Temple Tape Skull Cap Beanies are created with 3 different purposes in mind. Our first goal we had when designing this product was, we wanted this Beanie to be light weight while still keeping your ears and Head warm. Our second goal we had is for this beanie to comfortably fit under any Hardhat, Helmet or Hat. The last goal we had when developing this beanie was we needed the material that we used to be Moisture wicking and sweat absorbent. After 2 years of research and development we finally came out with the perfect blend of material to achieve our vision. The outer layer of the hat provides the moisture wicking abilities. The inner Layer of the hat is lined with a super fine brushed fleece which provides the thermal retention. The sleek design allows for this beanie to be used under any type of hard hat, Helmet or Hat. The light weight material and Temp Dry Technology allows for this skull cap to be used all year around. Great as a Birthday, Christmas, or any holiday Gift.
