Waterproof Blanket

Available at select Costco locations in the USA

MSRP $69.99

Cold and blustery days are no match for the ALPTREK Waterproof Blanket. A waterproof and windproof outer layer keeps the elements out, and a plush sherpa fleece lining traps heat and provides a cozy experience. This blanket is perfect for any outdoor event and its larger size allows for sharing too! The waterproof outer layer also makes this blanket a great choice for picnics, since it will keep water from seeping through to the comfortable sherpa lining.
