Sea To Summit Spark Down sleeping bag -18C Beluga

Description

When the frost is biting outside and moisture is building up inside the tent, you want just one thing: warmth, peace of mind, and confidence. The Sea To Summit Spark Down sleeping bag -18C Beluga gives you reliable sleep, even high in the mountains.

Main benefits

A -18 °C limit temperature and mummy fit help keep warmth where your body truly needs it. The technical hood and anatomically shaped foot area reduce heat loss during the night.

Insulation made from 90/10 goose down with RDS certification and 850+ fill power delivers excellent warmth for minimal weight. The PFAS-free Ultra-Dry Down treatment resists moisture better and dries faster.

The inner 10D nylon is pleasantly breathable, so you’ll sleep better even after a demanding day. The outer 10D nylon with non-PFAS DWR reduces water absorption when it comes into contact with tent condensation.

The full-length YKK #5 side zip with a protective guard makes venting easier while preventing snagging. The sleeping bag can be zipped together with the Women's Spark model with a full-length zip.
