The Ibex Promise
“I can wear this when investors come to the farm. I can wear this to work in the field.” We’ve heard all types of accolades about the Shak, but none ring more profoundly than its ability to dress up and dress down as needed. 21 micron Merino wool is perfect for active winter comfort, the ponte knit looks handsome even after a full day outside.

We start with the best New Zealand Merino wool to make a range of insulative yet breathable midlayers that outdoor enthusiasts swear by. This exclusive knit is square and dense, creating a rugged yet soft fabric with inherent stretch and long-wearing durability. Our Shak fabric is best used as a midlayer but is soft enough to wear as an expedition-weight baselayer and substantial enough to be used as an outerlayer in some conditions. No matter how you wear it, the performance is unbeatable. Machine washable. 100% Merino Wool

My favorite all-purpose piece...
It's the one piece that I take everywhere...dresses up nice with a pair of khakis. Mine has been snowshoeing with me and the next day at the office. Just get one.

Incredible Product!
I bought this for my husband for his birthday and he hasn't taken it off since he opened it! He absolutely loves it!

Gift made mother-in-law look smart.
My son-in-law has several Ibex products, so I was sure he would like the sweater and he did.

instantly one of my favorite pieces!
It's no surprise that this is the big favorite in the Ibex line...the fabric weight is perfect for sweater or jacket uses...zip the collar up and you're warm, zip it all the way down and you vent to cool...the cut and colors are very stylish in almost any setting. I'll be wearing the Shaq for many years to come...on an everyday basis.

Bike, run, ski, hike, hang out...
The Ibex Wool Shak: It does it all. I love mine (and I have 3) and have worn them from riding a plane to cycling in the Tetons.

I have yet to rip one no matter what I do. Probably the single best piece of clothing I've got. I've not tried their new Shak Sport but that's my next purchase - maybe I'll wait until their sale but probably not!! Get one...(or two) if you can.

Wool rocks!

The one I grab for layer #2 each time.
I LOVE the Shak, I use it everytime I go skiing and I am sad when it is in the wash. Owning 2 would be good--then one would always be available. Great layer for summer hikes, boating, riding etc.

Best merino top ever made
Love the men's Shak Jersey! I'm female, 5'3", 115 lb, long torso, wide shoulders. I depend on wool clothes in winter because I get cold easily. The Shak fabric is my favorite merino -- the weave is warm, dense, smooth, durable, washes well and pills way less than other merino, and has a tiny bit of stretch to it. The reason I wear the men's Shak is because Ibex's women's tops are cut extremely sho

Always on, october-march
After getting one as a gift, I've gone on to collect four, worn day-in-day-out whenever it's cool or cold, often with ibex tee or woolies underneath, sometimes with a canvas shirt on top for a crisp look; ibex jacket if it's truly frigid out. What amazes me is how I can be comfortable both indoors and out with the shak. If an indoor space is *overheated* then I take it off, but otherwise it stays
