Sea to Summit Talus TSIII -9 to 17 °C [Size: Long]

Sold Out

The Talus series offers some of the best warmth to weight sleeping bags but incorporated into the classic relaxed mummy design are many innovative and comfort enhancing features.

The hood is designed to cocoon your head completely in a way that maximises the available loft without making it feel claustrophobic. There is an adjustable collar to help fine tune your temperature control and both its draw cord channel and that of the hood are buried deep within the down so there are no harsh edges to push into your neck or face. There’s a discreet zippered pocket for your MP3 player or valuables, and the main zipper has an anti snag system that really works!

The cut of the bag and baffles are engineered so that none of the down is restricted from reaching its maximum loft (and therefore insulation value) – a simple principle to state but a surprisingly complex one to render practical. It involves using differentially cut, 3-dimensional side-walls and curved baffles.
