Our Verdict

The WoolX Hannah balances performance and price as the highest value merino wool contender tested! Featuring 230-g of 100% Merino wool that is touchably soft, you'll want to wear this shirt every day. The fit works well for a diversity of body types because the material stretches and conforms to every curve of the body. The longer arms and torso provide great coverage locking in warmth. It also doesn't stretch out or shrink with use. When testing in Northern Ontario during the polar vortex, temperatures plummeted to the double negatives. We wore this as our base layer under just a jacket, and we found ourselves staying warm while taking a hike on a frozen-over lake. As a result, it's one of the warmest base layers tested that breathes as well.

Our Analysis and Test Results

The Hannah is the best valued Merino wool base layer tested. Versatile and fit for active or standing use, it provides a wide range of thermoregulation that will keep you comfortable throughout your next adventure. Build a snowman, go running, or take a hike in this super versatile layer.

Utilizing 230-g of Merino Wool, the Hannah is one of the warmest base layers in this review. In comparison to other synthetics, it thermoregulates better through a wide range of temperatures, keeping us comfortable in temperatures reaching up 70-degrees F and dipping down into the double negative digits.

Like all Merino wool contenders, its breathability is quite nice! We took this shirt running in conditions that varied from warm to cold. In all conditions, it wicked away moisture effectively keeping us comfortable and dry…even when stopped. Truly take this top anywhere…it won't need to air out even in your sweatiest endeavors.

Comfort & Fit

This is one of the most comfortable and well-fitted shirts in this review! Constructed of soft 100% Merino wool fibers, our testers love its super cozy fabric fibers that feel comfortable next to the skin. The fabric isn't itchy and it stretches to provide a great fit for all body types. The size is true to fit and the torso and arm length are ample, allowing you to reach overhead without the fabric slipping to expose any skin. The fabrics are also thick, so you can wear them all day comfortably without a care in the world. Grab a cup of tea and curl up with your favorite book on a cold, rainy afternoon.

Layering Ability

With a grabbier face fabric that stretches, but doesn't hug the skin like other competitors, we found this shirt a little hard to layer under tight mid-layers. Being a little thicker, when paired with another material that is fleecy or soft, it sometimes bunches up and even rides up. However, under a slippery mid-layer, it performs just fine. The additional torso and arm length are helpful to hold onto when pulling on another layer. The stretchiness of the fabric enables you to wear a lightweight tee or tank underneath as well.

Layering the Hannah is a little harder than other synthetic competitors because of its stickier face fabrics. That said, we enjoy the long arms that allow us to pull them through the mid layer.

It's not a surprise that this Merino wool contender is not the most durable in this review. The fabric, like other wool contenders, snags and can rip if you're not careful. Throughout our testing period, we also noted a couple of minor stitching fly-aways and pilling after washing. But, this is us being supercritical as outdoor gear testers.

After our three month testing period, no serious wear and tear was noted even after wearing a backpack (and no other layers) while skiing and hiking through the backcountry. Overall, there are no serious durability issues and it performs as any Merino wool shirt should.

As a high-performing product with a fair price tag, this Merino wool option provides a lot of value.


This high-value 100% Merino wool midweight base layer is highly versatile and perfect for any outdoor endeavor. Layer it or wear it on its own for all-day comfort. We especially love its low comparative price tag!
