The Sleeper Expedition is Snugpak's most extreme temperature sleeping bag in the Sleeper Series range, taking good care of you in conditions right down to -17°C. Snugpak's design team have created a reliable, comfortable bag using soft-touch, siliconised fibres that form an insulated shell around you, and will see you happily through all four seasons.
The Sleeper Expedition is an incredibly warm, reasonably priced addition to the Sleeper range. Your only challenge will be parting with it in the mornings!
