Product description

Mummy sleeping bag with a minimal pack size and excellent thermal performance

The Spark SpIII sleeping bag from Sea to Summit is not only ultralight weight and extremely packable but also incredibly warm. The design reflects the demand to defy the most diverse weather conditions with a sleeping bag that is as light as possible. The Spark 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. The nylon outer and lining, the baffle construction and the down fill deliver efficient insulation and the best possible warmth-to-weight ratio.

High-quality down fill and plenty of space

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 SpIII remains spacious and comfortable, even if you’re wearing an extra layer of clothing. The side 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, the Spark SpIII sleeping bag is a solid option for lightweight adventures in places where down has never really been a viable option before.

The advantages at a glance:

  • Mummy sleeping bag with a small pack size
  • High-quality down fill has a strong thermal performance
  • Plenty of space for clothes inside 
  • Comfortable entry and variable ventilation
