Like Icebreaker and Smartwool, but half the price. Can't go wrong.

@ Luke M I would suspect your pants suffered from a moth infestation. This happened to me a few years ago. Before putting them away for the summer I aired out my Devolt base layer long johns, 100% merino. But I did not wash them. Next winter the crotch area looked like swiss cheese. Wool moths prefer them parts contaminated with 'DNA-material' over clean wool.

Minus half a star because the collar feels as if it has an 'odd shape' (rides a bit high on front which irritates my neck hair, maybe waxing the neck hair is a good solution?) Excellent value for money, these are incredibly comfortable and do exactly what they are designed to do! Not sure how I have managed to cope during previous cold weather ventures without these. Edit 1 : After about a year of occasional outdoor use (being a base layer underneath trousers and a shirt), many holes are appearing at random places on both the shirt and long johns. Edit 2 : (2023) Thank you to Mauritas W. I had not considered moths when storing these; will take those suggestions and precautions towards all merino gear I have especially these. Luckily I have managed to repair the holes as I want to keep these going due to the great quality and performance. Still seeing use in the colder months to this day, using them more frequently in day-to-day activity on top of outdoor use.
