Quick Overview


Thermarest Altair 0F Sleeping Bag

New for 2013 Thermarest have brought out a range of innovative sleeping bags to match their sleeping mats. In basic terms they have put an attachment system on the back of the bag to connect to the mat and taken most of the insulation out of the rear of the bag too. This is because you have the mat there for insulation and it saves an awful lot of weight, plus because of the attachments you won't slide off the mat anymore!

The design of the bag is such that there is room for you to move your shoulders, elbows and hips and it tapers to the feet and head for greater thermal efficiency. The mat connection system (Synergy link) will accept any mat up to 63cm wide.

Made with Polish goose down to 750 fill power this is a highly compressible, lighweight sleeping bag for all year mountain use. The big brother to the Antares.
