No one really likes the cold, not even Finns who have heat intolerance in their genes (seriously). That’s why my mom invented dressing up in layers to keep humankind warm, but not look like the Michelin man. There are a few schools out there: The Naturals vouch for different types of wool, where Merino is the king of wools. The Commandos are plain crazy and usually take the bus after the weather gets cold and then there are the Techies, who like synthetic fibers lovingly caressing their warm and sweat-free bodies.
The purpose of base layers is to act as the second skin right on top of your own. Their job is to keep your skin as dry as possible, letting your own body hair create the teeny-tiny layer of air around you, since air is one of the best insulators in existence. You doubt my word? Guess what’s the insulator in a thermos can? Yeah, it’s air. The closer and tighter (to a point) the base layer is, the better it works in pulling out the moisture. Merino wool does this naturally, but the Techies have gone further and I’ve used Helly Hansen’s base layers for nearly 20 years with very good experiences.
The company’s current technology, called LIFA is a two-layer construction in itself having to different weaving techniques in the fabric. With this new material, they have big promises. Sometimes they even manage to sound like shampoo commercials with their “XX% faster riding” comparisons. But they have a few good points: LIFA dries faster than older Helly Hansens (which were fast to dry anyway), they are non-allergenic and thanks to their new process, the fabric is even lighter on your skin than before getting rid of that heavy and stuffy feeling you might get from poor-quality or old base layers.
LIFA comes in four types depending on the temperature: Warm, Cool, One and Dry. I usually go with the Dry version functioning from -15 to +15 degrees Celsius (that’s +5 to +60 degrees Fahrenheit for our American readers). Warm is for negative temperatures, Cool is for summer performance and One is similar to Dry but for a bit warmer climate (-10 to +25 Celsius).
I’m a very satisfied repeat customer with Helly Hansen and they even have a fly in their base layer pants!
ps. The people who use Helly Hansen’s regularly sometimes refer to them as “Smelly Hansens”, which is true if you keep them on for a longer period without washing (we’re talking about days here).
