"This is a great jacket for cycling, hiking, etc. when it's too cold to go without a jacket but not cold enough for something heavier. It's somewhat fitted and a little stretchy so it moves with you. The 'waffle' pattern of the fleece keeps the jacket from getting sweaty without giving up as much insulation. The water-repellent finish will keep drizzle from soaking in too. I mainly use this jacket for biking in 40-50F weather and it's perfect."
"This is both comfortable and good-looking. I layer it over a mid-weight merino base and stay warm on uphill laps in temperatures as low as 5°F."
"I bought this as a present for my boyfriend who just started climbing. The color is amazing and rich. The fit is incredible, we have previously purchased some other jackets from other brand and the Medium tends to be too small, and the large too big. But I think this one is the perfect true to size hoody. The fabric is amazing for mid mountain trekking and has a polar covering in the inside."
"I use this for rucking, fabric is very sturdy and has enough flex to allow free movement when stretching and exerting. Best part is the fact it’s like a thin jacket so you have the pockets to keep phone and ear budss in a thin layer that doesn’t get in the way. Only minor issue I found is I should have ordered 1 size bigger. I ordered my normal size for BD gear and it’s a little smaller than I normally like. But I like the other aspects of it so much I’m getting used to the fit rather than return."
"This is a really solid, comfortable fleece hoodie on the lighter / light + / medium side of weight. Light enough to send in during the fall, I prob wouldn't take it out on my coldest winter days but it's a great cold season mainstay. I love the purple color! great quality as usual for BD"
"This jacket is awesome and I highly recommend. It’s been the perfect touring layer thus far! The sleeves on it are slightly long for my arms so it works well with skiing but they kind of get in the way of climbing. I have just had to roll them once or twice but it’s not a big deal"
"I got this hoodie on a Black Friday sale and I have been wearing it regularly for four weeks now. It's a great lightweight hoodie that keeps me warm on my evening walks when the temperatures are in the mid 40 degrees and it also works well and a layer underneath my winter jacket when the temperatures are in the 20's. The fit is on the slimmer side so plan accordingly when ordering. I purchased this to wear in cooler weather for golfing and given the stretch of the material, I think it will work perfectly for that. I am very happy with this product!"
"Great midlayer zip hoodie. I like the elastic cuff, hem, and hood. The zip chest pocket is a great feature which a lot of hoodies in this style don't have. Overall I'm very happy with this purchase."
"The Coefficient Storm Hoody is a legit mid-layer option. It provides solid heat, holds up to light wind if wearing as an outer layer, and breathes very well. I’m a medium and it fits accurately. Snug, but not form fitting tight."
"I washed this item once under normal conditions, and there is widespread pilling all over it. It looks a bit ridiculous. Fit is a bit boxy and short in the torso. I purchased it on sale so cannot return it. It will go on the donation pile. I was hoping this would be similar to a Patagonia techface but it is nowhere close. What a waste."
