You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.

The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!

I bought the base layer for my son who works at Disneyland in Anaheim Ca. and he loves it. Keeps hos 3X body warm when working nights. Great product

Just wearing the shirt and not on has been enough to keep me warm. The few times I have used the heat, I set it on lthe lowest setting and was plenty warm.

Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters

[ I am getting synthetic products out of my wardrobe and I have become addicted to Icebreaker long sleeve layering shirts. They are extremely comfortable, come in a variety of nice colors and weights, so are quickly replaced my synthetic top layers.

The Greek
[ This is one of two or three of the most amazing clothes I have. Technically it's a base layer but it's something I wear almost anywhere with the right pants and shoes. It's wool, but it's incredibly soft and comfortable. It works great as a base layer, but it's versatile.

I bought this for my teen to use as a base layer for skiing and sledding. It kept him dry and warm and fit him well.
