I am an avid golfer and live in SC, but even in the south we get chilly days during Dec, Jan and Feb. This vest is AWESOME. Sleeveless to allow for freedom when swinging a club, and three heat settings to keep you toasty warm on the course. It's not just great on the course, it is great for walks on chilly days, or for any outdoor activity where you want to stay warm. Heat at the neck, upper back and front of chest, is perfect. The fit is as expected. I wear an XL and the XL fits just right. Rechargeable battery pack connects to a cable that is attached to the vest and tucks away in an inside pocket. Great value for the price.Wonderful as long as it’s working… good luckA friend of mine ordered a vest from Amazon and I liked it so much, I decided to shop for one for myself.The one I ordered is wonderful, warm, fits well and at a great price on the day I searched for the vest. I have worn it walking and it is great especially for this time of year when the weather is cool part of the day.My husband wants me to order him one as well.The fit, looks, comfort and functions are perfect. The only thing is that the standard battery has issues charging. I have another that fits so all is well.The vest works pretty well. The battery pack worked for one day. So I use one of my own now. The vest is annoying to use when it turns off you have to re-plug it back into the power bank before it’ll come back on. But otherwise it’s pretty warm. I will say that the only heat I really feel is the neck of the vest. I probably wouldn’t buy this model again.I have two brands of heated vests, this one fits much better than the other one (which was twice as expensive). Both came with battery packs, this one arrived without a wall adaptor, but did have the charging cord. It fits in any USBcharger port. Love the vest!I love the panels in the neck. The neck section warms up nice and is great for cold days. The back and front panels are slightly warm. It helps some. Nice layer. I wouldn't buy a heated jacket from this company. I can wear it as a layer so I am keeping it. Not my best purchase. It is also not my worst purchase--hence the rating of a 3.This is very well made and I especially like the high collar that keeps wind etc. out. The battery charged quickly and is not over big/heavy. I wore it in 30 degree weather with just cuddle duds under and a waterproof jacket over and was warm enough. Am curious to see how warm it will be in colder weather. One thing for me that you might want to consider is that arms will still be cold..I expected that but just in case you are not thinking about that aspect. I'm happy to be warm when I do morning dog walks.
