The Top Wool-Based Shirts For Hiking: Everything You Need To Know
Like any outdoor gear, woolen shirts can be a hit or a miss. As a result, it’s imperative that you know what to look for before you buy.
In this section, we’ll give you the low-down on everything you need to know about woolen hiking shirts to help you on your way.
What Is Merino Clothing?
If you’re in the market for a woolen shirt, you’ve probably heard folks talking about merino wool. But, what exactly is merino wool?
Basically, merino wool is a type of fabric that comes from a specific breed of sheep—merino sheep. Merino sheep are most commonly found in New Zealand and Australia, so most shirts with merino fabric are sourced from these two countries.
Compared to regular woolen fabrics, merino wool offers a number of benefits. While your standard woolen sweater is likely to be itchy, heavy, and bulky, shirts made with merino wool are anything but.
In particular, some of the many benefits of merino include:
- High breathability
- Excellent moisture-wicking properties
- Quick-drying abilities
- Machine washable
- Anti-microbial properties
Given all of the above, merino wool garments are a solid all-around choice for use in just about all outdoor environments.
How To Choose A Wool Shirt For Hiking
Now that you know about the benefits merino has to offer, let’s talk a bit about how to actually choose a woolen shirt for your adventures.
The first thing you’ll notice when shopping for merino wool t-shirts is that these shirts all have a “fiber diameter” listed in their specs. This diameter refers to the size of the individual fibers used in the fabric.
Fiber diameters are expressed in something called microns, which is a millionth of a meter. You’ll see anything from about 15 microns up to 21 microns in most merino wool t-shirts.
Basically, the lower the micron, the softer the merino. The best merino wool shirts in terms of comfort and performance normally have a fiber diameter of around 16 to 19 microns. However, the smaller the fiber diameter, the more expensive and less durable the shirt is likely to be.
In addition to fiber diameter, another spec you’ll see on your standard merino wool t-shirt is something called fabric weight.
Merino wool fabric weights are expressed in grams per square meter (gsm). In a merino wool t-shirt, you’ll normally see weights between about 100 gsm and 400 gsm.
Essentially, the lower the fabric weight, the thinner the fabric. While there’s no single fabric weight that’s best for all environments, something in the 100 to 200 gsm range is ideal for warmer conditions. Meanwhile, 200 gsm and up is usually better for colder temperatures.
Garment Fabric Composition
If you’re reading this article, you’re probably looking to wear a regular or merino wool t-shirt on your adventures. However, it’s worth mentioning that relatively few merino wool t-shirts on the market are actually made from 100% merino.
In fact, most are a blend of merino and nylon. Merino/nylon blends are very popular in the industry because nylon provides the durability that thin merino fibers naturally lack.
However, adding nylon to a merino wool shirt does decrease some of merino’s natural softness and moisture-wicking abilities. It also makes it slightly less breathable and less quick to dry.
The take-home? Opt for a shirt with lower nylon content if breathability’s your main priority; shoot for a nylon-rich option if you’re more concerned about durability.
Finally, it’s worth mentioning that both regular and merino wool shirts for hiking don’t come cheap.
Most woolen tops sell for 3 or 4 times the price of your standard short-sleeve crew tee, so they’re not the most economical option out there. Models that are made from a blend of nylon and merino tend to be more affordable, but they’re still pricier than your standard cotton short-sleeve tee.
So, if you’re working with a tight budget, a merino wool t-shirt that has nylon blended in is a great option.
