The Long Version:

“Hiking gear starts with your underwear”.

It’s not the slogan of our new hiking underwear brand. It’s just a fact.

When setting up for a hike or backpacking trip, the first item to attach itself to you will be your underwear. It goes on before any of your other worn clothing (ideally anyway), and before any of the carried gear in your pack.

Because your underwear is a next-to-skin baselayer, it needs to function well. It should be breathable, moisture-wicking, fast-drying, and — ideally — it should not feel damp or cold when wet.

And, not all underwear are created equal.

Materials commonly used to make your city clothes — in particular, cotton — do not perform well during active use or in cold and wet environments. Cotton absorbs water, after which it is heavy, slow drying, and does not insulate. So during active use — when you are likely to be sweating — cotton is the last thing you want against your skin.

So if not cotton, what else?

There are various materials and styles used for hiking underwear, but suffice to say that the two most popular materials are merino wool and synthetics. If you are not familiar with the benefits of merino wool or synthetic fibers used in hiking underwear, then check out our buying advice at the bottom of the page.

Otherwise, let’s just jump straight into it.

Here is our list of the best men’s hiking underwear. These high performing undies will have you travelling comfortable all day long, so that you can focus on the more important task of getting up that mountain!

Smartwool Merino 150 T-Shirt

MATERIALS: 87% merino wool, 13% nylon

CUT: T-Shirt

PROS: Comfortable fit, Flat-lock seams, Lightweight, Quick drying

CONS: Expensive

BEST FOR: Those who want the best merino t-shirt around

MRRP: $$$

Without a doubt Smartwool make some of the best baselayers for hiking, backpacking, and travelling. Their material is comfortable against the skin, and the garments are well made and durable for merino.

Hence, the Smartwool Merino 150 Base Layer T-Shirt is our favourite shirt for three-season hiking, when we don’t require the extra protection of a collar or long sleeves.

Smartwool use flatlock seams throughout. This is especially important through the shoulders and under the armpits, where the rubbing of your backpack or the movement of your arms are most likely to generate chaffing.

You of course have the added benefits of merino wool — namely, that it is far more odour-resistant than synthetic, and that it doesn’t feel too bad when damp. The lightweight 150-weight material is also lightweight enough that it dries relatively fast. Much faster than cotton, and about as fast as a synthetic polyester or nylon (discussed more in our buying advice below).

While many people have reservations about the durability of merino products, we’ve found the Smartwool 150-weight merino range to be very durable. In general, we’ve found Smartwool’s merino baselayers to be far more durable than many other manufacturers’ merino baselayers. What's more is that Smartwool now use a nylon core with merino wound around it. This increases durability but retains the benefits of merino against the skin.


BUYING ADVICE FOR HIKING SHIRTS

MATERIALS

For the most part, there are two possible choices when it comes to materials for hiking shirts. The first is merino wool, a natural fiber. The second is synthetic fibers, primarily nylon or polyester.

Both merino and synthetic materials have pros and cons. If you are interested in reading about them in more detail, then check out our article Which Baselayer Is Best? — Merino Wool vs Synthetic.

In brief though, both have great moisture-wicking properties, are quick drying, and will keep you insulated when wet.

The upside of merino is that it is soft, naturally odour-resistant, and feels nicer against the skin when damp. The downside of merino is that it is expensive and less durable.

The upside of synthetics are that they are less expensive and more durable. But the downside is that they aren’t as soft as merino and — although they dry slightly faster than merino — they don’t feel particularly nice against the skin when wet.

Whether you opt for merino or synthetic will depend on: your budget, your demands for durability, and your personal preferences (some people just really love merino, others just really love synthetics… personally we are the former). In some cases, manufacturers will use a blend — for example, merino wool wrapped around a synthetic nylon core — like in the Smartwool Merino T-shirt reviewed above. This can lead to the best of worlds, since you get the benefits of merino against the skin, but the added durability of the synthetics.

ODOUR-RESISTANCE

Merino wool is naturally odour-resistant, so if you opt for a merino hiking shirt then that will be an added benefit.

Unfortunately synthetics don’t offer the same natural odour resistance. Some manufacturers treat synthetic fibers with an antimicrobial coating to increase odour-resistance, so that is something you may want to look out for. However antimicrobial treatments often don’t live up to their promises and they will fade after repeated washing anyway. So we don’t suggest you let antimicrobial treatments be a big factor in your decision.

DURABILITY

Ideally you want a hiking shirt that will stand the test of time. But durability is an area you may need to consider a trade-off. Synthetics are likely to be more durable than merino wool, so you need to simply decide which factors are most important to you.

WASHING CARE

When it comes to washing, merino wool requires slightly more care than synthetics. But the amount of care required is sometimes overrated. In most instances, you can throw your merino underwear in the wash with your other clothes, just try to be sensible and be sure to avoid excessive heat. Ideally, wash them using cold or warm water, and usually with a medium spin, rather than trying to thrash them to shreds using a fast spin cycle.

Due to it’s odour-resistant properties, merino doesn’t need to be washed as often as synthetic either, so try to only wash your merino garments when they actually need it. It will prolong their lifetime.

You can even throw good quality merino in the dryer, if you really need to. Just be sure to keep the temperature on low! A hot dryer cycle will leave you with a shirt five sizes too small. Although, it is always better to air-dry your garments if possible. Both synthetic and merino dry pretty fast, so if you have a day to spare — or even just a few hours in the sun —then aim to just dry them naturally. Although, avoid direct sunlight if it is very hot, and don’t hang garments if they are very wet (they might stretch!).

Having said all that, here is our disclaimer: “always follow the manufacturer’s care instructions shown on the label” (sort of…).
