    Highly Recommend

    I already owned this shirt in another color and came back for more. The fit is excellent, the fabric feels premium, and it performs exactly how I hoped while traveling. I recently wore it on a trip and it was perfect. Comfortable on the plane, polished enough to go straight to dinner without needing to change, and it still looked fresh afterward. Great versatility and quality. Highly recommend.

    This shirt is great!

    The long sleeve merino crew from Unbound Merino is one of those rare pieces that quietly earns a permanent place in your rotation—it’s incredibly soft without feeling delicate, breathable across a wide range of temperatures, and manages to look sharp whether worn on its own or layered. The fit strikes a nice balance between tailored and comfortable, and the natural odor resistance of the merino wool makes it ideal for travel or long days when you don’t want to think about outfit changes. It’s the kind of garment that just works every time you reach for it, combining understated style with genuinely practical performance.

    Why didn't I try these sooner?

    These merino wool shirts are spectacular! They keep me from getting a chill indoors in the winter so I don't have to crank up the thermostat too high. And in the summer, these and the short sleeved versions don't let you overheat, even in 90 degree Fahrenheit weather! Extreme comfort and can be worn for days before laundering. The antimicrobial properties really do work.

    Amazing Material

    These Long Sleeve Merino Crews are a staple in my wardrobe. I have >7 of them at this point. I share 5/5 since the material, versatility, quality is amazing! My only recommendation is to size up in the Navy Striped version as I had to exchange for a larger size due to it fitting more snug than the rest of the options.
