Something from OV that isn't borderline flimsy in their quest for the ultralight & performance combo. These are stout and should be perfect for some frigid winter backpacking trips.

Size up
I regularly use Exofficio and Paka boxers and these are noticeably thicker & heavier.
Maybe they're best for winter/shoulder seasons?
My first impression is they are very well made, but noticed they tend to ride down in the back (maybe it's my body 🤷🏻♂️).
My usual size is XL, but I followed the sizing advice on this one and ordered the 3XL and the fit feels right (aside from low riding).

Not trail tested yet
I bought, wore for a day. Did not hike in them but on a hot day they were good at keeping temp lower than other everyday boxes.
Have not given it the true guy out hunting for 4 or 5 days where you wear regular then back to front then turn inside out and repeat with turn around and you are fresh for 4 days.
Seriously, I love every product I have bought from OV I'm sure these will be good in the field.
