NOW EVEN BETTER – We listened to your feedback and improved the fit, added softer lining material and upgraded the synthetic insulation.

  • Designed with warmth, compressibility and low weight in mind
  • Ideal for backpacking, camping and boat camping
  • With advanced PrimaLoft Synergy insulation
This lightweight and highly compressible synthetic mummy-style bag is perfect for backpacking or canoe camping. The insulation has been updated to the advanced PrimaLoft Synergy, a continuous filament synthetic insulation that’s warmer, softer and has more loft. It doesn’t absorb moisture when conditions are damp and still keeps you warm if it gets wet – it’s also more breathable than most insulations. Shingle construction layers the insulation within the bag, trapping pockets of warm air, eliminating cold spots and preserving loft. The fit is now more roomy and comfortable, giving you more space to stretch out. A new hood design provides more warmth, allows better range of motion and features improved adjustability. Both exterior and interior shells of the bag are constructed of a new ripstop nylon that has a soft, silky feel. Water-repellent treatment on outer shell resists moisture. Heavy-duty stuff sack and extra-large storage sack included. Imported. Front-load machine wash; air dry or use commercial machine.
