Its bow n Arrow season here in n.y. n couldn't wait n try my new skin-fit Base Layer . Loved it in the early morning 34 degrees that it kept me nice n warm. The only problem was that where the batteries slide into n pulg into they both popped out of their pockets probably climbing down the tree n lost "one"walking out n realized it back at the truck. Walked back to tree n sitting on the ground was my battery, so you should Velcro it like i did. Just a suggestion like u did with ur heated vest that i also wear. THANKS AGAIN FOR UR GREAT PRODUCT, BOB ROHRIG

So good I didn't even notice it

Compact size. Long lasting charge.
