability of their bags. I use it daily for errands (you can fit a bag and more of groceries if you don't mind cycling bow-legged) and have taken several bikepacking trips with it, where contained my tent, poles and air mattress. Recommended!

Was too big for a 55 bike

The bag itself is very nice, but like I said if you an average sized person on a MML bike, this thing will not fit. I returned in favor of the Blackburn medium frame bag
