Sea To Summit Spark Spi

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 SpI 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 mummy shape, full hood and short zip conserve heat efficiently, and vertical chest baffles prevent migration when horizontal. Even better – it’s so thin it can be used as a liner or booster bag to add several degrees to your other bags. Talk about versatility. All this and it fits in the palm of your hand. Comes with compression sack and storage cell.
