Product Customer Reviews

Really great. Allows me to wear lightweight hiking trousers while still keeping my package at a comfortable temperature. A must for outdoor winter activities.
Hi James,
Thanks for kind review!

These boxers are superb! I work as a sports coach and outdoors instructor, therefore i'm very active. These are warn when it's cold, cool when it's warm and seriously comfy!! No chaffing, even when wet and they don't get stinky!! On a recent work trip to Lanzarote I wore them all day in the heat and they were great! I ran, walked and even swam in them and they held their shape and dried really quickly. I can't recommend them enough!

Great
Extremely comfortable, sizing good.
Really wanted to like them, but wool is not very comfortable (a bit itchy), very very thin and the waistband is really tight - seems to be getting tighter with washes! After 3 weeks, they are now in the back of the drawer, to be used in the event of emergency.
Very warm and comfortable
Nothing really to complain about, these are really good for hiking at the money.
Great product, great price
I'm very pleased with these and will be buying more in future. They are great quality and very comfortable.
Bought these for my boyfriend and he said they’re very comfy and would definitely purchase again.
The elastic strands started protruding out and getting isolating from the elastic band after the third wash(normal machine wash with liquid detergent without tumble drying ) as per instructions

Awesome quality, love them, very comfortable, wicks off all the moisture that builds up, and also gives a soft feeling
Добро качество, еластичност, мекота. Всъщност най-евтиния продукт от този вид, който открех да се предлага към момента. Имам и по скъпи, които не бих казал се различават забележимо по качество.

Малко са скъпички, но за мен е най-доброто особено за дълги преходи. Стоят стегнато и фиксирано. Крачолите са достатъчно дълги, че да предотвратяват протриване. Не спарват, не се вмирисват и досега нямам скъсан чифт. Ако не бяха толкова скъпи щях ежедневно да съм с такива.

Size Guide

Additional Product Information
Composition
Main fabric
- 86% Wool
- 10% Polyamide
- 4% Spandex
Sizing and fit
These boxers have a fitted cut for enhanced moisture transfer to the outside of the fabric.
Origin of the wool
We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. We have full traceability, which allows us to guarantee the origin of the wool.
Durability
There is a BETA-SPUN yarn structure, i.e. the merino wool fibers are coated with a fine sheath of polyamide filaments to protect them from rubbing and cuts, without affecting the properties of the wool.
Advice before use
To make the component feel softer, don't hesitate to wash your boxers before 1st use.
How to wash your merino wool boxers?
Machine wash your merino wool boxers at 86°F on a normal cycle, preferably with a liquid detergent. Dry flat and NEVER tumble dry unless you want it to shrink by 1 or 2 sizes! For more information: https://www.forclaz.fr/conseils/comment-laver-mon-tee-shirt-de-trek-en-laine-merinos-tp_1550

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 backpacking in the Canary Islands for 2 weeks, followed by 3 weeks on the GR10 route in the Pyrenees.
