Outwell Constellation Lux

The Outwell Constellation Lux is an extra-warm, rectangular synthetic sleeping bag made for camping in chillier conditions. With a comfort rating down to around –2 °C, it’s designed to keep you cosy on cool nights while giving you the freedom to move or unfold it as a blanket.

Its secret lies in the Isofill premium insulation—1 550 g of 100% polyester fibres that trap heat efficiently and maintain loft even if damp. The hard-wearing nylon-polyester outer resists abrasion, while the soft lining feels gentle against your skin. At its generous size, it easily accommodates sleepers up to around two metres tall, so you won’t feel cramped.

Isofill is a synthetic fill made entirely from polyester, with fine fibres engineered to create air pockets that hold warmth. Unlike natural down, it continues to insulate when wet and dries more quickly, so you can count on consistent performance in variable weather. The blend of nylon and polyester fabrics also helps manage moisture and adds durability for years of use.
