Versatile Comfort

We can’t all be laid back. There has to be a few intense folks, some let’s-get-this-done kinds of people as well. Fortunately, there’s a t-shirt that pulls its weight functionally, while offering up an impressively soft feel and low key look. The OD Heather T feels softer than you think wool might ever feel, which is good since the all natural fiber works harder than any other fabric at managing moisture and regulating temperature.

How Do I Determine My Size?

We recommend a general body measurement guide to determine your size in Ibex clothing. This sizing chart is not garment specific, but in fact a body measurement chart. Here are some helpful hints when measuring:

Bust/Chest: relax arms at sides, keeping the tape parallel to the floor, measure the fullest part of your bust/chest
Waist: keeping the measuring tape comfortably loose, measure around your natural waistline
Hips: standing with heels together, keep the tape straight and parallel to the floor, measure around the fullest part of hips
Sleeve Length: a 3-point measurement, standing with arms relaxed and slightly bent at sides, measure from the base of the neck to the shoulder and then from the shoulder to the wrist bone, add together measurements
Form-fit: garment designed to fit snug to the body throughout
Semi-fit: garment will be contoured to the body
Regular-fit: garment will not be slim, but also not oversized
Relaxed-fit: garment drapes loosely on body

Still need help determining your size? Call 800.773.9647 or email us at info@ibex.com for specific garment measurements.

Great reviews. I like other similar Ibex shirts and wanted a crew collar shirt for workouts. I have the Axis V-neck and love it.

My husband loves these tops, particularly for a casual t-shirt look or for a wicking shirt while exercising. He is a big guy....6'6", 240 lbs. and fortunately, the XXL works for him!

Chandra A on Feb 24, 2016
Birthday gift for my husband. He loves wool and often uses a workout T under his jacket during spring ski season. Thought this would be nice, and smell better, than his synthetic Ts.

will this shrink in the wash?
A shopper on Jul 28, 2015
BEST ANSWER: No shrinkage with this T in the washer----warm water and regular wash action. I only wash the shirt with like articles to protect the fabric. For drying, I dry in the dryer on cold air cycle.
How do these run size wise. Do they tend to be run small or large?
Dan S on May 23, 2015
BEST ANSWER: Hello the fit on the M's OD Heather T is a Regular fit. It is our more generous fit and it fits true to size. Thank you
I'm 193 cm (6'4") tall with an athletic build and torn between the medium and the large. According to the size chart, when I measure my chest and waist, I'm a large, but the main reason I'm having doubts about getting a large is that they seem rather long. I don't want my t-shirt hanging on my knees. Also, I'm from Europe and I have the impression American sizes are a bit bigger. Your thoughts?
A shopper on Jul 1, 2015
BEST ANSWER: Hi, I'm about 186 cm and 86 kg. I like the medium T shirts--- they are comfortably close-fitting for wearing under another layer. For Ibex shirts with a collar I chose the large. I don't think you need to worry at all that they're too long. Best of luck!
was puzzled by the review that said this shirt needs to be dry cleaned. Really? Also, what is the basic difference between this shirt and the U60, other than price? Finally, I'm 6'4'', 190 pounds. What size is recommended? Thanks
A shopper on Jul 9, 2015
BEST ANSWER: I've had no problems washing OD Heather tees on a cold delicate cycle and air drying them. Shake them well before hanging them to dry to minimize wrinkles. I prefer the OD Heather's weathered and more textured look over the U60. At 6"3", 190 lbs a large fits well. Length is fine, but not overly generous. This is one of my favorite shirts and a summer staple here in northern Minnesota.
What's the difference between this and the Seventeen.5 T?

M's OD Heather T

BEST ANSWER: Hello, thank you for your question. The main difference is the fabric. The OD Heater T is 100% Merino Wool, the fiber is 18.5 micron, and knit to 150 g/m2. This shirt has also been dyed twice to give it the heathered look.

The Seventeen.5T is 100% Merino, knit with 17.5 micron, and is knit to 165 g/m2. The main difference is that the Seventeen.5 is softer (17.5 micron), and the fabric is knit a little bit heavier (165 g/m2). Thanks again!
What's the difference between this & the od sol tee?
William on Jun 22, 2015
BEST ANSWER: Hello there isn't much of a difference between the OD Heather T and the OD Sol T. The only difference is the seam on the sleeves. Same fit and everything.

Buy One...Budget for More
This ain't your dads generation wool. Great stuff, as always. Bought two for starters. Would like to see another inch in the sleeves. A favorite, sustainable, performance fabric and product.

I have one for every day.
It started with one....i can't go back. Look good. Feel good. Smell good. Did I mention that the logo has sweet horns?

Just right fit
First, wool is everything it's cracked up to be. Second, the fit of this shirt is great if, like me, you dislike the trend of all clothes being tight fitting. This shirt has a true "regular" fit.

Fit, Durability & Comfort
I own the competitors, but when I want style, fit, comfort and durability I choose ibex. I wear them in layers and alone. All 4 seasons. So versatile, I wear them daily, and wouldn't use cotton again. Want more!

Best active shirt -- ever
I love this shirt, so much so, that I bought 4 of them. I just got back from 10 days hiking in Israel and I rotated the 4 shirts throughout the hike. The shirts would get very sweaty on the back where my pack rested (is there any way to avoid this), but after each hike, I would hold the wet shirt out the window of our moving car and it would dry in less than a minute. Zero stink and the shirt w

Best shirt ever
These are the best outdoor shirts I have ever owned. I have spent 30 years backpacking, skiing and mountaineering in the Rockies and North Cascades and have never owned a better shirt.

Wool is great for summertime heat
I live in the south where summer temps are high. Wool t- shirts keep me cool when I am outside in the summer heat and warm when I move inside to air conditioned spaces. The shirts hold up well to machine washing. I always air dry them. The fabric is soft yet durable.

Fantastic Color!
Great color. Really unique.

Travel time
In planning a 5 week trip to Europe which includied a week on the El Camino, I focused on light weight and easy to clean gear. Ibex and the Heather T worked perfect. The beauty of merino wool is breathability and the added benefit of being able to wear something more than once and not worry about the smell. Plus they dry overnight after washing. I'm 6'4"" , 185 pounds and the large fit "perfect".

OD Heather.
It wicks, is breathable, and light; and can be worn several times without smelling badly; what's not to like. I wear it under a fleece to bike commute to work and then keep it on under my dress shirt at work. Really so veratile. Blue color is great. For me compares to the U sixty I bought; also a great shirt. Hard to go back to synthetic or cotton now.
