Helly-HansenHelly Hansen Men's Lifa Stripe Crew Lightweight Breathable Moisture Wicking Thermal Baselayer, 998 Black - Medium

This men's base layer, from Helly Hansen, is designed to be like a second skin, wicking moisture away from the body and helping to keep you dry and comfortable- and it lives up to the hype! The top is of typical Helly Hansen quality. BUT- as I have found for all HH gear, it runs small (my husband is normally a Large and the X-Large is a good snug fit). It's super lightweight and breathable. Warm when standing still but breathable during activity. The top is a nice slim cut and looks good too. He is currently wearing it in the snow in Niseko Japan and it's keeping him very warm under a standard fleece. Machine washable and quick drying, so it's versatile as well.

Woth every cent fits perfect ,well made great colors on arm I highly recommend this Helly Hansen base layer ,also very confortable!

My husband loves these shirts. He wears them skiing and as an under layer in the winter. They are thin and soft. They didn’t shrink.

This base layer top would have been rated 5 stars with the exception being that the cuffs on the shirtsleeve were a little loose as my wrists measure 8-1/2 inches. I prefer the sleeve's cuffs to be a good snug fit so air and snow cannot travel upwards. I have several older base layer tops and the sleeves' cuffs are a bit longer and tighter.

Soft non-scratchy materialMy son is 510 and weighs 150 pounds and it’s a perfect fit with a tiny room to growI know this brand to fit small so consider sizing up

For such a thin shirt it helps to keep me warm better than I thought it would, even when soaked with sweat. The fabric breathes well and drys quickly in a breeze. It is a little bit stretchy and hugs my shape well and I find the white stripes down the arms fashionable. I bought two of them for kayaking but wear them when I am out exploring dry ground as well. I got them on sale but believe they are worth the regular full price.I would buy them again and recommend them for any activity where its important to stay warm when wet. One big plus is after it drys from sweating It doesn't smell like body odor like a cotton shirt does. Great for overnight kayaking trips.

The sleeve ends are not elastic making it impossible to get a proper fit when moving my arms.

I perspire a lot, particularly with exercise. Long ago I learned about the virtues of polypropylene. Any cold weather activity with cotton underwear is a sentence to being cold. I have tried many brands of polypropylene first layers. They frayed, they pilled, they tore and developed holes. Then I discovered Helly Hansen. Top price, but I had been disappointed by all others. WOW. Worth every penny. Years of use of their first layer with no cotton and I am warm and dry when snow shoeing, XC skiing, snow blowing and hunting. Use a second layer of standard polyester pile, and you can do single digit temps, with vigorous exercise and still be warm and dry. This is one item that going cheep doesn't work. When you are outside, wet and cold, price doesn't matter. Go for the top on this one. HH makes them well, and they last, and they work.
