EVOC Seat Pack Boa

The BOA Fit system uses a dial-tensioned cable mechanism that wraps securely around your seat post. It allows you to tighten the bag quickly without needing tools, providing a much tighter, more stable connection than traditional Velcro straps.

It is fully waterproof. The construction is designed to keep your gear dry even when riding through heavy rain or splashing through puddles, so you don't need to worry about packing extra dry bags inside.

The BOA system is specifically engineered to minimize movement. Because it cinches tightly to the seat post and rails, it stays much more stable than standard saddle bags, even when fully loaded on technical trails.

Yes, but you need to be careful. While it is compatible with many dropper posts, you should ensure you have enough clearance between your saddle and the tire when the post is fully compressed to prevent the bag from rubbing against the wheel.

12 liters is a generous size for a seat pack, typically enough to hold a lightweight sleeping system, a change of clothes, or essential tools and extra layers. It is best suited for minimalist bikepacking setups where you are balancing weight and volume.
