Product Customer Reviews

These boxers are great, the recommended size is perfect, they are comfortable, don't feel like you're sweating, don't smell.
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. 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.
Perfect RAS
comfortable, warm on the route
2 stars only because very fragile. After two 2-day treks, the seams gave way. Underwear so no exchange or refund 😢
GOOD
Top quality/price ratio
Top quality/price ratio
it doesn't pick up odors if you take care of it - nothing has rubbed off yet
Thumbs up
The first choice for mountain climbing
Perfect
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
Composition
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: https://support.decathlon.co.uk/how-to-maintain-a-merino-wool-garment
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.
