COR Surf 25L Waterproof Dry Backpack with Laptop Sleeve

Best fit: kayak and paddleboard day trips, surf, fishing and beach gear, wet-weather commutes, and short 1–2 day trips when you want a compact roll-top dry backpack with a built-in laptop sleeve.

The COR Surf 25L Waterproof Dry Backpack pairs a 25-liter main compartment with sonic-welded seams, a roll-top closure, padded shoulder straps, and a chest buckle. Its smaller footprint makes it the more practical of COR Surf’s two dry-backpack sizes for everyday loads.

Use-case match

• Water activities: designed to keep the main compartment dry around splashes, rain, kayaks, paddleboards, boats, and beaches.
• Wet-weather commuting: reflective strip, chest buckle, laptop sleeve, and two bottle pockets support bike or walking commutes.
• Short trips: 25 L is useful when a 40 L pack would be unnecessarily bulky.

Measured specifications

Water-protection boundary

COR Surf states that the pack floats if dropped in water. Correctly seal the roll top and keep electronics inside the main compartment. TripSpec has not independently laboratory-tested its waterproofing.

Choose another option if

• You need the extra space and 32 oz bottle compatibility of the 40 L model.
• You want a clamshell travel organizer rather than a single roll-top compartment.
• You need guaranteed airline personal-item acceptance. Airline and fare rules vary, so compare 18 × 13 × 7 in with the carrier’s current limit.
