## How Nova Adapt differs from other cooling comforters
Most cooling comforters use a breathable cotton shell to vent heat passively.
Nova Adapt is an active thermal loop: phase-change microfibers in the fill
itself absorb body heat when you run hot and release it back as you cool.
Combined with aerospace-grade graphene fiber that generates gentle warmth on
contact and a reflective layer that returns 98% of body heat, it is a closed-
loop regulation system rather than passive insulation.
