Merino Heated Baselayer Shirt Men's - Black

[This review was collected as part of a promotion.] So far so good. Have ordered a few things for family as well. Sizes definitely are more fitted, be careful with that

The best heated base layer out there. Last plenty long enough. Used a handful of times so far, seems to be holding up well.

Great shirt, great product. The sizes run on the small side. Just order a size bigger and you'll be good to go

Great base layer shirt. Comfy. Always keep warm no matter how cold.

Perfect base layer and fits right. I'm a big guy with a belly and it fits decent.

I hunt in Alabama, where cold isn't extreme but conditions are tricky — cool mornings, rising temps, humidity, and long periods of sitting still. This base layer fits that environment perfectly. Fit & Comfort The merino base layer fits true to size and feels great directly on skin. The longer cut is intentional and smart — it stays tucked when climbing, sitting, and moving without bunching. Thumb holes are well-designed (not tight or awkward), even though I personally don't use them while hunting because I prefer bare hands on the rifle. Heat Performance (Real-World Alabama Use) The heat output is honestly stronger than I expected. Green (low): More than enough for cool Alabama mornings Blue: Ideal for staying comfortable during long sits Orange/Red: Very hot — honestly too much unless temps drop significantly That tells me the heating system isn't gimmicky — it actually delivers real warmth when needed. Most of the time, I run low or medium, and that's plenty. I don't want to feel “toasty,” just not shivering — and this nails that balance. Layering & Design This base layer works extremely well under a fleece and shell. The control placement at the bottom is perfect — I can adjust heat without removing layers. Once layered, I don't notice the controls at all. For Alabama hunting, where you often walk in warm and sit cool, this setup lets me: Walk in without sweating Sit without getting chilled Avoid bulky outer layers entirely Battery Life Battery life has been excellent so far, especially running lower settings, which is all I need in this climate. Why This Works So Well for Alabama Traditional “bulk up and layer” systems don't work great here — you overheat walking in, then freeze sitting. This base layer lets me stay lighter, quieter, and more flexible, while still controlling warmth precisely. Final Thoughts This is my first Fieldsheer product, and it absolutely earned my trust. The performance feels engineered, not marketed. If this is considered “mid-tier,” it's already more than enough for serious Alabama whitetail hunting. Highly recommended for hunters who deal with temperature swings, humidity, and long sits. Note: This review was written with the help of AI to organize my thoughts, but it's based entirely on my own real-world field use and prolonged discussion around performance, layering, and heat management while hunting in Alabama conditions.

I bought this shirt for my boyfriend. He works in cold temperatures and drinks a lot of hot coffee to keep him warm. He tells that this heated shirt is just the right thing he needs! When he is cold he switches the battery on and it keeps him warm, but if the weather is good he just wear it as a regular shirt. It looks so nice! I am thinking about buying one for me too!

I work in the cold storage facility and I do need a warm, REALLY warm shirt. This one was my first heated shirt and I love it. I love the fabric, its soft and nice. The battery lasts long and charges pretty fast. Heating elements are great. No issues so far. I would definitely recommend it!

I've never heard about heated shirt before! I got it as a gift 3 weeks ago and I am so pleased! It's the best gift I ever got! This heated baselayer is awesome! Well, I use it as a regular shirt now, since it looks so nice, but it will do the real job later winter time! I switch it on a low level if I need a quick warm and it lasts hours! The app is easy to use. Believe me, this one is the best gift ever!

Really comfortable I enjoy Wearing it the only issue is you must have battery with dc plug
