Keep your ThermApparel cooling vest looking and fitting its best, wash after wash.

This 100% polyester mesh laundry bag is designed specifically for the ThermApparel UnderCool 3 cooling vest garment, CoolSleeve, and the headband. The open mesh construction allows water to circulate freely through the bag during the wash cycle, so your garment gets a thorough clean while the bag itself prevents stretching, snagging, and distortion that can happen when delicate stretch fabrics tumble loose in the machine.

Key Features

  • 100% polyester mesh construction allows full water circulation for a thorough wash
  • Protects the 4-way stretch fabric from stretching, snagging, or losing its shape in the machine
  • Designed for ThermApparel cooling vests (UnderCool 3,  CoolSleeve, Headband)
  • Simple zip closure keeps your garment secure throughout the cycle
  • Machine wash cold — just zip, toss in, and wash as normal

Note: For cooling packs, do not machine wash. Clean with mild dish soap and water only.
