The best

Fantastic boxers, worth the price, and they outperform all premium brands that put the visibility of the logo in the foreground.

Good breathability and tight fit.

Good breathability and tight fit. The upper elastic could be less tight, although my priority was to prevent them from rolling up and tightening, but they fulfill their task well. Comparison to another more expensive brand specializing in merino wool products: these are less pleasant to the touch, but after a year of use their condition is much better - they will still serve me well.

Only 2 stars because…

2 stars only because very fragile. After two 2-day treks, the seams gave way. Underwear so no exchange or refund 😢

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.

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.
