Sea To Summit has created the SPARK PRO -1C/30F LONG sleeping bag for those who want to hike or travel with lightweight gear without sacrificing comfort or safety. Highly compressible, it fits discreetly in your backpack, and its sarcophagus shape optimizes warmth close to your body.

The insulation is made from an excellent RDS treated Ultra Dry Down goose down, offering superior water resistance in very wet conditions and a comfort temperature limit of -1C. The 950+ loft is incredibly captivating, enveloping you in a cozy cocoon. You'll immediately feel warm and comfortable.

The fabric inside and out is made of ultra-light, waterproof and breathable 10D nylon, which also offers excellent protection against condensation. It features three zippered openings. The first is a full-length zipper with a double slider, while the second is a 1/4-size zipper that lets you adjust your comfort to your liking. Finally, a third ultra-light zipper allows you to open only the foot area.
