Product Introduction

Sealock manufactures the 25L Waterproof Commuter Backpack with Front Waterproof Pocket, model SL-E1145, for riders and commuters who need a tough waterproof pack with fast zip access and room to expand outside. As a welded dry-bag factory, we build the body from premium 600D TPU laminated fabric with high-frequency welded seams, and open the main compartment on a waterproof zipper — so this waterproof commuter backpack keeps rain, splash and dust off a laptop and daily gear, with IPX6 protection for the wet commute. A front waterproof pocket, a 15.6" laptop-compatible interior and a MOLLE-compatible front panel round it out at just over a kilo.

Waterproof Zipper on a Welded Body

The main compartment opens on a waterproof zipper, and every seam of the 600D TPU shell is high-frequency welded with no needle holes — so water has no path in through the fabric. Rated IPX6, it keeps rain, splash and dust off your valuables for daily commuting and outdoor riding, and wipes clean in seconds. It is built for wet weather rather than full submersion; long-term immersion is not recommended at this rating. We confirm the seal on every bag with a heavy rain and water-jet test appropriate to IPX6.

25L Interior, 15.6" Laptop-Compatible

A spacious 25L main compartment organizes a laptop, documents, clothing, a lunch box, a camera and daily essentials, with an internal sleeve estimated to hold a laptop up to 15.6" against the back panel. An internal organizer pocket sorts the small stuff, so the pack works as well for the office as for the ride.

Front Waterproof Pocket and MOLLE Panel

A waterproof front zip pocket gives quick access to the things you reach for constantly — wallet, phone, passport, keys or earphones — kept separate and dry from the main compartment. Above and around it, a MOLLE-compatible front panel with reinforced attachment webbing lets you clip on carabiners, a bike light, outdoor tools, a water bottle or a small pouch, and an integrated D-ring adds a point for a keychain or accessory. It is the detail that lets the pack grow with the trip instead of forcing everything inside.

Ergonomic Carrying System

Padded, adjustable shoulder straps and a breathable mesh back panel spread the load and cut back sweat on the ride, and a reinforced grab handle makes the pack easy to lift off a rack. The abrasion-resistant TPU shell holds up to cycling, commuting, travel and outdoor use.
