"As a ski-patroller in Montana, I need to be ready for sub-zero temps in the mornings and bluebird conditions in the afternoons BD's Coefficient LT Quarter Zip Pullover is the shizzle! Surprisingly the warmest mid-layer I own when zipped up, and the perfect weight unzipped. Absolutely love it!"
"My FAVORITE base layer. Great moisture wicking and warm enough but not too heavy for a base layer."
"This quarter zip exhibits the impressive quality and fit I have come to expect from Black Diamond. Great base layer for cold and cold temps. It is a snug but not tight fit. which I prefer in my base layers and it moves comfortably with you. Recommend without reservation."
"Never leave home without my fleece perfect for evening climbs"
"This mid-layer has a ton of uses. Last winter I used it on its own for higher aerobic activities in colder weather, or layered it with a compression base-layer to add some extra warmth on colder chair downhill ski days. The quarter zip is ideal for dumping heat as it extends further down than most quarter zips. The BD tag says “slim fit” and they mean it. It’s very tapered at the waist and fits snug through the chest and arms. Most BD items I’m a tried and true medium but with the slim fit designation I went up one size to a large but I probably could have gone up to an XL. Make sure to size up."
"A little bit thinner than I expected. The fit is slimmer than I expected, so I would size up if you want to use this as a mid-layer."
"This is from fitting, more of a base layer, with mid thickness, great for winter super breathable, far more durabls then any of the muppit alpha gear"
"I was hoping this would be the same fit as the hooded pullover, totally didn’t factor in the lighter weight of the fabric and assumed it’d be similar. Too light for my use case, but still a great piece! Definitely stretchier than the burlier Coefficient, so I could size down!"
"a little tight for a large."
"Very nice for first layer under windbreaker. I suggest ordering one size larger. Slim fit. Always dicey with BD"
