EVOC Seat Pack Boa

Yes, the Seat Pack Boa L is specifically designed to be compatible with dropper posts. Its mounting system and shape ensure it won't interfere with the post's travel or cause damage during operation.

The Boa Fit System uses a dial-tensioned cable to cinch the bag tightly against your seatpost. It provides a much more secure and stable fit than traditional Velcro straps, preventing the bag from swaying while you ride.

It is 100% waterproof. The construction and roll-top closure are designed to seal out rain, mud, and road spray, keeping your spare tubes, tools, and extra layers completely dry.

No, you don't need to worry. The bag features soft TPE (thermoplastic elastomer) protection at the contact point, which prevents scratching or abrasion on carbon or alloy seatposts.

The 3L capacity is ideal for essential ride gear. You can comfortably fit a multi-tool, a spare tube, a tire lever, a CO2 inflator, and a lightweight windbreaker or gilet.

The roll-top closure is designed for flexibility rather than quick-access speed. While it takes a moment longer to open than a zipper, it allows you to compress the bag to the exact size of your load, ensuring nothing rattles around inside.
