The Difference Between Active and Static Layering

Layering is an important part of any outdoor activity, especially if you’re going to be facing unpredictable weather, colder climates, or harsh environments. And in some extreme cases, your survival can depend on not only what you wear but also on how you choose your outer layers. If you're new to outdoor sports like hunting, hiking, mountaineering, or extreme sports, you might come across terms like active layering and static layering. But what do these terms mean? Well, that’s what we’re going to tackle today! We’ll explain the difference between active and static layering, and give some of our tips for the best tactical gear to add to your arsenal.

Understanding Your Body

Understanding your body is super important because we all have different quirks when it comes to temperature regulation. Some people seem to radiate heat like a furnace, while others find themselves shivering at the smallest breeze. Knowing how your body reacts helps you choose the perfect outer layers to keep you cozy and comfortable. How your body behaves when active (working out, working hard, exerting yourself) and when static (relaxing day, sitting by the campfire, resting) should be noted and lead to your layering decisions.

Knowing how your body reacts to temperature differences is especially important if you’re going to be active. Keeping yourself comfortable with a 20 lb. pack on while walking on flat terrain or climbing a rough one is the most essential part of layering. Too many layers, and you cause yourself to sweat even more. Not enough and hypothermia or frostbite are a real risk.

Adapting to Your Environment

But it's not just about your body – you've got to consider your surroundings too. Temperature, wind, humidity – they all play a role in determining the ideal layering strategy. The goal? To have gear that's adaptable and versatile, ready to handle whatever Mother Nature throws your way. So you’ll need to consider where you are going to be and what you are going to do while layered. Think about the time you'll spend on the hike, trip, or training, the temperature, wind exposure, condensation, trail/terrain conditions, weather, and moisture exposure (rivers, lakes, rain).

Active Layering

Let's talk active layering. When you're on the move, you need layers that can keep up with you. That means insulation that traps heat while still allowing moisture to escape. Air is the best insulator, allowing for very slow heat conduction. The more air trapped between two bodies (our body, and air) the better insulation and less energy loss. So, you’ll want to look for base and mid-layers made from breathable fabrics that can handle your sweat sessions without leaving you feeling clammy and uncomfortable.

Wicking will be super important as a base layer for active layering. Wicking is a capillary action that moves liquid through a narrow space using opposite forces (like gravity vs heat) or the movement of sweat from your base layer/shirt to the outside of the garment. Basically, the more wicking a garment has, the quicker it dries. The breathability of a piece of clothing is also really important. This refers to the movement of air and vapor through a narrow space, such as fabric, or membranes. Most shells, or outer layers, will take your sweat and turn it into vapor, which then moves through the fabric to the shell's outside and dries out.

These two qualities will be crucial when it comes to choosing the right tactical base layers and mid-layer insulation. A mid-layer is especially important when in windy conditions, as wind without a shell to block it can simply swoop in and blow away the warmed insulated air. Mid-layers should be worn whenever the temperature becomes too low for comfort and you feel you need another air barrier between your waterproof and/or windproof shell (outer jacket, etc.) and your base layer.

Tip: It's easy to overdress and accidentally overheat yourself. If you’re just starting an activity, start slightly cold to prevent overdressing and heating since you will probably warm up pretty quickly as you become active. If you find that you’re still cold, that’s when you’d put on an active base or mid-layer to warm up.

Static Layering

Now, when it's time to take a breather, static layering comes into play. Here, the name of the game is heat retention. You want layers that'll keep you warm and toasty, whether you're lounging around camp or enjoying a well-deserved rest after a day of adventure. Think down jackets, insulated jackets, or good old-fashioned wool – anything that'll help trap heat and keep the cold at bay.

There are three key factors to consider when you are static layering or looking for a good static layer. The first is thickness – the thicker the garment, the warmer it will be. And most likely, the heavier to carry. If you’re going to be in an extremely cold environment during static times, then it’s best to have a thicker garment. The second aspect to consider is the weight-to-warmth ratio. Obviously if you are going to be traveling on foot, the lightest option you can find and afford to get the most warmth out of it will be important. Last, you’ll want to remember your limitations. Synthetic fibers can only be made so thick without them collapsing. Synthetic will never be as thick as down is, however, down is susceptible to humidity and condensation, making it a risk in wet environments.

Building Your Gear Arsenal

So, what should be in your tactical gear stash? Start with high-quality Merino Wool base layers – they're soft, breathable, and excellent at wicking away moisture. Add a versatile mid-layer like our TD Shaolin Hoodie – perfect for adding an extra layer of warmth without weighing you down. And for those active adventures, don't forget a sturdy synthetic jacket to keep the wind and rain at bay. When it's time to kick back and relax, reach for something thicker like a down jacket– it'll keep you warm and cozy no matter how chilly it gets.

Embrace the Elements and Enjoy the Adventure

Remember, finding the right gear is all about staying comfortable without weighing yourself down. By understanding the ins and outs of layering, you'll be ready to handle whatever the great outdoors throws your way. So go ahead, embrace the elements, and enjoy every second of your adventure!
