Our generously sized Basecamp sleeping bag range is also available in a non-down option. Two THERMOLITE® models may be the best choice when affordability is a primary concern, and when easy care is an issue (for instance when camping in desert or sandy riverbank environments). The same spacious, flexible design as the down Bc-versions are insulated with high-quality THERMOLITE® fiber, built into the bags using a unique WAVE LOFT™ construction. The inner fabric is an artificial silk made of polyester and has to be experienced to be believed. The Bt 4 has an EN rating of 5F / -15C (lower limit)
The Basecamp models have been designed to work with our sleeping mats and Aeros pillows to create a truly comprehensive sleep system. Slide your mat into the small pocket at the foot of the bag and then use the strap and loop set-up to secure the upper section. Then inflate your Aeros Pillow to the perfect pressure before securing it into place with the elastic strap.
