Smartwool Microweight short sleeve runs almost a size smaller and is cut slimmer than the icebreaker tech T. Both are slimmer than Ibex Ts. Smartwool has the tightest sleeves followed by icebreaker followed by Ibex.
FYI, icebreaker tech T has become wider and longer in the last couple years…I have heard that this has affected the men's line too.
Size inflation is nothing new, of course.
I think you will find the Icebreaker Tech T much roomier than your Smartwool Microweight T in the same size…you may even want to size down.
I buy icebreaker for my dad from time to time…he thinks it's getting TOO big…he's a small so he's been sized out.
Watch out for "measurements provided"!
And forget about Patagonia. They have been trying to get merino right for years. Patagonia merino is a crapshoot and the sizing is all over the place…one color is sometimes a different size than another color. And the quality is not up to the contenders mentioned above.
For cross over casual, I think Ibex is the smartest looking stuff for both sexes. The fit is less technical though.
Just saw the post about the Ibex OD heather. I ordered one too in the ladies…yeah, that is probably the most relaxed of all. But if you are slim waisted and using it for backpacking…there may be a little TOO much material around the middle.
Ibex wins hands down when it comes to style points!
Yes, Ibex woolies are skin tight…they are a special exception…and they are marketed as underwear!
Yeah, I'm sure you were looking for a women's point of view on such matters. LOL
There was lots of Ibex about 30% on Amazon.com sold directly by Amazon a few days ago. Amazing what Amazon is getting into these days.
