Affordable price, delicious clothes

The first choice for mountain climbing

icon-circle-checkmark verified purchase



Excellent boxer shorts used on various trekking trips in both summer and autumn. Never been hot in summer or cold around 5 degrees so for me they are excellent considering the price.


The recommended size is quite small and is very tight. It is also so thin that it is a little transparent. As for its behavior against cold, odor and sweat, perfect.

Comfortable and efficient

Worn on the trip (16h+) they behaved very well. The material is pleasant to the touch, it regulates the temperature well (I left at 22 degrees and arrived at -3). It remains to be seen how they will behave in time.

Very comfortable boxers, easy to wash, even with any hand soap, they are perfect during treks. They don't sweat much, they don't retain bad odors, really excellent.

Just missing a little...

Just lacks a little originality

icon-circle-checkmark verified purchase

Tested during three days of trekking in the summer and since then used for every outdoor activity. No feeling of humidity on the skin despite sweating, and despite going for days without a shower I had no problems with bad odor (I repeat that I sweated profusely). I was more than satisfied, I bought two more pairs.

Due to a damaged item, I returned the panties I ordered. I had no problems with the return

Merino boxers

Great boxers, I love wearing them.

an effective product but...

Yes it is effective, for odors and perspiration, when I put it on I have the impression of seeing almost nothing, unparalleled softness and no itching, ultra-fast drying. But what's the problem? First of all, I would like to point out that I wash it gently by hand and dry it flat. The problem comes from buying 1 piece of underwear for more than €20 that we take care of it but the seams fray more and more every day on both sides of it at the first wash. started and given the price we hope for a quality product it's a real shame I'm going to buy 1 more if this one does the same thing I'll know what to write and put as a note.

Very good

Good material and loose fit

Good but...

The elastic at the waist tends to roll on itself, which makes the boxers uncomfortable in the long run. Too bad for a product designed for trekking...

Additional Product Information


Main fabric: 86.0% Wool, 4.0% Elastane, 10.0% Polyamide

Sizing and fit

These boxers have a fitted cut for enhanced moisture transfer to the outside of the fabric.

How have we enhanced the durability of our boxers made with merino wool?

We have used a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibres and protect them from rubbing and breaking without affecting their properties.

Tip before use

To make the component feel softer, don't hesitate to wash your boxers before first use.

How to wash your merino wool boxers

We recommend that you machine wash your Trek 500 Merino boxers at 30°C on a normal cycle, preferably with liquid detergent. Dry flat and NEVER tumble dry unless you want it to shrink by one or two sizes!For more information:

Product testing

These boxers have been tested and validated in the field in real-life conditions. They were worn for 5 weeks in spring 2019 by several people who went trekking in the Canary Islands for 2 weeks, followed by 3 weeks on the GR10 route in the Pyrenees.
