    Madison ★★★★★

    We fit two adults plus a dog in this thing and still had room to stretch out, and the cotton liner feels like a real bed sheet against your skin. The mummy-style hood cinched down tight enough that even my drafty shoulder gap stayed warm all night.

    Grace ★★★★★

    The draft tubes are a lifesaver—no cold air sneaking in when my partner rolls over at 2 a.m. We both fit comfortably without fighting for space, and the cotton liner feels way softer than the usual polyester.

    Sophia C. ★★★★★

    We took this out in 18°F weather and stayed toasty all night, the cotton liner is genuinely soft against the skin and the draft tubes kept every cold breeze from sneaking in. The mummy-style hood cinched up perfectly around both of us, so no more fighting over the blanket.
