Sea To Summit Spark SpII Sleeping Bag

Feel the lightness of true freedom as the backcountry cools, and trust the Sea To Summit Spark SpII to cradle you through the night. This isn't just an ultralight shell; it's a meticulously crafted sleep system for those who embrace fast-and-light principles, whether pushing for a dawn ascent or covering serious mileage across varied terrain. Its core, a phenomenal 850+ Loft ULTRA-DRY Down encased in a whisper-thin 10D nylon shell, delivers surprising warmth, comfortably rated to 36°F (and capable down to 27°F) despite weighing a mere 15.2 ounces. Thoughtful design elements, like the anatomical mummy shape and vertical chest baffles, prevent down migration and eliminate cold spots, ensuring consistent insulation. When compressed to an astonishing 1.3 liters, it virtually vanishes into your pack, leaving more space for adventure essentials. For shoulder season trips or any mission where every gram makes a difference, this Sea To Summit bag provides restorative comfort without ever slowing your pace.
