Women's Heated Baselayers

Why start with a heated base layer?

A heated base layer is the warm foundation the rest of your layers build on, worn right against your skin where heat does the most good. Slim and smooth, it disappears under whatever you wear on top. Browse the full heated base layers range to see the options.

How long does a women's heated base layer stay warm?

Our women's heated base layer stays warm up to 10 hours on low, and about 2 to 3 hours on high. Because it warms you at the source, you can leave it low most of the day. Keep a spare battery on hand for long days out. Cold shortens any battery, so keeping the pack in its pocket helps it last.

Can you wash a heated base layer?

Yes, our heated base layer is machine washable. Remove the battery, machine wash cold on a gentle cycle, and tumble dry on low, skipping bleach, ironing, and dry cleaning. Treated this way, the panels last for many seasons. Because it sits against your skin, wash it after a few wears to keep it fresh.

Do the men's base layers use the same heat system?

Yes, the men's heated base layers share the same panels, four settings, and battery in a men's cut, so a matched pair runs and charges the same. The 7.4-volt battery works in either one, so a single set of spares keeps you both powered.
