Blazewear Heated Sportsvest: Lightning Review
The Price: $US139
The Verdict: OMG warm! Although not as fitted or high quality as the Ardica jackets, which have padded battery packs and clothing designed by people who specialize in fashion like Mountain Hardware, Blazewear isn’t meant for the same purpose, and is a lot more affordable. And very warm, as I said!
Wearing a thermal I took some heat gun ratings of my core and the vest at settings 1 through 5. Setting 1 is very toasty, and lasts about 3-5 hours, with 5 lasting far less than that. Here are the ratings and my level of comfort.
Setting 1: Vest temperature of 43.3 degrees C, skin temperature at my chest of 33.9. Warm
Setting 3: Vest temperature of 54.4, skin temperature at my chest of 35. Slightly sweaty, body trying to cool itself.
Setting 5: Vest temperature of 65.6, skin temperature at my chest of 37.2. Uncomfortably warm.
I took these measurements at room temperature, after 15 minutes on each setting, but you could feel the heat changes within seconds. The higher settings seem unnecessary but in cold environments, I’d be glad to have them. The extra heat also works to penetrate thicker clothing, too, like shirts and sweaters. The vest’s three heat panels are on the back (a large rectangle) and on the flank of the zipper on the front (two smaller strips). The heat was sometimes spotty, on account of the fit being not exactly snug. In fact, the vest’s fit is a little on the big side, so good for larger Americans. And the synthetic materials seemed to breath well. When the vest was off, it offered little or no additional warming, fwiw, so you won’t want to depend on this jacket when its powered down.
Although Blazewear has outerjackets and gloves, I tested this one because it seemed to be the most capable of being used with your existing jackets and clothing, which you’ve probably chosen because they also look nice. The vest is meant for sporting, but I declined to use it for snowboarding simply because of two reasons: the battery pack rests on my hip, and would be very painful to fall on, and although it would be nice to adjust the vest’s heat output electronically as I went from the chair to moving, the control are on the battery, which is in a pocket and inaccessible. I wouldn’t be willing to unzip and reach inside two layers and a pocket to do so. If I was going for an outdoor activity jacket, I’d get an Ardica, but I’d have to spend a lot more money, too.
The cost, though, is very reasonable. And I’ve fallen asleep wearing it on cold days on the couch, wearing only it and no blanket. For those who are cold and want unbeatable warmth that is electronically generated, I’d recommend this vest for those on a tighter budget who want to wear it while commuting or hanging around.
