The Ibex Promise
We’re committed to uncompromising craftsmanship and to your satisfaction. If you are unsatisfied for any reason, return your purchase within 60 days with proof of purchase to receive an exchange, repair, or refund. It's our promise.

We brought some new color to the classic Woolies 150 Crew for the new season, but left the amazing performance unbothered. Our original Woolies long sleeve layer, the Woolies 150 Crew has done duty on high alpine expeditions, World Cup ski races, fat biking marathons and adventures less extreme (but no less deserving of natural fiber warmth.)

The rib construction provides space for air permeability contributing to superior performance and excellent stretch and recovery. Naturally odor resistant, or "no stink" is a huge bonus.

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.

Good reviews. My outdoorsy son is always looking for items like this.
Guest S on Dec 21, 2015
Good as a base layer for outdoor activities but also works well for a first layer for indoor days.
Sheila S on Dec 21, 2015
This is the perfect winter undershirt.
Paul H on Dec 15, 2015
Nice, bodysnug base layer
icqcq on Dec 10, 2015
About 60X more comfortable than wearing synthetic layers. I haven't had a chance to wear it much during the drought/heat in SoCal, so I can't comment on performance. Fits great.
Jerry F on Nov 25, 2015
It was on offer, but the colour did not suit me so I gave it away
Capt. Mirek on Nov 23, 2015
Baselayer supreme. There is always a reason to wear this shirt, even in summer.

my husband loves marino wool base layers
beverly n on Sep 24, 2015
Can't beat this base layer.
Guest S on Sep 20, 2015
Same reason I bought the short sleeve.I bought this in black as a gift for my husband who is always cold. He likes to wear a T under his button down shirts. I am trying to sell him on the fact that wool is much warmer than cotton. I'll let you know if I have succeeded once winter sets in!
Skowronsky K on Sep 18, 2015
Perfect base layer. No stink and lasts for years. Wool is for life!
Cyclewithcoffee on Sep 18, 2015
good looking, athletic cut and quality product.
Sean M on Sep 11, 2015
After reading reviews and researching merino wool long sleeve shirts for my RTW trip, the Woolies 150 proved to be the best value.
Sean A on Sep 2, 2015
Winter under garment for work, play, and everything under the ski lift. Second skin is an understatement.
Kristopher W on Aug 28, 2015
Needed lightweight (150) baselayer and this was a better cut (raglan sleeves way better comfort esp. when carrying loads), fit and colour choice compared with smartwool and icebreaker.
Damion S on Aug 25, 2015
Going on winter trip to cold climate
Alexander M on Aug 25, 2015
only wear wool for base layer
william d on Aug 21, 2015
Woolies are my absolute favorite baselayer. I wear one pretty much everyday in the winter months, which in Minnesota is from late November through the end of April. I love that they don't get stinky and they really do wear like iron. I'm just now having to replace ones that I bought 5+ years ago and have finally worn out.
Kathleen L on Aug 19, 2015
perfect Christmas gift for outdoorsy son in law
Joan P on Aug 18, 2015
My son convinced me that Ibex was better than Smartwool. He was right.
John W on Aug 18, 2015
i like merino wool
albert r on Aug 18, 2015
I needed a good base layer for skiing. I own Woolies bottoms and love them so it was natural to get the Woolies Crew. Ibex makes great stuff.
Kevin G on Aug 17, 2015
Looking for some new cooler weather gear, and love wool!
Jason T on Aug 16, 2015

Timothy M on Aug 16, 2015
Need a wool baselayer, and this does half the trick...I waited too long and missed out on the bottoms.

What is the sleeve length for the larger sizes?
A shopper on May 13, 2015
BEST ANSWER: Hello the sleeve length on the Large Woolies 150 Crew is 33" and that measures from the center back neck to the sleeve end. On the XL is is 34". I hope this helps you with your decision.

I was looking for a layer for running this winter. This is like a thin wool TShirt. It's a thin base later! Size yourself UP when you order it. I"m 5'6" 145lb and that makes me a small. But in this crew shirt, Im a Medium. Now you know.

comfortable when wet
running in cool temps, backpacking/mountaineering base layer

Best Winter Foundation Shirt
The Woolies 150 Crew shirt is the only foundation shirt I wear in the winter, except when it is really cold, then I wear a half-zip.
The woolies are not only warm but also comfortable and stylish when worn under a shirt-over. I not only recommend the Woolies 150 to friends but I also buy them as gifts at Christmas

Wore this crew for the very first time running the cold, rainy, windy 2015 Boston Marathon. It was a perfect fit with just the right amount of warmth and protection. Will be an all-time favorite.

This fits the bill like a champ. Thanks Ibex, you rock!!!

comfortable, fitted top
I own quite a few of this top. I wear them as a baselayer all winter, and then as a base with a t-shirt on top in spring. Depending on the color, they can work as a stand alone t-shirt too.

Can't think of one negative
All good.
I use it for:
in the office
lounging at home

Never smell, I can wear this 3-4 times (even running) and hang it and never have a problem with odor.

Love the fact that it is now made in N. America.

thin, warm, perfect
got this for my husband, who tends to like looser shirts. got a L (he usually wears M), and it's perfect. he also won't stop wearing it. not itchy, perfectly warm (he's a human furnace), and great under t-shirts. just ordered him another one so i can at least wash the first one!
January 2, 2014
Great item!
I generally wear this item with a vest. It's not bulky. The color and weight of this shirt are ideal. One of my favorite things to wear.
