When heat and lightness are your two priorities, the light and compact ultrasphere 4.5 -awarded inflatable mattress is the equipment you need. Its revolutionary conception includes two layers Tilt Thermo-reflective, which reduces the loss of heat by radiation, as well as offbeat air compartments which trap heat inside the mattress, allowing you to regain forces comfortably without bulky insulation. Associated with a soft and incredibly light fabric, the light construction of the mattress makes it the ideal companion for bicycle trips, itinerant hikes and mountain races of several days.

With a comfortable shape of tapered sarcophagus that eliminates unnecessary congestion, the thickness of the mattress provides good support so that you can rest and recharge your batteries for your next sports days. The discreet two -lane valve and the inflation bag simplify and accelerate the installation of the camp when the night is approaching.

With a set of repair included and an unequaled weight/heat ratio, the ultra -sphere 4.5 mattress is designed for dynamic adventures in hostile mountain conditions.

Compatible with all our sleeping bags, the 4.5 ultra -sphere mattress forms an ultralight sleeping system weighing less than 700 g when used with Our ultra 120 mythic modular bag.
