Disappointing decline in quality
"For a sweater of this price I would expect a decent zipper. The same sweater from 4 years ago has a nice metal zipper, now it's small cheap plastic that gets stuck."

"I use this in the cold office when the air conditioning is turned down. Also looks great with a nice pop of color. It is also great for travel. I never get too cold or too warm. I love this hoodie and would buy another one in a different color."
— GBranger (5/5)
"I have purchased this hoodie (in many different colors) 7-8 times since 2021. Every year the quality goes down. Now the zippers feel like they belong on doll clothes. At the discounted price it is still worth it. I will never buy one at full price. The fabric is thinner, the stitching is less tight and as I said the zippers are just waiting to break."

"Initial review, well made and comfy jacket. I have slightly longer arms so the thumb holes are too high for me. Not a huge fan of the scuba hood, but got this on sale for a pretty good price."
— Mark (4/5)
"I bought one of these in 2021 when I moved to Tasmania and wore it almost every day since. Loved it. When the thumb-holes began to wear away I didn't hesitate in buying the same again. Except it turns out you can't buy the same again. The design is the same, but the ""merino"" fabric on the new hoodie is noticeably thinner than on the old one that's been through many wash cycles. I got so chilly wearing this I'm now wearing the old one underneath it. I'm sure somewhere in icebreaker there's some marketing monkey who got a promotion cutting costs on the ""wool"" that went into this travesty. Congratulations, genius, I'm never buying icebreaker again."

"I've been wearing these for a lot of years. Im about to buy my fourth one. As I write this, I am still wearing the same one I bought originally 10 yrs ago or so and have the others in my rotation still as well. Yes, they are worn, frayed, torn at the elbows, ripped at the wrists but it is still 100% my FAVORITE thing to put on. Length of sleeves:perfect. Hood: Perfect fit. Waist length and size: perfect. Feel: perfect. Fit at shoulders and biceps: perfect. Comfortable as AIR. I am 6'3"" 200# slim long athletic build and wear an XL"

"Very versatile, wearing nearly everyday since purchase."

"Used to be One of the best hoodies, have two of them previous version. New version with CHEAP zipper and also material is thinner. Quality has degraded from five star to two star, would recommend avoiding it unless getting it a great deal!"
— VJ (2/5)
"The website pic looks great, nice sheen or luster. The actual fabric is more dull; and the start of some pilling. I'm wondering if the pic is misleading and or I received a slightly used item."

"Pockets could be Lined."
