this has been a great multi-purpose long sleeve for me. it's great for winter running. but i think i've worn it most for ski mountaineering. solid piece. had i not just tested the "natural antimicrobial properties" of wool i would have thought that was BS. however, this weekend i ski toured saturday and soaked the shirt to the bone. then woke up on sunday and put it back on for running.. and really, it didn't stink AT ALL. kind of amazing.the only knock on this shirt is that it could be more durable... but that is what you get with a lightweight shirt i suppose.

I have this and the matching pants. It is always my go-to baselayer. It handles heat and moisture better than any of my synthetics, but it's most redeeming factor is found in merino wool's ability to handle odor in ways synthetics normally can't. I use this baselayer for ice climbing, skiing and winter backpacking. It's comfortable (not scratchy at all) and non-restrictive, even though it's not a loose fit. I can't say enough times how impressed I am with this product.

I was really surprised when I got this piece. I love merino and have pieces from most of the other manufacturers. I've heard great things about Ibex but was really disappointed. The merino is soft but the knit of the garmet makes it feel really rough...totally defeating the purpose (and price!) of merino. Super skin-tight fit. It will keep you warm and handle perspiration well, but for my money I'm going for something softer.

Ibex brand is always a solid buy. Merino wool materials always perform to my liking and are super soft.
A little pricey for a layer, but at least it is made in the USA and the make is high quality. Cant find much made in the USA anymore....

I wear this cold weather biking under a softshell and stay plenty warm.

I haven't been able to put this to the test in the field yet due to a deployment, but i'd say a deployment is just as demanding on gear as field use. This is the perfect first layer. Never excessively warm. VERY comfortable. Thought the high collar with zipper would bother my neck but didn't even NOTICE. Don't expect to wear this alone as your warmth layer in freezing temps. I wear it day and night.
