ARRIS 5V USB Cooling Jacket, Air Conditioning Jacket With 4 Fans, UV Resistant Cooling AC Fan Jacket

Yes, this jacket does run maybe a size small, so you should size up, 2 sizes up would probably give a lot of extra room for air, but one size up works. The jacket blows are around inside (and into the hood when you put that up). I got it so that I wouldn't get sweaty on my bike rides to work in the morning. This probably won't be super effective in 100 degree weather since it is just blowing around air ad doesn't have a cooling ability, but was good today in the mid/upper 80s. Just sit in a hot room with a fan on and that is the effect you can expect. It certainly makes more days tolerable as outdoor days. It is a bit annoying that the battery pack is a separate purchase, but other than that, their photos are 100% accurate and it does what it says it does. I will update this in the summer to let y'all know how it does in real heat.

Blows around hot air! Don't waste your money!

It does do as advertised but the 2XL is more somewhere between a large and XL while the XL is more of a large medium. If you are tall it's not long enough and if you have a couple extra pounds the air probably won't circulate well. Same with weighing down pockets with things, too much weight in the pockets prevents the air from circulating around your upper body. If you are a small person and don't have much to carry then don't miss out it's pretty good. If you aren't so little one way or another, might want to give it a pass.

This jacket works pretty well. I wear a huge plastic custom fitted brace that gets very hot (since it is summer). This jacket does keep me much cooler. You just have to keep it zipped up all the way. I look Iike a big puff ball, but I don’t care!

I purchased this jacket before Our latest camping trip this weekend. It has been very hot here in Illinois, and our camping area was secluded with trees surrounding us, so there was no breeze at times. The other guys were miserable in the afternoon/evening, I had my jacket on, and it’s like being in a breeze whole time time!! Just the fact that the air is moving over your torso, is enough to keep you cool!! I never would have thought it would work so good, but it did! I let two of my smaller friends try it on and they both loved it.One of my friends actually ordered one for himself when we got back into cell phone range. I would highly recommend this jacket, it does what it says it does, and well worth the money!

*** UPDATE *** Jacket and fans have been working great! Great way to keep cool. Bumped from 4 to 5 stars ;) - Original review Purchased this to see if it will help keep me cool during hot weather. The fans are easy to remove for washing the jacket. The air rises and exits around the neckline when the jacket is zipped up so you get a breeze around your face. You'll need to supply your own USB battery pack to power up the fans. I use a USB extension cable so that I can keep the battery pack in my pants pocket instead of in the jacket. Looking forward to trying it out on some hikes or when I am out flying my drone.

Does not work as advertised. Only pulls in hot air from around you, and the pockets block 2 of the fans.

Works grate for spring
