Mountain EquipmentXenith I Long - Sleeping bag

Without a hood to lighten the backpack, the Xenith I sleeping bag from Mountain Equipment is the lightest in the range, featuring goose down with a fill power of 900+ cuin. This filling traps air to insulate while maintaining a low weight and reduced bulk.

The Plasma 10D fabric, lightweight and breathable, has a water-repellent treatment that causes water to bead on the surface, without making the bag waterproof. The stiffened Gemini™ draft tube minimizes heat loss along the zipper and reduces the risk of snagging. The anatomical foot box provides a space tailored to keep feet warm.

For fans of light trekking and summer hiking in autonomy, its hoodless design emphasizes simplicity. The brand claims a Good Night's Sleep temperature of 5 °C, its benchmark for a good night's sleep, to consider when planning your stages.
