The Salewa Cotton-Feel Silverized Sleeping Bag Liner is a 260 gram rectangular liner with an integrated pillowcase, treated with silver ions against odour. A liner does two jobs: it keeps the sleeping bag clean, and it means a hut blanket or a hostel bed becomes something you are willing to get into.

• Cotton feel without cotton: the fabric is listed as polyester and named for how it feels against the skin.
• Silverized treatment: silver ion finish to hold down odour over consecutive nights.
• Weight and packed size: 260 g, packing to 10 by 22 cm.
• Dimensions and shape: 225 cm long with an 80 cm shoulder and knee width, rectangular, not mummy shaped, so it does not fight a bag's cut.
• Integrated pillowcase: at the head end.
• Keeps the bag clean: far easier to wash a liner than a down bag, and washing a down bag shortens its life.
• Colourway: Offwhite.
