Its primary role is hygienic: it protects the sleeping bag's filling from perspiration and direct soiling, which limits the frequency of washing and preserves its insulating properties over time.\u003c\/p\u003e\n\n\u003ch2\u003eDifferent materials and their uses\u003c\/h2\u003e\n\n\u003cp\u003eThe choice of material depends on the intended use and the season:\u003c\/p\u003e\n\n\u003cul\u003e\n\n  \u003cli\u003e\n\n\u003cb\u003eSilk\u003c\/b\u003e: the lightest and most compact of the three options, it slides easily inside a sleeping bag and provides a slight thermal gain.

Spacing out full washes of the sleeping bag thus preserves its thermal performance from one season to the next.\u003c\/p\u003e\n\n\u003cp\u003eIn mountain huts, some establishments require the use of a sleeping bag liner for collective hygiene reasons, regardless of whether you have your own sleeping bag. A lightweight, machine-washable model is recommended in these cases.\u003c\/p\u003e\n\n\u003ch2\u003eThermal gain: what you need to know\u003c\/h2\u003e\n\n\u003cp\u003eA sleeping bag liner can provide an additional thermal gain, generally estimated between 2°C and 5°C depending on the material and thickness. This value is indicative and varies significantly depending on usage conditions; it should not be considered certified data equivalent to a comfort temperature measured according to the EN 13537 standard. The liner remains a supplementary item, not a substitute for a sleeping bag suited to the actual temperature of the trip.\u003c\/p\u003e","products":[{"product_id":"sac-a-viande-5-c-aegismax","title":"Sleeping bag liner +5°C | Aegismax","description":"\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eFabric weight:\u003c\/b\u003e 100 g\/m²\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eShapes:\u003c\/b\u003e mummy (MMT5, MLT5) or envelope (EMT5, ELT5)\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eEstimated warmth boost:\u003c\/b\u003e +5°C\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eFabric:\u003c\/b\u003e breathable thermolite microfiber\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eSizes:\u003c\/b\u003e mummy M 182 cm \/ L 205 cm; envelope M 180 x 146 cm \/ L 196 x 148 cm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cb\u003eUsage:\u003c\/b\u003e inner liner for down sleeping bags\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch2\u003e+5°C sleeping liner for hiking and travel\u003c\/h2\u003e\n\u003cp\u003eThe +5°C \u003cstrong\u003esleeping bag liner\u003c\/strong\u003e slides inside a down sleeping bag to increase thermal comfort while \u003cb\u003ebivouacking\u003c\/b\u003e, in a mountain hut, or at a hostel.
