Snack Mushroom Frame Bag

The bag uses a flexible three-strap velcro mounting system, which makes it highly adjustable for most standard bicycle frame geometries. It is designed to sit snugly against the top tube, but we recommend checking that you have enough clearance between your frame and any existing water bottle cages.

It is designed as a compact storage solution for small essentials. You can comfortably fit items like a multi-tool, a spare tube, a set of keys, and a few energy bars, but it is not intended for bulky items like a full-sized pump or a heavy jacket.

The bag features a water-resistant polyester exterior and a waterproof zipper, which will keep your items dry during light rain or road spray. However, it is not fully submersible, so we advise using a small dry bag inside if you are carrying sensitive electronics during a heavy downpour.

When the three velcro straps are pulled tight, the bag remains very stable. Because of its compact size, it doesn't have enough mass to cause significant sway, even when you are standing up to pedal or navigating bumpy terrain.

Yes, the waterproof zipper is designed to be accessible. However, because waterproof zippers have a tighter seal to keep moisture out, they can offer slightly more resistance than a standard zipper, so it is always safer to open it while stopped.
