Long-Sleeve Merino Wool Shirts

How to choose

Check sleeve reach with your arms forward, not only hanging at your sides. A sleeve that looks generous in a standing photograph can pull back when you drive, cycle or hold trekking poles. Ask for the manufacturer’s measurement method before comparing sleeve numbers from two different brands.

Cuffs can change the experience of the whole shirt. A narrow cuff stays close under a jacket; a wider opening may be easier to push up. Thumb loops, when present, are a specific feature to evaluate rather than a reason to assume extra sleeve length.

Separate a shirt for exposed daytime wear from a top intended to disappear beneath other layers. For the first, consider the hem and neckline as part of an outfit. For the second, check whether seams and cuffs create pressure beneath your outer clothing. If sun protection is a deciding factor, use the UPF-label guide rather than treating sleeve coverage as a measured rating.
