SEA TO SUMMIT PREMIUM EXPANDER LINER

Why struggle with washing your entire sleeping bag when you could be out exploring? The Sea to Summit Expander Traveller Liner offers an easy-to-clean, budget-friendly solution to keep your sleeping bag fresh.  

Made from soft, super-stretchy poly-cotton, this liner moves with you as you sleep and provides extra warmth compared to standard cotton liners. Designed with a built-in pillow sleeve and fold-down top, it’s perfect for hostel stays and campsite comfort.  

An anti-microbial treatment keeps it hygienic and odor-free—without washing out—making this liner the most convenient and comfortable way to enhance your sleep while traveling.
