"Quantum is always terrific and we couldn’t resist buying another in this colour. It is lovely."
— Morah F. (5/5)
"Great thin jacket yet warm and comfortable to wear. The only issue is that the fabric seems to wear out quite quickly and for the price it has I'd have expected some more durability (I've only had it for a couple months now and I give it a light use)."
— Miquel R. (4/5)
"Nice unit. Great fabric. Fits nice overall, if slightly long in the torso. Fit is slim. Strongly dislike the chest pocket. Would buy 10 more if this was removed."
— Daniel S. (5/5)
"Good quality and snug fit, good for layering. Not very thick or heavy. Comfortable."

"Quantum is the first hoodie i boight from icebreaker back in 2010 or so. It has changed a little through the years but is still my favorite sweater with or without the hood."
— Cole (5/5)
"Je suis tellement bien dans ma petite laine icebreaker que je m'en suis procuré une deuxième, histoire de ne pas m'en priver une seule seconde lorsque le temps est venu de procéder à un petit lavage à cycle délicat."

"My partner and I each bought these Quantum long sleeve zip jackets in black. We loved the style, fit and weight but returned both of them because of the white Icebreaker logo on the sleeves. We found it really reduced the otherwise classy look of the jacket. Such a shame. I bought one in green that I love but the logo was also in green so it wasn't so obvious. They should definitely correct this flaw in my opinion. Even if it was in grey on black it wouldn't be so obvious."

"Scores highly for all my needs 1) I use public transit and I am often in super cold rooms to work. This is simple enough to be used in the work environment. 2) Frequent traveller, this is 260. The competition uses 150. Hard to believe you can be comfy in those freezing airplanes. I use it as my winter coat on departure day when I go somewhere warm, I just wear a windbreaker over it. If it works for Montreal, it works anywhere. 3) this is what it was designed for. As a mid layer for winter activities. Great for touring skiing, you just put your coat or shell when you get in top. It depends how cold it is."

"Repeat purchase of the Quantum jacket which is in heavy rotation all year long. Great durability considering the amount of wear it gets, and have not been able to find a better equivalent over the years. Please never discontinue!"

"I was a bit disappointed since the quality has gotten worse. This is third icebreaker( Merino 260 Quantum Long Sleeve Zip Jacket) in the past 20 years. The elbows always wear out on my husband. He said the original zipper was medal and now it is plastic. As soon as my husband opened it for Christmas, he couldn't pull the plastic zipper up, and it seemed defective. We need to exchange it."
