25L Waterproof Dry Backpack

If it gets wet, your gear doesn't.

The COR Surf 25L Dry Bag Backpack is built for the days when conditions aren't cooperating — kayaking, bike commuting in the rain, hiking into weather, or any situation where a regular pack would leave your gear soaked. Sonic-welded seams and a roll-top closure create a fully waterproof seal, and if it goes overboard, it floats. That's not a feature most backpacks can claim.

Inside, a padded 11" × 14" laptop sleeve protects your computer or camera gear from drops and impact — not just water. Mesh side pockets handle water bottles up to 24 oz, a top compression strap lets you lash bulkier items to the outside, and a chest buckle keeps everything locked in place when you're moving hard. The reflective strip earns its place on early morning or late evening rides when visibility matters.

At 25 liters it carries a full day's worth of gear without going oversized, and at 2.2 lbs the pack itself isn't eating into your load capacity. Padded ergonomic shoulder straps make it comfortable whether you're on a bike or on a trail.

Available in Black, Green, Gray, Blue, and Camo.
