Stays very warm! Only problem is that it is very slim so it wiggles around in the standard cup holder in my 15yr old car.

This jacket is very warm and is perfect for those extra cold days ! The only thing I didn't like was that it wasn't sewedas gtood as I thought it would be so i resewed some of the pockets myself and I wear it in 20 below weather! The hood is a good attachment and I can remove it for those warmer sunny days of March!

Great product!  Wife loves how warm it keeps her!  No complaints at all.

Excellent heat generation.  The only thing I don't like is it's too "slippery," so the covers slide off if I move about too much during the night.

My big worry was I've read a lot of the new electric blankets are too weak, and warm only a little.  This one does seem to generate plenty of heat.

My googling around is what led me to Sunbeam as the one brand that still gets very warm.

Keeps ands warm, but the elastic band is quite annoying to deal with.

I love the warmth of this hat - I've been wearing it in 0 to neg 10 degree F weather and it kept my head very nice and warm which was my primary goal! So I'm happy with it. Only complaint is that it's bulkier than it would need to be - makes my head look like a weird mushroom. :)  The cable design sort of makes it look lumpy as there's extra fabric on the top part of my head. So not particularly flattering but it is comfortable.

Love it, keeps my head warm, only problem is that if it gets caught on something it creates a hole pretty quickly

I have been using this heating blanket now for 4-5 months. Still great Heat output. Previous blankets would not keep me warm with setting on high. I keep the setting on about 4 and it keeps me warm all night. Never before has any blanket performed as well. Micro-Fleece is very soft and wiring isn't noticeable. I would buy it again.
The only problem is that this dual blanket has two power plugs and at the bottom of the blanket there is one plug for each side, it would be nice if the plugs to the blanket had a locking mechanism so they won't come disconnected. My previous blanket had two small plastic clips that went down the sides of the plug and locked into place, they were easy to unhook by hand.

Holy moly, trust them when they say +20F sleeping bag! It's pretty roomy, although if you roll around a lot the flannel inside tends to stick, at least it did to me... lol. But when I unzipped the entire side and sort of used the top as a blanket, that worked pretty well and it was plenty warm! That's why I had to unzip 1 entire side. The outside temp was "only" in the upper 30's to low 40'sF and this bag was keeping me a little too warm until I opened it up a bit. The quality seems good (though I've only used it twice so far), and it DEFINITELY does its job insulating.
It was a little tough to get back inside the carry bag. Rolling it up and stuffing is probably a 2-person job. But what a great bag!

This headwarmer did it's job perfectly. It kept my ears warm all day while outside in 15 degree weather. It was tough wearing jbuds earplugs though, they were forced way too snuggly into my ears. I would still give this band 5 stars though!

It definitely keeps your liquid cold even in super hot weather. I left it in my car during a 95 degree day in the middle of a heat wave and it was still cold the next morning. The only downfall is that it leaks and does not fit in the cup holder so I have to lay it down so it ends up leaking. contemplating on buying another because I have read other reviews on similar products and they have the same issue. I wish it had a different lid that did not have the straw in hopes that it would not leak.

Keeps warm enough, even if not for really cold days. I love the fit but agree it is tight so definately not a one size fits all!

My husband loves it. He's had it for about 2 years and it's holding up well. He wears it when he needs a heavier hoodie and it keeps him very warm! My only problem with it is I thought the "wool" material would be in the sleeves as well. We were really looking for that feature and were disappointed. But the sleeves are still quite thick and keep his arms warm. Happy with it overall, though!

Bought this for my hubby on long car trips and he likes it!  Works pretty well, but the fabric makes it a little warm-that was his only complaint

very warm and comfy, looks good, only problem is it collects dog fur, but that's their fault for being fuzzy! im 5'11 165 lb and the large fits very comfortably.

amazing comfort, and I've had for a few months now. THE BIG DOWNSIDE THOUGH, is that IT RETAINS HEAT SO BAD!!!! I've been contemplating whether it's the AC or is it me, but no matter how low you drop the AC, in my case to 73 degrees, you'll still feel so hot at night. I wish they added something to it to make it cooler somehow. To buy another layer of a cooling gel would be another $100 which is a little pricey for me at the moment.
