Rated 4 out of 5 by from A nice piece of gear to add to your collection! I purchased the older version 4 years ago and I loved it. It was an indispensable piece of my wardrobe. I loved everything about it, but after a few years, the wear and tear were taking its toll on my favorite hoodie. The new Quantum has some improvements, such as thumbholes and reflective stripe along the front zipper, on the back, and the more form-fitting cut. The only drawback compared to the old hoodie is that it is much lighter in weight. The older hoodie was more of a proper hoodie, while the new one is closer to a mid-weight base layer. I like my new hoodie but I miss the weight of the original. Overall, it is more of an athletic piece than the original.

Rated 5 out of 5 by from Pricey but great Used this sweatshirt on a recent trip to Bogota which can get quite warm during the day but down to 40F in the evening. Overall, the sweatshirt is extremely comfortable and keeps you warm. The three zipper pockets are great and often where I stored valuable while walking (phone, wallet, etc). Very breathable wool keeps you from overheating when the temperature rises. As mentioned in the description, it's a snugger fit but length is great. The zipper is on the left (opposite of most American shirts) and when zipped, the front of the sweatshirt is a bit stiff. The biggest drawback is the price, which will turn off a lot of potential customers.

Rated 2 out of 5 by from Awkward and ill fitting This has the potential to be a great lightweight wool hoodie. I am 5-11 and 175. Medium build. Shoulders and sleeve and length all fit "correctly." A large would be too big. But the way this fits an average body is just weird. It bunches up and sticks out in weird places. I don't have a huge gut nor do I have a six pack, but even if I was ripped and lean AF this would still be bumpy and awkward. I wanted something trim and eurofitting but this is just weird. And I'm stuck with it because it was on clearance. I guess I might be able to use it as just a layer under a light jacket but only if it didn't show. And even then it's just not comfortable

Rated 4 out of 5 by from Good like all Icebreaker gear Feels good, like all Icebreaker gear. I've owned a number of items over the years - I think my oldest item is one of the original pure merino base layer short-sleeve shirts made in NZ. This is true to brand. Feels good, both around the house and out & about. Suitable for active wear, but looks fine for more casual use. Tends towards a slimmer, tighter fit. I'm 187 cm, 85kg, and I wear a Medium. The fit works well for how I use this, as a mid layer, or an outer layer for running, hiking in cool/mild weather, etc. Sleeves are plenty long enough - I often have problems with clothes in general that the sleeves are not long enough. Not so here.

Rated 5 out of 5 by from Want another color! I'm loving this hoodie. I can't believe how soft it is. It's a great weight too. Not too heavy, not too thin. I can see myself wearing this all year round. I got the light blue/red color and I'm loving the color combo. I'll likely have to get it is black or grey also. The fit is pretty true to size. Not too fitted for layering. But also not too loose at the same time. It's pretty long. I've got a long torso and it's longer than expected. But I like that. It'll likely shrink up a little bit over time.

Rated 5 out of 5 by from This is my workhorse... I'm in love with this hoodie, I wear it daily in fall/winter months. Its a great layer, I love the more mesh arm pits so I'm not sweating and still staying warm, the hood is a must for me as I'm a baldy but I rock this thing all the time. I could do without the reflective stripping on it if I had to knit pick but otherwise a great layer when cold out or if its just chilly fine to wear inside to take the edge off or outside if it isn't too cold out. Very versatile I use it all the time, get one!

Rated 5 out of 5 by from Exceptional I purchased a icebreaker full zip with a hood and pockets several years ago. It is a base layer and in the Montana winters I wear it every day. Which is a problem since it does need to be laundried sometimes! I have search everywhere trying to find a replacement with no luck. Landed on this guy and I’m so happy. A little heavier in weight than my previous hoody but very comfortable and warm. Runs just a little big which worked fine for me. I bought the medium and I run between medium and large. Hood, full zip and two zip pockets not to mention the thumb holes. Highly recommended.

Rated 5 out of 5 by from Great for running on low temperatures I use this as a mid layer for running in low temperatures (-9c to 5c). Works like a charm. The zipper allows for quick climate adjustments due to body heat from the run. Works great when paired with a Sprint Long Sleeve Half Zip as a first layer. Hood comes in handy when it is too cold and your ears start to bother you. Perfect cut without restricting movement.
