Newly developed Alpine Fit combines ground level seams and re-profiled down distribution to optimise thermal efficiency and minimise weight and bulk. The highest quality goose down is brought together with our lightest fabrics and EXL ® technology for uncompromising performance and the highest possible warmth-to-weight ratio. Already amongst the lightest bags of their type in the world, the reworked Xero range remains the perfect choice for anyone who travels light and fast in difficult or remote environments.
