Great cool weather undies.
These are the ONLY pair of boxer briefs i own that roll. I dont get it? I even wasted money on a larger pair. $50 out the window. Horrible fitting underwear unless you have a concave waist so the top does not roll.
Hello Tony,
Thank you for your feedback. We are sorry that you are not satisfied with your boxer.
Your feedback will be forwarded to our design team in order to improve this product.
Regards,
Johanne
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!

Great value merino
These are designed to be closer fitting than men's underwear should be. But additionally the sizing is a mess. I wear 32" waist trousers quite comfortably but the medium size in these pants is far too tight and uncomfortably close fitting. Size Large has a waist band measuring 14 1/2 " across and requires a forceful stretch to attain 16" so not even the large size quite attain the 32" medium size claimed. What's going on here?
Fab. Light, soft and very comfortable at a great price..
For the price totally excellent and just as good as the top brands
Really comfy, great price
I bought a black pair in January 2022. I wear them three or four times a week when I go on walks (less than 5 km). The gusset have completed worn away and there are large holes!! I had to bin them. The wool boxer shorts are not fit for purpose. Do not buy them. I've lost my receipt so I assume I cannot ask for a refund (as it's still within the 2 year warranty period).
Very pleased with this purchase especially after a 6 hour hike. Merino pants offered plenty comfort & dryness on a hot day.
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
