Sea To Summit Comfort Blend Rectangular Sleeping Bag Liner

The Softest Night in the Field – Sea to Summit Comfort Blend Rectangular Sleeping Bag Liner in Blue

Made from Sea to Summit's Comfort Blend fabric — a soft, skin-friendly material that feels genuinely pleasant to sleep in — this liner adds a cozy, clean layer between you and your sleeping bag without the technical complexity of the warmth-boosting Reactor liners. The rectangular shape gives you the freedom to move and sleep in any position, and the blue colorway is clean and easy to spot in your kit. If you want a liner that simply feels good to sleep in, this is it.
