Good‑quality T‑shirt, but the fabric weight or thickness makes it feel too warm for hot weather; otherweise, I like color and style.

Delivers Great!
It fits great and feels very comfortable and soft. Dries very fast and keeps me dry.

Bad Shirt
The models in the picture have the same build and same hight as me and when I bought the shirt it fit like an XXL and I ordered a medium. Looked nothing like the photo.

Super Comfy
Love the soft feel, breathes great, excellent travel shirt, wore it for two days in a row due to a packing mishap and didn't even smell at the end of day two. Fit is nice and not too clingy, but longer than my usual tees. Would love some more colours now

Poor Quality
The fabric is thin, wrinkles and is pilling after one hand wash and air dry. I’ve worn Arc’teryx merino wool shirts for years and am disappointed in the diminished quality.

Sizing Way Off
What has happened to the fit on all Arcteryx clothing? I have been a devoted Arc customer because the Large sizes fit me perfectly. Lately all the larges are huge on me and the mediums tiny. I am 6'2'' 200 pounds average build. I am seeing this trend across the industry and im not sure why. I have several Ionia wool shirts - long sleeve and short sleeve. My most recent one purchased 6 months ago but this newest one is so off on sizing I feel like I need to write a review. Quality seems fine and the materials are ok. This version I found is a bit softer than previous years'.
Attached is an image of my recent Ionia purchase from 6 months ago on the right - size large. the black one is the newest one of the left also size large. The new one is boxier and way longer.

Stupidly Superb Tee
I’m 5’10” 160lbs and the small fits perfectly snug. I climb, run, and lift weights with these shirts (currently own 3). The fit is flattering and intelligently articulated, the merino wool is top-notch, and the aesthetic is refined and clean. Bing-bang, giddy-gang.

Easy Choice For Comfort
L fits beautifully with nice length on both the body and sleeves. The light grey is a bit sheer but expected for merino; not an issue with darker colors. Super comfortable as a base.

Merino Base Layer
Light, comfortable and warm, everything I look for in a base layer

Extendo
The shirt is a little too long (dec/2024). It is not something I will choose to wear as a daily tee shirt but more as a baselayer covered by a sweater or jacket. I don't want to look kooky with the long fitting extendo tee look. The material is thin as well.
