Description: Sea To Summit Spark SP I 46 Long Sleeping Bag

Using the warmth of 850+ loft 90/10 Premium goose down, the amazing moisture protection of ULTRA-DRY Down, and a micro-weight 10D Nylon Shell and 15D Lining, we have created one of the best warmth for weight minimalist sleeping bags available.

The Spart is an ultra light big with many possible uses. Its balance of size, weight and warmth make it an excellent summer sleeping bag, especially for weight and space conscious cycle tourers and ultra light walkers. It also works well as a liner bag, slipping inside another sleeping bag t add one or two season to its rating.

The Spark compresses so small, we had to re-engineered our compression-sacks to make that reduced sufficiently. The ULTRA-DRY Down protection makes the Spark an impressive hard-alpine or adventure racing sleeping bag, where down has never before been a viable option, and weight is simply not tolerated.

Spark 1 features a contoured mummy shape with sewn through baffles for optimal weight/bulk/warmth ratio.
Spark 2 features a contoured mummy shape with sewn through baffles over legs, box wall baffles over torso.
Spark 3 featurte a contoured mummy with box wall baffle construction throughout and zip draft tube for optimal warmth.
