Built for campers who want more space and less hassle, the OPUS® Deben 400 Smart Air Tent transforms camping into a truly relaxed experience. Packed with clever technology and smart design touches, it goes up in minutes and feels like home in moments—leaving you free to unwind, stretch out, and enjoy laid-back evenings under cover with total comfort and confidence.
At the heart of the Deben 400 is its brilliant smart power system, turning setup into a simple press of a button. Two detachable OPUS® Blow Bank batteries power the built-in self-inflation pumps, taking all the effort out of pitching and getting you camp-ready in minutes. And once the tent is standing proud, those batteries keep on giving—charging phones and tablets via USB-C and powering compatible lighting to create the perfect evening atmosphere. It’s camping made smarter, keeping you comfortable, connected, and confidently off-grid.
The Deben 400’s dual-pump self-inflating air frame transforms setup into a quick, fuss-free process, with the tent standing strong in minutes. Pre-angled air tubes create more upright walls than a traditional tunnel design, maximising usable space and headroom. Integrated roof bracer tubes add rigidity, improving stability in windy conditions and delivering reassuring strength throughout the structure.
The flysheet is made using OPUS® FSG150 fabric. The tough yet lightweight 150D material boasts a 5,000mm hydrostatic head and fully taped seams, delivering reliable protection when the weather turns. While the refined finish gives the tent a premium look that performs just as impressively as it appears.
Evenings inside the Deben 400 are transformed with OPUS® LED lighting compatibility. Zipped lighting holders are positioned throughout the bedrooms, living area, and awning, allowing you to create a warm, ambient glow exactly where you need it. Powered by the Blow Bank batteries, lighting remains practical, subtle, and completely independent of mains hook-up.
Outside, the Deben 400 is designed to extend your living space and enhance comfort. The fully enclosed integrated front awning offers sheltered space for relaxing, storing gear, or escaping sudden showers. Storm straps, high-visibility guy lines, and the Easy Peg system provide security and confidence in changing weather, while OPUS® Air Windbreak compatibility adds privacy, protection, and versatility to your pitch.
Step inside and the Deben 400 feels calm, spacious, and carefully considered. OPUS® Sleep-easy blackout inner tents create dark, restful bedrooms at any time of day, while the flexible 50/50 divider allows you to tailor the layout to your needs. Mesh ventilation panels manage airflow, the fully sewn-in groundsheet keeps out draughts and insects, and the included carpet adds warmth and comfort underfoot. Practical touches like bedroom pockets, cable management, and double-layer windows complete the experience.
From smart power and effortless pitching to spacious living and refined comfort, the OPUS® Deben 400 Smart Air Tent is built to make camping simpler, calmer, and more enjoyable. It’s a modern tent for campers who want more time relaxing—and less time setting up.
