Product description
The top model in the Spark series
Designed to withstand various weather conditions and be as lightweight as possible, all Spark sleeping bags are not only ultra-light and extremely packable but also incredibly warm. The Spark SpIV sleeping bag owes its incredible performance to the perfected design and premium materials. It’s filled with very high-quality 850+ Loft 90/10 goose down, which has been treated with ULTRA-DRY Down to fend off moisture coming from the inside and outside. In addition, the sleeping bag is equipped with the extra-light YKK #3 zip as well as a shell made of 10D nylon and a 7D lining. When combined with the contoured mummy shape, these materials deliver efficient insulation and boast one of the best warmth-to-weight ratios you can find.
Ultralight and optimally insulated
The vertical chest baffles contain a large amount of down and distribute it evenly across the upper portion of the bag to prevent cold spots. Thanks to its expedition size, the Spark SpIV remains spacious and comfortable, even if you’re wearing an extra layer of clothing. The full-length zip with two sliders makes for easy entry and gives you a variable ventilation option. The draught tube, hood and draught collar work together to provide optimum insulation. Thanks to its incredible design and excellent features, this sleeping bag is a solid option for lightweight adventures in places where down has never really been a viable option before.
