Sea to Summit Spark -1C Long sacco a pelo in piuma

The Sea to Summit Spark -1C Long is a featherlight down sleeping bag that packs into a 4.3-litre compression sack while keeping you comfortable near freezing point. It is the go-to choice for backpackers, hut-to-hut trekkers, and climbers who measure every gram.

Advantages

Weighing very little and compressing to the size of a large grapefruit, this long-cut sleeping bag is a master of minimisation. The RDS-certified 850+ loft ULTRA-DRY Down™ provides outstanding warmth-to-weight performance, while the ultra-fine 10D nylon shell and liner feel silky and are surprisingly durable. A half-length left-hand zipper saves weight and makes nighttime access easy, and the tapered mummy shape reduces excess volume so your body heat is retained efficiently.
