Description

ULTRA-DRY Down™ security and warmth in a tiny pack.

Utilising the warmth of 850+ space 90/10 goose down, the astonishing moisture protection of ULTRA-DRY Down™, and a micro-weight 10d Pertex® shell and 15d covering, has made one of the best warmth for weight moderate sleeping bags around.

The Spark is an ultra light sack with a few key components. The balance of it’s size, weight and warmth make it magnificent as a late spring sleeping bag, particularly for weight and space conscious cyclists and ultra light walkers. Its size and warmth rating works well as a liner sack, slipping inside an alternate sleeping bag to add 1 or 2 seasons to its rating.

The secret to the Spark’s warmth to weight is the premium quality down and superior micro-weight shell and liner fabrics, the 1/3 length light-gauge #3 YKK zip and the sewn-through transverse baffle design.

The Spark packs up so tiny, Sea to Summit had to re-work their packing sacks to make one that fit it’s small size!

The ULTRA-DRY Down™ security makes the Spark an excellent hard-alpine or expedition sleeping bag, where down has at no other time been a reasonable choice, and weight is basically not wanted.

1/3 Zip Mummy

The Spark is shaped as a closely fitting mummy pack. The full hood, foot box and short zip expand fit and warm while keeping weight and size to an absolute minimum.
