Helly Hansen Active Flow 1/2-Zip Top - Men's

The difference between fun, or cold and wet.

The last thing you want when you're a few days in on your expedition is to be saddled with a wet, soaked baselayer. Make sure that isn't you by throwing on the Helly Hansen Men's Active Flow 1/2-Zip Top. The Lifa Flow and Life Stay Dry technologies work together to keep you warm and to wick moisture away from your body, ensuring you don't freeze every time you stop moving. The 1/2-length zipper lets you easily take this layer off, on the off chance you ever want to wear something else.

Great touring piece

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Living in Utah where the temps are in the 20s-30s most of the time, this is my everyday base layer. Very lightweight and comfortable, warm when you need it but really breathable when you are working hard hiking around. The chest zip gives you that little extra cool when you are sweating

Spending a lot of time traveling up and down in the North Cascades I end up going through little micro-climates of warm and cold, and having proper layering pieces is essential to not getting cold, wet, tired, cranky, etc.

The Active Flow top does a great job at maintaining body warmth while transferring that moisture away from my skin. I can keep it in the pack till I need it without sacrificing weight, and it fits like a glove for minimal impedance when I'm trail running.
