Rated 2 out of 5 by from Too Long and Not Really Blue Both the sleeves and top were too long for me. The model is shown with the top ending at hip, but it completely covered my bum. I'm 5'1 and 105 lbs and XS usually fits me perfectly. Also, the colour... it looks on all the screens I used like a nice medium blue, but is really a heathered magenta and teal mixed together to form a blue-ish colour; quite clever but I refuse to wear these colours as a general rule because they are so prevalent in women's hiking gear and yet so rare in nature (olive green, ocean blue, rock grey, these are the colours that let women blend in with their environments). Plus, the inside is white, which just looks odd when you open the collar.

Rated 3 out of 5 by from Almost unpleasantly warm. Fit/Shrink Issues I bought this with the intention of using it as a sweater over day wear as well as skiing clothes.I like my clothes to be multi-purpose to cut down on how much I have to pack. However, this zip-up is WAY too warm to wear even in a cold house/cabin. Wearing it just long enough to harness the dogs is enough to make me feel vaguely nauseated. While it's softer and prettier, it reminds me of the polypropylene of my youth, which isn't exactly praise. It also has fit issues, the hips are COMICALLY narrow, and the waist is cut comically long so as you move, the sweater slowly rolls or bunches up around your waist. It's not a flattering look, and while washing it shortened it significantly, and I have a long torso, I still have puddles and rolls around my midsection. Will I use this? Yes, on those brutally cold days I have to go outside.But for the price, I really wanted it to be a better multi-use sweater with a flattering fit. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Amazing Quality and Warmth I am absolutely loving the quality of this half zip for my early morning running before the sun comes up. The top is so comfy, SO SOFT and I actually like that it does not have thumbholes because the sleeves are just perfect as they are. Loving this new top. Wish I had purchased two!

Rated 5 out of 5 by from My move from the south I am just learning that cold here in Oregon is a hole different thing than cold in the south. Lol this top along with other I will be getting are teaching me how to layer my clothing so I can be more prepared for all kinds of weather.

Rated 5 out of 5 by from Cozy and comfortable I first used this on Mt. Jacinto peak through hail and snow. It definitely kept me warm. I did have an Icebreak tshirt underneath. The material had a nice cozy feel to it and love the look. It was breatheable and lightweight.

Rated 5 out of 5 by from Perfect fit and warmth Fits like as glove. Comfortable and warm. Really like the half-zip to manage warmth at the neck. Nice pattern, looks great. Perfect base layer or 2nd layer!
