The RPET Cooling Towel opens to 31 1/4" x 12 1/16" and is lightweight. It’s made of 100% recycled PET, from recycled plastic water bottles. Use this at the gym, when running or working out as it is ultra-soft and super absorbent. It is great for hot and humid conditions. It can absorb your sweat and keep you cool and you can drench it in cold water, wring it and put it over your shoulders to keep you cool after a workout.
