Perfect for damp conditions and when durability is needed.  


Created for rough and tough conditions, the Prism sleeping bag was conceived for expeditions where high levels of moisture are expected, durability is needed and consistency of function is a pre-requisite, regardless of the sleeping conditions, or what the sleeping bag has been through.

PRIMALOFT® is highly resistant to moisture and will maintain much of its insulation even when wet, whilst the PERTEX® Microlight outer shell is windproof, fast drying and highly breathable. One of the most technical synthetic sleeping bags on the market, the Prism has a tailored anatomical form and top stitch panelling across the body to prevent PRIMALOFT® migration.
