"After just a handful of washes, this hoodie is showing extreme amounts of pilling over the entire area. I submitted a warranty claim, but was informed I need to cover the cost of shipping the hoody to Salt Lake for "further evaluation. " From Canada, this shipping is going to cost almost as much as the hoody is worth. The photos I submitted on the warranty claim clearly show the issue, so it isn't reasonable for me to pay this shipping cost and a refund or replcement should be issued."
"A very warm jumpsuit, the perfect size for a second layer, the perfect hood"
"This is a good 4 season base layer, with a hoody and zipper. I tend to think of it as layer 2 in a 5 layer system for mountaineering. It's durable, stretchy. Fit is good I'm 5'11 205lb and large fits well. Easy to layer over. Grid fleece is reasonably warm given how thin it is. Used it daily for a 7 day whistler skiing trip, no complaints."
"It's a great mid layer that I'm looking forward to for cold days of touring or chilly days skiing the resort. Fit is a little tighter than expected, if you're between sizes I'd recommend sizing up."
"It's a tad thinner than desired (can see through it when I hold it up to the light) but does exactly what I intended: holds a hat on my head and a phone against my chest while I sleep. Pretty warm for the weight. I fully expect this to be part of my kit for a long time."
"I’ve worn this piece ALOT over the last year and a half. It’s not worn out yet but I got another one just in case. Awesome base/mid layer that covers so many seasons and activities."
"Perfect weight for a range of active activities anda nice long cut. I appreciate the full length zipper for venting and layering, but the zipper itself is a little janky and often requires two hands. Could be improved with a burlier plastic or higher quality metal zipper, but I suspect this would change the weight and cost. Elastic on the hood could be a little snugger as well. But a solid option for the price."
"Great fleece mid layer. Very comfortable and a great snug fit for layering. Works good as an outer layer on mildly cold days that aren't windy. The one thing that can get annoying is how high the zipper goes up to your chin."
"my wife and i both picked up this hoody as a lighter mid layer, and on a hunch, that we might be able to eliminate some bulky accessories- in particular, our balaclavas and neck gaiters. and our hunch was correct! now she can layer with another mid layer over this one, and her neck and head under the helmet stay warm and free of snow on cold days…and the athletic cut looks good on our athletic middle-aged bodies!"
"This is the piece I've been waiting for to complete my layering system for snowy winter pursuits. It is super stretchy, has the right length sleeves for reaching overhead and out, a full-zip for dumping heat / moisture when needed on the skin track / boot pack, a comfy hood and flexible / stretchy neck that turns with me and doesn't get in the way of looking around (and up) when totally bundled / zipped up. I LOVE it! Another terrific piece from BD and perhaps the final missing piece in my layering puzzle for winter! Yay! Great job, team! :)"
