Size XL for me is perfect, casual and roomy without swimming in it. I am eagerly awaiting the sun to go hiking.

5'6" 160 lbs 36c bra 60 year old with most if my weight in my midriff.
What I love: Nice and long (to mid hip), comfy neckline with hood on or off, great thumb hooks, nice color with material being thin but not sheer.
What was disappointing: Chose size large so this hoodie would be a bit loose since my Wuru medium tee fits my form perfectly.. Sadly, this size large shirt fits so tight that it stretches across my chest in ripples instead of lying flat and sucks to my torso like spandex. I rechecked the size that was sent thinking it must have been a small by mistake, but it's a large. I would only ever wear this as a hidden base layer.
Fits my 5'7" 125 lbs A cup daughter-in-law well.

At first I thought this is way too expensive for a base layer but, you get what you pay for! It is very soft, comfortable and super WARM! Really appreciate the oversized hood, longer torso, sleeves and thumb loops. Love it. Worth every penny and so glad it is made in AMERICA! I really wish they had darker and more colors available that would hide the dirt. It would be nice to have full-length pants too.

Love the color (dusty blue), the 100% merino, and the neck design for the hood part. I also like the thumb loops. I’m pear shaped but went with small because of the chest size on the size chart, but I probably could have sized up because it fits slimmer in the torso and sleeves than other similar hoodies I have from Icebreaker and SmartWool. The sleeve length might be a little long for me (reaches my knuckles with my arms down) but suits me fine. The torso length could be a few inches shorter (I am 5’ and it almost covers my whole butt), but it bunches up around the low waist/high hips because of how slim-fitting it is and because I’m pear-shaped. Not sure yet if I will get this hemmed. The fabric feels soft enough, not as smooth as my Icebreaker hoodie, but the Icebreaker got a few holes within a few months of light use; hoping this will last longer.

I love that I only packed this sun hoodie for a full wknd and it was comfortable in the sun midday, on the cool mornings and evenings!
