One of the best - if not the best - winter weight base layer tops we've ever used. Excellent, super soft and comfortable winter-weight baselayer top that's nicely designed and made. What impressed us most is that despite being a relatively thick fabric, it still manages to deal effortlessly with moisture, dries decently fast and resists odour as well as anything we've used. Simply an ideal cold weather mountaineering or general outdoor base layer that shrugs off multi-day use. Yes, it is expensive, but it works very well indeed.
The Jottnar Uller Yak Wool base layer is a very impressive garment and has delivered on all counts. It has kept me warm, wicked away moisture superbly, stayed smell free, been extremely comfortable (I normally find wool itchy and this hasn't felt like that at all). It is also a stylish base layer that feels like it will last well. So, as with all the previous Jottnar products I’ve tested, this ticks all the boxes and would score an A* in any exam.
