The Trekmates Cooling Crystal Scarf is lightweight, comfortable & keeps you cool in the heat for days due to polymer crystals that are stitched into the central section. Once submerged in water [for approx. 4 mins] the crystals will absorb & retain the water keeping the wearer cool for up to 3 days before they dry & slowly return to their original state, ready to be re-submerged. For extended cooling effect they can be refrigerated or placed in freezer. The Trekmates Cooling Crystal Scarf
- ideal for wearing around your head or neck when in hot climates.
