Two-way main zipper with rain flap — open from either side, covered against rain.
Dedicated 15.6" laptop compartment — plus a removable functional divider.
Three ways to carry — backpack, hand-carry, or slide onto a trolley handle.
Cross-bartack reinforcement — stress points stitched for durability.
Clean minimalist shell — PVC-coated, water-resistant, in four colours.
Sealock manufactures the Water-Resistant Business Laptop Backpack with Two-Way Zipper and Trolley Sleeve, model SL-E965, for commuters and travellers who want a clean, practical everyday pack. As a waterproof-bag factory, we build the body from PVC-coated fabric and cover the two-way main zipper with a rain flap, so this water-resistant backpack keeps rain and splash off a laptop and daily gear. Inside is a dedicated 15.6" laptop compartment and a removable functional divider; outside, a trolley sleeve lets it ride on a suitcase handle, and it also carries as a backpack or by hand. Cross-bartack stitching reinforces the stress points for years of daily use.
The main compartment runs a two-way zipper — two sliders so you can open from the left, the right, or meet them anywhere in the middle — and the zip sits under a covering rain flap that shields it from rain and splash. The PVC-coated shell sheds water, so the pack is rated IPX6 for wet-weather commuting: it handles heavy rain and spray rather than submersion. We confirm the seal on every unit with a heavy rain and water-jet test appropriate to that rating.
A dedicated padded compartment holds up to a 15.6" laptop against the back panel, and a removable functional divider lets you reconfigure the interior — split it for a laptop and tablet, or take the divider out for one big packing space. It is the flexibility that lets one bag work for a commute, an overnighter and a carry-on.
Padded, breathable shoulder straps and a top grab handle cover the everyday carries, and a trolley sleeve on the back slides over a suitcase handle so the pack rides on your roller through an airport instead of on your shoulders. Backpack, hand-carry or trolley — one bag for the door, the office and the gate.
A vertical zip pocket on the front gives quick access to a phone, keys, cards or a charger, kept separate from the main compartment. The clean front panel keeps the look minimal and professional.

Our OEM/ODM capability goes well beyond colour and logo changes: bring a sketch, a sample or a target spec — capacity, fabric, laptop size, interior layout, trolley and charging options — and our China base develops it from the ground up into a finished original product. Ground-up development needs longer lead time than a stock-colour change, so share your launch date and we will schedule sampling.
