The Robens Glacier I Sleeping Bag boasts a classic mummy style and features AirThermo insulation, a specialised synthetic fill that traps an insulating layer of warm air within its hollow fibres for premium heat retention, especially when damp. Plus, it provides a good lofting without being absorbent. YKK zippers are also used throughout for their renowned reliability, while a lightweight Ripstop outer fabric offers protection from both water and wind. Additionally, its unique profile lets the foot comfortably rest in a natural unrestricted position, and a handy internal pocket lets you keep valuables close at hand. More info
