Remember 1995, when the Dow crept above 4,000 for the first time ever, the Men's Icebreaker Original Zip does. That's the year it was introduced into the Icebreaker lineup, and it remains as popular today as it was then. Part of the Sport Sweaters line, the Original Zip is knit with a dense 320 g/m2 weight wool and sports a ribbed collar and thumbhole sleeves to keep the gaps closed and the warmth in. Set-in sleeves, which are slightly more refined in fit, join the regular fit body and make for an exceptional layering, or outer, piece. The side seams have been moved forward to reduce bulk and the potential for chafing, and finishing touches include the tonal embroidered logo on the left chest and the discretely placed pip label. Calvin and Hobbes may have ended their run in 1995, but the Original Zip for men from Icebreaker was just beginning.

Keeps me Toasty
November 01, 2010

Well well well. The original Zip is a phenomenal wool top. Really nice and warm. I appreciate more of a relaxed fit as opposed to a body fit especially with the thickness of this top. If you want a beautiful sporty warm wool top then IceBreaker Original Zip will not disappoint.

Pros: Great design, Build quality, Lasts forever

Good Sweater, Boxy Fit
February 18, 2012

I have a couple other Icebreaker sweaters that I really like (fit, comfort, quality), so I decided to give this one a try b/c it had a little less athletic appearance. But the fit was what I would describe as "boxy" for Icebreaker. It was too loose for me in the torso and the shoulders were really squared off. I decided to return it and stick wit the Icebreaker Sierra sweaters I already have.

Pros: Build quality, comfort, wool, Cons: inconsistent fit

Icebreaker v. Smartwool
December 11, 2011

I prefer Icebreaker over Smartwool as to durability and otherwise. Specific to this product, the Icebreaker 320 gram products provide greater warmth than anything I've experienced with Smartwool.

great wool product
February 12, 2012

Icebreaker has done a fab job of working with Merino and creating a product that is both stylish and comfortable. I am confident it will be durable, but will let you know in a decade. Reckon i will buy more Icebreaker thru Altrec in the future.

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

Good but not great
July 30, 2012

I purchased the Original Shirt and also the Sierra, at that time they had same price. Wanted the Original as it was 320 while the Sierra was only 260, however the Sierra feels warmer than the Original. As the Original has a pretty look, I think it will be useful for everyday use at not very cold places.

Icebreaker = The Best

This is an amazing shirt; Warm, dry, rugged, and looks great. I always wear it outside to keep me warm, but it looks great with a pair of jeans too.

Great Shirt
January 09, 2012

Very rugged and thick shirt, pretty much like a sweater. Excellent fit, no itch at all. Great layering item under a jacket or just by itself with a t-shirt underneath when warmer.

Original, Simple, Perfect
January 21, 2011

I can see why Icebreaker has become so popular by the standards they set with their original sweater. It simple in design, very comfortable whether wearing around the office or out for dinner, and really well made. This my "go to" sweater. It's perfect.

Pros: Great design, Build quality, Great value
