Product Customer Reviews
Comfortable, soft, warm. And when hiking, you can wear them for at least 3 days without worrying about bad odors. Hand washable and dries quickly even when hung on a backpack. I'm buying two and rotating them.
perfect for avoiding friction, very good product
The boxers are well made and comfortable, but in the conditions I was in in the mountains, I didn't feel much difference from regular models. Despite this, they didn't disappoint me - they fit well, don't rub and dry quickly.
Perfect for treks and hikes, when traveling. Dries quickly
Good merino content.
Perfect so I bought the same one in black.
Very useful on a multi-day hike, doesn't stink and wicks away sweat
very comfortable
I don't let them go, they wick away sweat well and can be worn for several days without any odor. They dry quickly after washing, great equipment for long treks (in my case the Camino de Santiago)
Very good to wear
ideal for bushcraft and can also be used when it is very cold. Hand wash advice.
The underpants are a little longer, so your thighs don't rub against each other. They are very comfortable to wear and wick away moisture well. However, the waistband is a little thin and often gets tangled up.
The underpants fit really well and were able to demonstrate their quality during a crossing of the Alps, but unfortunately they are completely worn out after 6 months.
good
very very good product, comfortable in any activity
Size Guide

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.
