Available in both a Mummy version with a drawcord base, and a Rectangular model with a pillow sleeve, the stretch-knit fabric offers incredible freedom of movement. In humid conditions, the blend of 70% Coolmax Ecomade and 30% biobased Tencel Lyocell fibres wick moisture effectively to prevent you feeling clammy. Outdoor users will usually opt for the Mummy version - in especially buggy environments the Insect Shield® treatment repels certain bugs to provide greater confidence. And for those travelling, the Rectangular model has a built-in pillow sleeve that fits an Aeros Pillow perfectly. Rest assured you will have a hygienic sleep environment wherever you rest your head.
