Big Sky Tank Bag

Big Capacity. Clean Mount. Adventure Ready.

When your ride calls for serious storage up front, the Big Sky steps up. It’s our largest tank bag, purpose-built for larger ADV and touring bikes — but it's also at home on Enduro and mid-size dual sports. Big enough for your layers, lunch, first aid kit, and that “emergency” Snickers… or two.

Quick & Secure Setup

The modular base stays on your bike. Clip the bag on or off in seconds — no strap fumbles, no reset drama. Base mounting is rock-solid with three adjustable straps — two to the subframe, one around the steering neck. The bags built-in rear carry handle makes it even easier to grab and go.

Field Tip from the Trail

If you’ve ever tried to rethread a tank bag strap in a rainstorm with cold fingers, you know why we made this clip-in system. (We care about your sanity… and your vocabulary.)

Organized for Action

Inside, you’ll find a roomy, padded compartment with an adjustable divider — perfect for gear that should survive a tip-over. Two lid pockets, including one with a clear top, give fast access to small gear, maps, or your phone.

Adventure-Ready Design

Constructed from weatherproof ballistic nylon, featuring a storm-flapped main zipper and an included full rain cover — because “adventure” often means “rained on somewhere remote”. Outside, MOLLE loops, reflective webbing for visibility, and a top shock cord for stashing gloves or small gear during ride breaks.

Pro Tip

MOLLE isn’t just for tactical gear nerds. Strap on a tire pump or mount that mystery pouch you bought at a rally and still haven’t used.

Gear Interoperability

Uses the same strap mounting system as our Switchback and High Basin bags — switch sizes without rethreading straps.
