I have had my Helly Hansen long Johns for 4 years. I live in Canada and have a condition that doesn't allow me to control my body temperature easily. I wear long Johns as soon as it hits 5° outside, so I spend most of my winter wearing long Johns.

I find Helly Hansen to be the warmest gear on the planet! Trust me, I've tried a lot of products claiming to be warm that just are not! They have held up exceptionally well to washing and wearing. They still look fairly new after 4 years - I only have 2 sets in rotation.

It also helps that my brother is military and he recommended this as a top brand. It is what they use out in the feild ;)

I couldn't live without my Helly Hansen's!!
