Thermozip James Baroud Sleeping System — Thermal Cocoon

James Baroud Thermozip Sleeping System: zipped thermal comfort for Rooftop Tent

THE Thermozip James Baroud is an insulating sleeping system that zips directly onto your tent mattress. It transforms your sleeping space into a thermal cocoon: extra insulation in winter, anti-condensation in all seasons, and easy storage (the bedding remains attached to the mattress — no need to store sleeping bags separately).

Designed to work seamlessly with James Baroud sleeping mats, the Thermozip comes with pre-positioned YKK zippers. You install it once, then simply open and close your sleeping bag like a giant down sleeping bag at each campsite. A real time-saver, especially on cold mornings when getting out of your sleeping bag at 3°C is far from ideal.

Why a Thermozip system?

The disadvantage of traditional duvets in a Rooftop Tent You slip during the night, your sleeping bag gets tangled up, and you're cold in the morning when you get out. The Thermozip solves these problems: it stays securely attached to the mattress, never slips, and allows for a smooth transition between the open position (lying flat on the mattress) and the closed position (like a cocoon). It's the natural evolution of sleeping for those who spend 50+ nights a year bivouacking on a rooftop.

Installation and maintenance

Installation is a one-time process: unpack the Thermozip, open it over the mattress, and zip the three YKK zippers along the mattress. That's it—you won't need to remove it again until your seasonal wash. For washing: machine wash at 30°C on a delicate cycle, dry flat or stretched (do not tumble dry). Washable 2-3 times per season without damage.
