Wish it had another heating element in the lower back. Fit is as expected.

I had my eye on this top for quite a while, and the sale made it too good to resist trying. This was the only brand I found that offered a Womens XS option, so I took a chance and placed an order. The top is pretty true to the measurements, but not as fitted as I was hoping...but is still cut close enough to work well as a base layer and be able to be layered appropriately. The heating elements are positioned effectively throughout the top and it does indeed warm you up fast! I work outside (barn/farm work) so the chill can set in fast depending on conditions and activity level. I turn it on high for 3 or 4 minutes, get the chill out, and turn it off; or if sitting still, I run it on low for 15-20min to warm my core, and that has been doing the trick. For reference, I am 5'2", barely 105#, and have a very petite but athletic build. I get cold very easily and overall do not handle cold well, hence the investment in some heated gear. The battery is compact enough but good size to do the job well. On me, the battery pack sits on my left front ribs, but has not caused an issue with mobility, layering or being uncomfortable.

Bought for my girlfriend, who works outside. It keeps her warm. I reccomend getting a 9300mah battery to go with it if you use it daily. One in the shirt and on the charger.

I bought this for a friend who is always cold. She said it was very warm and very comfortable. After her review, I am going to get one for me!

Though overall the shirt seemed to be of good quality, the wires inside that comprised the heating element were snagged into a big snarl, big enough to make a lump through the shirt and feel uncomfortable when worn, and I couldn't untangle them through the shirt. I also suspect the heated area was reduced compared to if they had lain flat like I suspect they're supposed to. The fit was off as well. I usually wear a XS-S in most base layers and prefer a slim but not skin-tight fit (for east of fitting underneath other clothes). I ordered a S. The fit was quite baggy, but the neck hole was snug enough that it was a bit of a struggle to get my head through it. I think my head is of average size - at least, I don't usually have trouble with the necks of my shirts. If I'd tried a smaller size to remedy the baggy fit I suspect I wouldn't have been able to get my head through. However, sleeve length was good (I have long arms) and shirt length was good too (no lower back flashing). Maybe I just got a dud with the tangled wires, but I would have sent it back due to the baggy fit anyway. Besides the messed-up wires, the neck, and the fit just not to my taste, it was a nice shirt.

Would be nice to have an extra battery pack. Did not see anywhere on website to order

Works well; on medium setting lasted for 4 hours. Neck is a bit tight but overall very satisfied. Haven't washed it yet so can't comment on that.

Great product Great service and satisfaction

Bought this for my wife who is always cold. We live in Indiana and from Oct. till about May she's always cold. So after buying this we had gone to a friends house for a cook out in mid Oct. perfect time to trying this out! She was warm for once while we were outside!

Gets chilly up at higher elevations here in colorado and this shirt hits all the right spots so the chores aren't so terrible.

Got this 2 days again and immediately charged the battery to full. The front feels a little hotter unless I'm sitting down and leaning on the other panels. I lived in the cold for many yeears and couldn't imagine going without this now!

Definitely keeps you cozy, was out for 2 hours in 30 degree weather and only needed medium power. Excellent battery life but depends on temp level.

This shirt is so versatile! You can wear it on its own indoors, and underneath just about anything outdoors! You can barely feel the battery on your side

I don't really have anything bad to say about this baselayer, except it could definitely have a longer battery life

A heated base layer is perfect because it adds heat to an outfit you already have and love. No need to replace your favorite jacket with a heated one when you can just buy an extra layer to put underneath

I'm so happy I have this shirt. Really helps to keep my tight neck and back muscles loose and the heat is pretty nice, too!

I like the zipppered pocket for the battery. You can hardly tell it's in there. I wear my polarfleece over this shirt and it keeps me toasty warm for hours.

Impressive heated base layer shirt. Highly recommend to any lady who is cold.

I bought these along with the matching pants to wear under my Klim moto gear when I'm on my 1200GSA. They keep me really warm and I'm not tethered to my bike.

The battery is a bit big and keeps me from tucking in the shirt like I'd like to, but the heat is amazing.

Just gong to keep this simple--this is great, lots of heat, buy it!

I just washed my base layer shirt that I got last fall and it washed up nice and still works! Don't be afraid to wash your heated clothing (if the instructions say you can)--nothing terrible happened! I wore this M-F for 8 hours a day and 5 months straight and it never let me down.

I love mine so much I bought a second one, so when one is in the wash I can still be WARM. This shirt has some amazing heat in it.

the battery tucks away neatly into a zippered pocket at the waist/hip. The zipper itself is a bit bulky and you can't easily tuck into your pants, so I kinda finagle the hem into my pants so that the battery is still above my waistband. If I wear a tight shirt over the top of this, you can see the battery bulge, but I don't care, 'cuz now I'm warm. ;-)

took a couple of size exchanges to get the right fit but now I'm happy and warm. I work in a deli and am constantly ducking into the fridge and freezer for stock so this shirt keeps my shoulders and neck nice and warm for my shift.

Can be used for some maany different things, for running, hiking, skiing, walking the dog, hunting, fishing, or whatever else you do outdoors

Comfortable and WARM. Simple as that.

I am a birdwatcher and photographer, and this baselayer is now an essential part of my gear. I am out very early in the morning before the day gets warmer and just turn the heat off once the sun warms me up. Even during the day its an extra layer to keep me warm

A heated baselayer is such a great idea! Very soft and comfy and keeps you very warm

I bought this top when it was on sale and loved the heat so much that I've bought a second one at full price. That's how much I love it! At first I thought the heating cables would bug me, but I don't even notice them now. You have to get this shirt, it's wonderful!

It's gives you the same amount of warmth as a throw cover but with the convenience of letting you move your arms around better.

Love this shirt! When I wear this with the jacket and turn on the heat for both, I'm in heaven!

It's the best shirt I wear when it gets a bit too cold for that day

the shirts a bit tight. I used the sizechart but I'll return it for one size up.

fits nicely for a base layer and keeps me warm

warm and long enough that your stomach and hip area stays covered

I gave this shirt to my cousin for Christmas and she seemed happy with it!

Got this along with the batteries and pants. The heating to this is enough to keep me warm for several hours in a day. The material to the shirt never makes me feel sweaty or itchy when I wear it for long periods of time. I'll get another one as soon as I can.

My whole front and back felt soo warm when I pressed the button to heat them up!

Pretty stretchy. Can be layered underneath with sweaters or other shirts without being noticeable.

I am an avid skier and already owned the a jacket and snowpants I love, so I bought the heated baselayer shirt and pants and they keep me nice and warm all day

I'm always cold at the office so I thought a heated base layer would keep me from drinking coffee all day long just to keep warm. This shirt centers the heat around my shoulders where I really need it. A+!

I like that the heat is on my chest, and also my back. Keeps we veeery warm

I wear this baselayer when I go hunting and it keeps me warm like I expected it to.

I had a previous version of the top that had a velcro closure for the battery and it was a pain in the a$$. I decided to buy a new shirt when the old one busted a seam on the neck (totally my fault--I think I caught it on a tree limb or something). I was really happy to see that the battery pocket now has a zipper. veryy classy looking and no more velcro snagging on everything. the heat this top puts out can't be beat. wear a t shirt underneath and them a fleece over it and you'll be happy as a clam. Two big thumbs up. I think i'm gonna buy the pants too.

I got this base layer for my girlfriend when we go out skiing to keep her on the slopes longer, now she’s got three more and we’re about to get a pair of the pants too. This will be awesome and more colors too

Your heating system is uniquely designed and comforting. Thanks

The design of this baselayer compliments my body shape and I love wearing everytime I go out to jog.

This was wonderful. I wore it for skiing under my jacket and another top. Much better than a bulky vest. It runs large. I strongly recommend buying a second power pack. I got just about what was predicted for the one power pack. I had one I thought would work but NO. It was a very cold day and I ran out of power towards the end. This will also be handy for football games, etc.

Love this product. The infrared heat it actually works as advertised and stay warms.
