Why Add a Sleeping Bag Liner for Warmth
A sleeping bag liner adds an extra layer of insulation inside your bag, trapping body heat and boosting warmth without adding much weight or bulk. The Breeze Sleeping Bag Liner (Like New) from Second Summit is a lightweight option that also wicks moisture and feels soft against the skin, making it a practical choice for extending the comfort range of your current bag.
Because it is pre-owned but inspected to Like New condition, this liner offers the same performance as a new one at a lower price. The stretch-knit fabric moves with you, so it doesn’t restrict your sleeping position, and the moisture-wicking fibers help keep you dry on humid nights.
What the Breeze Liner Delivers for Warmth and Comfort
-
Breeze Sleeping Bag Liner (Like New): The blend of 70% Coolmax Ecomade and 30% biobased Tencel Lyocell fibres wicks moisture effectively to prevent you feeling clammy. Dry skin retains heat better than damp skin, so this liner helps maintain warmth even when you perspire.
Breeze Sleeping Bag Liner (Like New)
-
Breeze Sleeping Bag Liner (Like New): Available in both a Mummy version with a drawcord base, and a Rectangular model with a pillow sleeve. The Mummy shape fits snugly inside any sleeping bag for maximum heat retention, while the Rectangular version suits hostel or travel use where a pillow sleeve adds convenience.
-
Breeze Sleeping Bag Liner (Like New): HeiQ Fresh odour control technology helps keep the liner fresh even after extended use. Less odor means you can use the liner multiple nights between washes, which is handy on longer trips.
How to Layer the Liner for Extra Warmth
- Choose the right shape for your bag: If you use a mummy-shaped sleeping bag, select the Mummy version of the Breeze Liner. It stretches to fit any sleeping bag shape, and the drawcord footbox lets you seal in warmth. For rectangular bags or hostel sheets, the Rectangular model with a pillow sleeve works well.
- Insert the liner into your sleeping bag: Open your sleeping bag fully, then slide the liner inside. For the Mummy version, align the footbox with the bag's foot area. If your bag has a Free-Flow Zip system, the drawcord and shoulder openings are designed to integrate with it, so you can move without the liner bunching.
- Secure the liner for maximum heat retention: Pull the drawcord at the base of the Mummy liner to close the footbox. This prevents warm air from escaping and cold drafts from entering. For the Rectangular version, tuck the pillow into the sleeve to keep the liner in place.
- Use the liner alone on warmer nights: On mild evenings, you can sleep directly in the liner without a bag. The stretch-knit fabric provides comfort and moisture management, and the drawcord base can be opened so you can walk to the bathroom without fully exiting the liner.
Caring for Your Like New Liner
The Breeze Liner is made from a blend of Coolmax Ecomade and Tencel Lyocell, which are durable and easy to maintain. Wash it in cold water on a gentle cycle and hang to dry. Avoid fabric softeners, as they can reduce moisture-wicking performance. The HeiQ Fresh treatment helps control odor, so you can extend the time between washes.
Store the liner loosely in a dry place, not compressed in a stuff sack for long periods, to preserve the elastic fibers. With proper care, this Like New liner will continue to add warmth and comfort for many seasons.
