Awesome

I love the Coefficient Quarter Zip. Great for cool weather with a t-shirt, and also as a layer.

Buy before their sold out!

A must have sweater! For run, for trad and ice climbing. Best all around sweater in years. I fit better in the xs man ( I’m a lady wearing XS women. ) Shoulders a bot larger and it stays fit at the bottom.

Awesome hoody!

Breathable, stretchable, and warm... this hoodie is perfect for hiking during the shoulder seasons in Virginia. Fit: The medium size has no extra room and I am 5'8" and 143 lbs.

Amazing fit

I have a lean muscular build and am 6'1" 160 lbs. This fits me perfectly and is very cozy/warm while still being breathable and light.

Coefficient 1/4 Zip

I own several mid layers of this realm from many diff companies. The Coefficient ranks up there with the best in looks and function. The Co was my first Black Diamond purchase. I'll be sure to buy more gear

Love the fit

I have a full zip version of the same item and it is my go to for backpacking and skiing. The hood is great under a ski helmet. This one will be used for running too. My favorite Black Diamond product.

Great fleece for climbing

The old standard here was called the R1, from another brand. I've been looking at all the fleeces lately since I'm at the stage where I've trashed a lot of my gear and starting to replace it. The BD coefficient has what others done, great fit, good hood, an actual zipper guard (unlike the r1). It's fantastic. 2 gripes: if my zipper goes down all the way it sticks, I'll probably contact warranty since it has done this since I got it new, and I think the material could be thicker given the price. Overall, there's nothing better that I tried...and I tried a lot of them. Enjoy! 6ft2in, 205lb broad shoulders, xl is perfect.

Great Fit!

I bought this as a mid layer. It fits great and snug, not too snug over my first layer. Lots of stretch and the hood fits great under a helmet. Also like how it zips up high and creates a mini face shield. For reference I'm 6' and 150 lbs, I bought the medium. Much recommended!

Great addition!

I have the coefficient lt hoodie, which is my favorite, and I wanted a backup. This is heavier and feels more durable. The slim fit is why I like it so much. I’m 6’2” buck 70 picked up a size Large. This has great arm length and not boxy at all. Will last forever I’m sure.

Multifunctional and quality

A great piece of kit to bolster up as a layer on a cold day and wear as an outer on a chilly morning. As valuable on a belay as it is around the campfire. A bit snug around the armpits, but that is typical for my body in BD clothing.
