Reviewers were mixed on this base layer. While most people loved the heat it cranked out and found it very comfortable there were complaints that the heating zone on the back was a bit small. The fit may run a bit big but there is a very detailed sizing chart so be sure to measure yourself before ordering. It is also not as snug as you might expect for long underwear so consider ordering one size down if you want a tighter fit.

Venture Womens Heated Base

Venture Heat has been in the heated clothing business since 2003 when it was founded in Venice Beach, California. Their heated garments always get great reviews, and this base layer keeps that tradition going. This is available in a men’s and women’s version.

​​This heated long underwear is made from polyester and spandex which allows it to stretch to the perfect fit as well as provide plenty of flexibility when you are out on the slopes, sitting in a duck blind or hiking up a mountain. This is the latest version of Venture’s heated base layer which comes with 20 percent larger heating panels.

This base layer has three heat zones, one across the abdomen, a large one on the back and a third that runs across the shoulders. A 5.0V 5000 mAh battery cranks up the heat but it doesn’t last too long if you run it on high. You can get about 6 hours out of the battery on low but it drops down to 2 hours if you run it on high the whole time. This base layer is machine washable as long as it is in a laundry bag but should be air dried.

Reviewers raved about the heat but the battery life was a sticking point for many. Some claimed they only managed three to four hours on low and less than two hours on high. It is possible to purchase another battery to extend the heat which is probably a good idea if you plan on being out on cold for a long period of time.
