Sea To Summit Spark Spiv

Description

Updated for 2019, Sea to Summit’s Spark series of sleeping bags are designed to be the pinnacle of lightweight warmth for any conditions – an ultralight down bag for travellers, adventure racers and minimalists of all persuasions.

The Spark SpIV uses the highest possible quality of responsibly-sourced down, 850+ loft, Ultra-Dry water repellent European goose down, and an ultra-thin 10D nylon shell. It’s no slouch in the design department either: the contoured mummy shape, full hood and draft tubes (zip, neck & hood) conserve heat efficiently, and vertical chest baffles prevent migration when horizontal. At 880g this has to be the lightest -15°C bag in the world. All this and it fits in a 3.3 litre bag! Comes with compression sack and storage cell.
