I’ve had brilliant Merino baselayers before and I’ve had thin midlayers with the other features of Rab’s Merino 160 Hoody before (hood, long cuffs and deep chest zip)… But this is the first time I’ve seen the material and features combined and it makes a lot of sense!

During uphill slogs and on sweaty pitches the Merino+ wicks moisture away, fast. This helps keep you cool when you’re working hard, but then on long cold belay sessions, having a dryer layer against the skin means warmth and comfort. I'm not going to pretend I understand how the 37.5 Technology treatment works, but I can attest to it keeping me comfortable.

The cut is fairly long helping to keep it neatly down under the harness rather than riding up annoyingly while flailing with your arms above your head climbing. The arms are long too with extended cuffs and thumb loops keep the wrists toasty but also help keep fingers warm, they need all the help they can get sometimes.

On a sport climbing trip in January I wore this top almost every day for a month, mainly because I knew the merino wouldn’t smell after days and days of constant use! January in Spain means freezing mornings, and often warm sunny days. The medium weight was great under a couple of layers on the cold mornings. And then, in the sun on baking belays and longer routes the hood was ideal for keeping the burning sun off my neck and arms, it sounds crazy but I actually love it for that. But I guess Rab had winter in mind when they added the hood? In the cold with the hood and zip up your face is nicely cocooned. It goes under a thin beanie with space to fit a helmet properly over the top, making a lovely warm combination.

Then there is the deep chest zip which is brilliant for keeping your temperature regulated on uphill slogs, running, mountain biking, walking, climbing... And yes, the zipper is big enough to handle with a pair of gloves on, attention to detail!

The combination of having this deep chest zip as well as the thumb loop cuffs and hood make the top incredibly adaptable, and the wicking nature of the fabric makes it an ideal base layer as long as it’s under something breathable. So it’s the perfect natural fabric with a great cut and just the right amount of ‘features’. Great, nice one guys.
