Smartwool Men’s Merino 150 Boxer Brief
If you don’t mind paying a bit more for reliable, quality, and versatile underwear, look no further.
Merino wool, combined with a nylon core and a wide elastic waistband provides a comfortable and odor/smell resistant experience. This is probably the best material combination for hiking underwear.
The Merino part, soft and gentle on your skin, is naturally antibacterial. This will keep your private parts fresh, clean, and odor-free at all times.
The synthetic part has a moisture-wicking feature. It will help you stay dry and avoid the feeling of dampness in your groins.
Keeping everything in place for ultimate comfort, flatlock seam construction is designed to rule out chafing.
The only downside I’ve found to this item is its price. Sure, they are pricier than the other options. However, they won’t let you down on any occasion.
- Comfort – if you are feeling your underwear too much on your skin – it’s probably a bad pair. Always aim for flatlock seams and gentle materials. They will provide you comfort and eliminate chafing during your activities.
- Versatility – not only can you use them on longer hikes, but you can also use them during your day-to-day life
- Durability – Just like with versatility, you want a quality and durable pair of underwear since you will pay for it more than expected.
- Price is the only downside to this pair. However, with all the great traits they kinda make up for the price.
Best for: People who want a versatile and durable pair of underwear and don’t mind paying extra for high-quality design and comfort.
Arc’teryx Phase SL Boxer Men’s
Don’t you just hate when the inner stitches of your underwear leave marks on your body?
Well, Arc’teryx Phase SL Boxer has this problem solved.
It’s called “flatlock construction”. It really makes that necessary contact between underwear and your private parts more comfortable.
Besides, these boxers have a non-chafing label. This means no more scratching, and no more ruined underwear while trying to remove the label.
On the other hand, they don’t have a fly so this is something you need to be aware of when choosing your briefs.
- Comfortable – with anatomical shaping these boxers will move with your body. The flatlock seams and the non-chafing label will be gentle on your skin.
- Light – made of polyester, they will provide silk weight performance during all of your activities.
- Dries fast, moisture-wicking – you can freshen them up even when you are low on time and out in the wild.
- Versatile – comfortable and light enough for all types of activities.
- Price – considering the synthetic (versus natural Merino Wool) polyester materials these boxers are kinda pricey.
- Odors – as lightweight as polyester might be, it is prone to developing odors quickly
Best for: Active campers who enjoy wearing comfortable and light underwear during easier hikes.
Minus33 Merino Wool 702 Acadian Men’s Lightweight Boxer Brief
If you are looking for something more versatile and also cheaper, Minus33 Merino Wool 702 Arcadian is an excellent choice.

Having discreet yet strong flatlock seams, these boxers keep your skin from chafing and your private body parts comfortable and cozy.
The downside is that Merino Wool is prone to tearing, so even though they are machine washable, you might want to avoid doing this. At the very least I would recommend washing them in a laundry bag.

How To Choose The Best Hiking Underwear
Hiking underwear is a really important (though kinda underrated) part of hiking equipment.
It is the layer closest to our skin, and it can give us some real troubles if we don’t choose wisely.
There are several things you need to watch out for, such as:
- Cut (and the design)
- Odor resistance and moisture-wicking
Cut And Design
When choosing your hiking underwear probably the first thing you need to decide on is the type of it. Most men’s hiking underwear are boxers or boxer briefs.
Boxers are similar to shorts, giving you more freedom and space, while boxer briefs are tighter especially around the thighs.
Which one you are gonna choose is completely up to your personal preferences and the specific model of underwear.
However, keep this in mind: you don’t want your underwear to be too loose, in order to avoid chafing and rubbing. BUT, for the same reason, you don’t want them too tight.
As for the design, there are also features that will help you avoid the chafing and rubbing problem. Look for underwear with flatlock seams.
Like I mentioned before, this means that the two edges of underwear material are sawn directly together in a way to eliminate any possibility of discomfort and skin irritation.
Furthermore, you might also want to look for underwear with a gentler label, also in order to minimize the rubbing and chafing accidents.
A functional fly is another feature that can come in handy when you are out in the wild with a bunch of layers and stuff you carry.
Most of the hiking underwear has two material options.
- Merino wool
- Synthetic materials like polyester
Both of these options have their perks. They are both moisture-wicking and quick-drying materials which are great for your longer and multi-day hikes.
Synthetics are cheaper and more durable, whereas Merino Wool is softer, more enjoyable on your skin, and naturally odor-resistant.
On the other hand, Merino Wool is a bit pricier and less durable than synthetic materials.
Polyester and nylon, even though cheaper and more resilient, don’t feel as nice on your skin as Merino, especially when damp.
Your choices will depend on your personal preferences and funds, so keep in mind that there is also a third option, which is the combination of the two like with Smartwool Men’s Merino 150.
Odor-resistance And Moisture-wicking
Odor-resistance and moisture-wicking properties are probably among the most important features your hiking underwear should have. They help you stay fresh, cool, and odor-free on any occasion.
However, this isn’t a regular feature with all the hiking underwear.
For instance, Merino wool itself is naturally odor-resistant and antibacterial, so any brand and model you choose made of merino wool will have you covered.
On the other hand, synthetics are a bit different. Some models might be prone to developing odors more quickly.
So if you are buying underwear for multi-day hikes where you might need to wear them without washing for some time, merino wool is the smarter choice.
Whether you use them in your day to day urban activities or carry them with you on your hikes and camping trips, this is an important feature.
If you are into versatile usage, you want underwear both hand and machine washable. Also, you might want to look for that quick dry feature, for when you are away on your hikes.
So what did I learn after reviewing so many men’s hiking underwear?
It’s simple. The #1 choice (easily) is Smartwool Men’s Merino 150 Boxer Brief.
The combination of the two best hiking underwear materials makes them the most durable, versatile, and comfortable option.
Yes, they do cost a bit more. However, with this pair, you can forget all about bad odors and the feeling of dampness in your groin.
Gear up and go on your hike peacefully, knowing you gave your skin the best there is.
