Add almost nothing to carry.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eA water-resistant backpack outer and a rain cover will take you a long way. But in prolonged rain, stream crossings or seriously wet conditions, water finds its way in through seams and zippers regardless. A backpack liner solves that from the inside — place it inside your pack before you load up and your sleeping bag, clothing, down jacket and electronics are protected by a fully waterproof barrier even if the outside of your pack gets completely saturated. Polycro film is extremely thin and lightweight, folding almost flat when not in use, so it adds virtually nothing to your base weight — the whole point for ultralight backpackers and thru-hikers who are already counting every gram. Each pack includes two liners so you always have a spare or can protect gear across two packs on the same trip. Choose Small for packs up to 30L or Large for packs up to 55L — both liners in the pack are the same selected size. As a bonus the polycro barrier also helps contain odours from food and clothing inside your pack, though it is not a bear-proof food storage solution.\u003c\/p\u003e","brand":"Next Horizon gear","offers":[{"title":"Large","offer_id":51624342782230,"sku":null,"price":19.95,"currency_code":"GBP","in_stock":true},{"title":"Small","offer_id":51624342814998,"sku":null,"price":14.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/3563\/4198\/files\/hikingpackliner.png?v=1785407157","url":"https:\/\/nexthorizongear.com\/products\/ultralight-waterproof-backpack-liner","provider":"Next Horizon gear","version":"1.0","type":"link"}
