If your adventures involve canyoning, rivers or persistently wet climates where your gear may be exposed to more moisture than the condensation inside your tent, a synthetic filled sleeping bag is a smart choice. The Sea to Summit Voyager Vy4 is filled with hollow fibre material that will trap warm air and keep you warm in any cold and wet (some would say miserable) environment!

Two layers of Thermolite® insulation is sewn into the bag in an offset shingle baffle construction that eliminates any cold spots where fill gets compressed along the stitching. On the outside, a 30D nylon shell features a DWR coating that minimises moisture ingress, and the bag is lined with a polyester that is both soft and warm to touch.

Decked out with all the features you expect in a technical outdoor bag including neck baffle, 3D hoot, draft tubes and side and foot zippers, the Voyager Vy4 has an efficient mummy design with a roomy foot box, it’s affordably priced and is the sort of bag that will keep you sleeping soundly on any cold and wet adventure.
