These are awesome on those really cold days!
First, the customer service at Pnuma is top-notch. I needed the long-sleeve thermal within two days so I called customer service and they were awesome. Got directly connected to someone right away and they ensured I would get the thermal within 48 hours and even put a rush delivery on it. I went out muzzleloader hunting for mule deer in western Nebraska during the December cold snap of -40 to -60 below zero and the thermal worked great. I didn't even need to turn it on until I was done walking/cutting off the herd where the buck was, but once I did power it up, it was instant heat. It's very comfortable also and fits like a dri-fit compression shirt. I am 6'2" 205-210 with muscular build and the Large fits perfectly. I also used the Waypoint pant and matching jacket on the hunt and I'm impressed with their products thus far and will be using them for years to come. Thanks, Pnuma!
Best investment I've made for late season Wisconsin hunts and ice fishing.
Buy extra batteries! Only complaint is the battery life and position they sit on top of eachother which creates bulk thats uncomfortable while sitting, also the connection lenth and plug...the lenth should be longer and use a usb plug so you can use a charge pack positioned where you want and 20,000mah would last all day long. Other than that quality and heat are top notch
I like this very much I even had the best this is way more comfortable would recommend it to anybody
Tried this shirt during bow hunt a 8 degree day with normal base layer and jacket was comfortable for 3.5 hours. Material seems pretty outstanding and fit very well
