The Fuse Merino is a super-comfortable base layer with a hood. The soft merino wool mix is super-stretchy, fast-drying and moisture-wicking, making it perfect for chilly days in the mountains.
Recently purchased the merino wool set and this was the second pair of base layers from RR. Both sets are of exceptional quality and both performed very well on a recent camping/mountain hike in temperates well below freezing. Best advice to anyone buying RR products is to just buy them, you certainly get what you pay for and both sets are of a very high quality. You won't be disappointed.

I am a muscular guy with a slim waist, the fit was perfect (i bought S-M size), so consider that the fit is on the larger side. It's warm but I have yet to test it in the real world. I think it could be a little thicker, but it's a base layer so it doesn't matter that much. The material is very nice and the color also (a bit darker in person).
Fits well, extremely soft on the skin, it doesn’t irritate like some Merino Wool garments. Haven’t been able to test its thermal properties as yet but first impressions are impressive.
Perfect base layer worn under a drysuit when whitewater kayaking. Really impressed with the performance when it came to keeping warmth in but allowing moisture out. The hood is a nice touch as it’s not too bulky and can be folded away when necessary. A little expensive; maybe, but you get what you pay for.
