"I own a Coefficient hoody from about 7/8 years ago and loved it, so I bought this version. Sadly, it's really poor. Brand new it's thinner than the old version and after only 4 or 5 washes the structure of the gridded fleece is breaking down making it worse. It's a shame as I own lots of fantastic BD kit, but this always seems to happen when companies get bigger, quality goes down."
"Great quality, great fit, great look, very happy…. ."
"Great product!"
"The fit and functionality as a midlayer for split boarding is really good. I am 190cm/86 kg and bought a size L. Very satisfied"
"I have a coefficient hybrid in M, which fits well, but this 'grid fleece' is much tighter in the body. The fabric is actually closer to a thin 'tech fleece', sort of like a softshell, which would be OK in itself if the jacket had fitted me. I would regard it as being a hardwearing but thin grid fleece. I have tried different shells and midlayers now from BD and there is not enough consistency in the sizing for me to carry on purchasing any more products. Specifically, some size M have been tight in the chest but the size L, when I reorder, are huge all over. Colours are also a bit boring for the mountains, in my opinion."
"Definitely my favourite fleece-jacket!"
