Second Shak
I'm a recent Ibex convert and I bought the Shak Jersey after being very pleased with a Shak Hoodie. Like any Ibex garment, the design and quality are top-shelf and I really love the long athletic fit. I use the Shak Jersey mostly for casual wear or for layering to-and-from the gym. I ordered mine in the Burnt Sienna and it looks fantastic. Worth every cent!

Really Warm!
The Shak jersey is incredibly warm and not itchy. I have never had a problem with wool anyway but this feels plenty soft and is a really great warm and thick shirt.

Ibex's Shak line rocks
Sometimes it is best to hold off on the easy stuff and save for the best...that is the way I feel about the Ibex Shak line. I've got 2 of the hoodies and want more! My friends always want to borrow My Shaks when they show up without the right gear. I thought I would try this jersey to round out my wardrobe for many of the seasons in Northern CA. Here its all about layers and these impeccably cut and crafted pieces are all I want...add a underlayer when you are cold...put a outer layer over that if it gets colder..... or wear it naked when its just right In all fairness I am a Shak hoodie lover and so I am gonna go for another of those and save this jersey for dress up. The ocean winds where I wander demand ear protection and that little pouch up front carries my supplies. Live Simple Integrity...get Ibex!

A classic from Ibex
This is the sixth Ibex Shak item that I purchased. I own 3 Shak jerseys, 2 Shak full-zips and a Shak vest. The putty color is a bit darker than what shows up on the computer, and it seemed to pill more than my other Shaks in the wash, but this may be due to some fabric sourcing for this particular garment. I've been very pleased with the performance of all my Shak gear. If this pills any more, I'll contact Ibex. Their customer service is top notch.

Form Fit, Thin Layer Underneath
Got my Shak Jersey on sale in May so I won't routinely wear it till it gets cool again. Most already know the advantages of wool: it's warm, breathes, and controls odor well. This review is about sizing information. I bought the small. I'm 5'8", 150lbs and about a 37-38 chest size with shirt arm length around 30". The Shak Jersey definitely is a form fit. Only one or possibly two thin layers will fit underneath. By thin layer I mean capilene 1 or the equivalent. If you are bulky or have lots of upper body muscles, you may want to consider going up one size. The arms are about 1.5-2" inches too long for me. This is not really an issue. You can either turn up the hemmed sleeves to make cuffs, like a sweater, or pull the sleeves up above the elbows. The form fit keeps the sleeves in place if you pull them up. The Shak Jersey has a somewhat tailored look to it; something you can wear around town with a pair of jeans or better and look nice, or out on the trail in aerobic conditions. Zip up or down to control temps. A good quality product.
