Small Sleeping Chamber is for replacement only, as the Kamaboko Tent (S) only allows for one sleeping chamber, already included with tent purchase.
Sleeping Chamber has two entries with zip-open solid doors and zip-open mesh doors, two windows with zip-open solid covers and permanent mesh covers, and a zippered e-port to pass wiring or external heater ducting into the tent.
The sleeping chamber floor is made from sturdy 210D woven polyester. The polyurethane coating makes it waterproof to 5000mm so you can be confident that you’ll stay dry in the most adverse conditions.
