Sea To Summit Reactor Fleece Mummy + Drawcord Sleeping Bag Liner

From Backcountry

What Our Gearhead® Experts Are Saying:"I brought the Reactor Fleece Mummy + Drawcord Sleeping Bag Liner on a late October trip where temps dipped further than expected, and it genuinely saved me from a miserable night. The shoulder zippers made it easy to vent when I overheated on the climb in, and the drawcord footbox locked in warmth the moment temps dropped after midnight."The forecast said low thirties, and your sleeping bag says it's rated to twenty, so on paper, you're fine. But anyone who has ever woken up stiff and shivering at two in the morning knows that paper and reality do not always agree.
