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.

If I'm going to be on the trail for days on end without a shower, I want something light, comfortable, and most importantly, something that will not smell. This is the ticket!

what tee shirt fits most loose ?
A shopper on Aug 20, 2015
BEST ANSWER: Hello we have what is a Regular fit which is our loose fit. Most of our T-shirts are a Regular fit. This one is a Semi-Fit. Thanks.
How's W2 basic different from W2 sport?
Rob W on Jul 13, 2015
BEST ANSWER: Hello the only difference is the W2 Sport has black on the sleeve where the W2 Basic is all one color. Thanks

nice light fabric, but seems to run small.
Ordered a large (200 lbs 6"2) and after washing a bit tight…but for some folks they might like the form fit. Fabric is a nice light feel, and gives with your movements.

best shirt so far
loyal Ibex wearer for 15 years. This shirt my favorite short sleeve yet. Smooth fit, looks cool, merino qualities. What else can I say?
May 15, 2014
Barely there wool
Really like this shirt. Wish I had bought each color. Great to travel with as it does not carry smell and can be worn multiple days w/o washing. I have mountain biked in it as well as visited factories in hot and humid Asia. Could do without the grey color hits in the armpit area.

New favorite running shirt!
Great shirt. Fabric is really light. Doesn't stink after a long run. The blue color matches the picture pretty good.

Great for exercise
I have a few of these that I use for running and yoga. My previous shirts started to develop an unwashable stink that would not come out regardless of how I washed them. So far these shirts are great. I've worn them in 80F + sunny temperatures and they are no hotter than your standard synthetic sports shirt. Time will tell if they repel the inevitable stink, but based on other wool products I thin
