Product Description
Sealock Waterproof Technology
Lightweight Airtight Waterproof Backpack · 15L
An ultra-lightweight, 400g technical gear pack engineered with fully airtight zippers and a thermal-welded TPU lining. Delivering IPX6 heavy-wave defense, it securely safeguards your 15" workstation in extreme marine and watersport environments.
IPX6 WATERPROOF
100% AIRTIGHT ZIPPER
ULTRA-LIGHT 400G
Core Waterproof Engineering
Sealock Airtight Zipper
Proprietary hermetic zipper mechanism that forms a completely sealed internal chamber. Maintains internal pressure and blocks absolute moisture intrusion.
420D Ripstop Shell
High-density mini-grid weave treated with an advanced DWR (Durable Water Repellent) coating. Hydrophobic tech ensures water beads up and rolls off instantly.
TPU Welded Chamber
The interior compartment features 100% RF-welded TPU lining with zero needle holes. Ensures bulletproof protection during heavy-spray environments.
3D Honeycomb Panel
An integrated molded mesh suspension layout that maintains a continuous air-channel across your back, avoiding heat and sweat build-up.
15" Laptop Vault
An independent internal compartment lined with scratch-resistant premium soft fleece, keeping your laptop perfectly dry and isolated.
Systematic Partition
Features an airtight main chamber, 1 secure zippered inner pocket, and 4 specialized card slots to organize essentials in moisture-heavy environments.
Technical Features Break Down
- IPX6 Rated Hermetic Chamber: Driven by the Sealock patented airtight zipper, the entire pack seals tightly to withstand high-pressure water jets and continuous severe ocean sprays.
- Dual Layer Defense: The 420D Ripstop shell works in perfect synergy with the internal hot-press TPU lining, establishing an uncompromising double-barrier against moisture.
- Airtight Front Access: The frontal arc pocket utilizes a dedicated water-tight zipper, providing zero-compromise sealing and rapid access for essential electronics, wallets, or passports.
- Fleece-Lined Workstation Pocket: The dedicated 15-inch laptop vault shields your high-value digital devices from mechanical vibrations and sudden shocks.
- Structured S-Strap Suspension: Outfitted with 3D honeycomb mesh padding and an adjustable ergonomic chest buckle to distribute weight evenly and prevent side-sway during swift movements.
- PP Core Rigid Handle: The top grab handle integrates a structured internal PP skeleton wrapped in heavy-duty webbing, allowing easy rinsing and reliable overhead hoisting.
