Lightweight long underwear is for warmer temperatures and higher intensity activities, and heavyweight long underwear is for colder, more stationary activities. While it’s easy to get lost in the details, the most important factor to consider is the weight or thicknesses. That being said, there are a daunting amount of long underwear brands and varieties out there. This prevents the chills from setting in and lowering your core temperature.Įssentially, your base layer functions as a second layer of skin, and many people wear their long underwear 24/7 during a winter camping trip.Īnd yes, things get quite ripe after a few days. It works by both providing a layer of insulation and, just as importantly, by wicking sweat and moisture away from your skin. Made from either wool (usually merino) or polypropylene, your base layer should snugly fit your body.

So let’s look at a simple layering system to prepare you for these extremes. The inverse is also true: if you don’t have warm enough clothes, you will be cold. Excessive sweating can cause you to become dehydrated or, because that sweat can work to chill you, hypothermic. If you aren’t prepared you can become extremely uncomfortable and overheated.

Others need a full down jacket to stay warm. For instance, skiing in -20 temperatures will cause some people to sweat, even if they’re wearing only polypropylene and a windbreaker. It varies from person to person, but the temperature extremes between rest and movement can be drastic. You need to dress so that you don’t freeze while sitting still or taking a rest, and in a way that makes it easy to shed layers when you move and your body heat rises. It’s about dressing in a way that allows you to move between extremes.

Watch a seminar on winter camping Winter camping gear and clothing: How to layer and stay warmĭressing for winter camping is not just about wearing enough clothes to stay warm.

With these basics in mind, let’s dive deeper into these topics and get you ready to explore the Boundary Waters in winter. More clothes, more food, more hot chocolate! If there’s one thing to remember about winter camping, it’s that you need more of everything. Many of these can be unexpected, such as overheating or negotiating open water when it’s -30 below outside. Safety! From frostbite to managing your body temperature, traveling in subzero temperatures presents all sorts of safety concerns.But your gear selection is critical in winter! Be sure you check and recheck your gear and consult with others before heading out. However, in summer you can get by with the wrong kind of sleeping bag or last a week without a jacket to keep you warm. This is almost the opposite of those sun-drenched summer days! During the month of January, you’ll only have about eight-and-a-half hours of daylight, which means two-thirds of the day will be in darkness. Staying warm takes energy, so you’ll need to keep your body fueled by consuming more calories than you would on a summer trip.

Even if you’re not sweating, be sure to drink at least two liters of water throughout the day. Your body is doing a lot to stay warm and move, and even if you’re not sweating, it needs a lot of water to function properly. This is a big one that’s easy to overlook. The cold also means you’re going to need to know how to manage layers in order not to freeze - or overheat. Same with sleeping bags (unless you invest in a bag that’s rated either -20 or 40 below). For instance, instead of one sleeping pad, you probably need two. This might seem obvious, but this simple fact will drastically change how you travel. Winter in the Boundary Waters is a magical experience!
