Great fleece for climbing

1 year ago

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 and warm

6 months ago

I normally wear a size small but ordered this in a medium and it fit perfect. Not like some of their other product in terms of fit. The material is relatively thick so it works well for medium pace running with a t-shirt underneath in 35 degree light wind sunny conditions. Also a tread mid layer if using a windproof insulated shell in higher alpine cool weather with wind and low intensity activity.

Really great layer

6 months ago

I needed the right layer for splitboarding becuase I get really hot quickly. This has been a really nice addition. I'm 5'11" and 185lbs and the large is form fitting. I'll wear a smartwool t-shirt underneath and that is it. It kept me warm when I needed it but when I zipped it all the way down I was perfectly cool.

Love the Coefficient Quarter zip!

2 months ago

I’ve had multiple coefficients over the years. They are my go to for resort and backcountry skiing. This is my first one with a hood and I wish it was available without one. I’ve always enjoyed the Polartec fleece because it is so warm and it breathes well. You just can’t go wrong with the Coefficient!!

Bomber

2 years ago

BD's Coefficient fleece is super light, super warm, and unlike a lot of fleece out there, bomber. The hood is well designed and the whole set up so good that it's the one piece that always goes along. So good I ordered two more. I'm 5'8" and very thin, the small is a perfect, seemingly custom, fit.

Great Fit!

1 year ago

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!

2 years ago

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

2 years ago

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.

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
