Description

<p>On winter tours and expeditions you have to carry a lot of equipment, but with the Spark SpIV sleeping bag from Sea to Summit you can save a lot of weight and volume. Although it stays under one kilo, it convinces with its strong performance at low sub-zero temperatures. In the revised version, it also offers extra comfort thanks to a modified cut. Equipped with the highest quality 850+ cuin Ultra-Dry Daune™ and particularly lightweight outer and inner fabrics, the Spark achieves an excellent warmth-to-weight ratio. The goose down is completely certified according to the Responsible Down Standard (RDS) and therefore comes from species-appropriate husbandry. Due to the waterproofing, it absorbs significantly less moisture, which means that it retains its excellent bulk strength even on long tours and in humid regions.</p><p>New to the Spark SpIV sleeping bag are the longitudinally positioned chambers on the front. Thanks to them, the down inside slips less, even if you move a lot at night. In addition, the cut has been adjusted to allow more space in the shoulder and hip area. Not only does this make the Spark more comfortable, it also offers the option of adding an extra layer of clothing or a liner. Nevertheless it keeps its minimal weight and its small pack size - perfect for tours where every gram counts.</p><p>The Spark SpIV can withstand even the toughest demands, but is aimed at minimalists who are also on the move in icy temperatures. Therefore it cannot be coupled, but has a continuous two-way zipper that allows ventilation.</p>
