Utilizing an ultra-light Nuyarn 125 merino fabric with matching eyelet knit strategically placed underarm for increased breathability, there is no better combination of performance, comfort, and durability in the world.
“For I do not like baselayer slim the Boulder 125 1/4 Zip is not so tlght, as the most camparable long sleeves.
(Very) long cut arms are well done because of the thumb-holes.
The think material works perfectly, espacially the extra thin hile-knitted unser the pits for better ventilation.
I have 2 of them (and a longjohn) and do not use others since I owe them, except in very cold conditions below -10/-15 ° celsius.
And not only boring depressing black or neon-navy :-))) - thank you, Artilect, für the colors!”
