Hiking in cooler temperatures, such as those in the 30s and 40s Fahrenheit (around 0-10°C), can be a refreshing experience. However, the key to enjoying your hike is dressing in layers to stay warm, dry, and comfortable. Proper clothing is essential to regulate your body temperature and protect yourself from the elements.
In this guide, we’ll walk through the different layers and types of clothing you should wear when hiking in 30-40 degree weather.
Base Layer: The Foundation of Your Clothing
The base layer is the first layer of clothing that comes into direct contact with your skin. Its primary role is to wick moisture away from your body. Whether you’re sweating from the exertion of the hike or exposed to light rain, the base layer helps keep you dry and warm.
Material: Choose Moisture-Wicking Fabrics
For the base layer, opt for fabrics that wick moisture away from your skin. The most common materials are merino wool, synthetic fibers (like polyester), and silk. Cotton is a poor choice for hiking in cooler weather because it traps moisture and loses its insulating properties when wet.
Merino Wool: This natural fiber is an excellent choice for colder temperatures. It keeps you warm, even when wet, and is also breathable. Merino wool is soft, comfortable, and odor-resistant, making it ideal for long hikes.
Synthetic Fabrics: Materials such as polyester and nylon are quick-drying and effective at pulling moisture away from the body. They are usually more affordable than merino wool and can perform just as well in keeping you dry.
Silk: This fabric is lightweight, breathable, and moisture-wicking, though not as durable as merino wool or synthetic fibers.
Types of Base Layers
Shirt: A moisture-wicking long-sleeve shirt is a good choice. It should fit snugly to allow sweat to move away from your skin. Look for shirts that offer UV protection if you are exposed to sunlight for long periods.
Bottoms: Opt for moisture-wicking leggings or long underwear. These should fit comfortably without constricting your movement.
Undergarments: Choose moisture-wicking underwear made of synthetic fabrics or merino wool. Avoid cotton to prevent chafing and discomfort.
Mid Layer: Insulation for Warmth
The mid layer is designed to retain body heat while still allowing moisture to escape. Depending on how cold the weather is, this layer can be adjusted to provide more or less insulation.
Material: Warmth Without Bulk
The best mid layers for 30-40 degree weather are those that provide warmth without too much bulk, allowing you to stay active while regulating your body temperature. Common materials include fleece, down, and synthetic insulation.
Fleece: Fleece jackets are a popular choice for mid layers. They’re lightweight, breathable, and offer warmth without being too heavy. Fleece is also fast-drying, which is important if you get sweaty during your hike.
Down: Down is a natural insulator that traps air to keep you warm. However, it loses its insulating ability when wet, so make sure you have a waterproof outer layer if you choose down. Down jackets are typically lightweight and packable.
Synthetic Insulation: Synthetic options, such as PrimaLoft, provide warmth even when wet and are often more affordable than down. They’re perfect for cooler, damp conditions.
Types of Mid Layers
Jackets: A fleece or insulated jacket works well as a mid layer. Look for one with a full zip for easy ventilation when you get too warm.
Sweaters or Pullovers: A lightweight merino wool sweater or pullover is another good option. It’s especially useful when you need more warmth without the added bulk of a jacket.
Vest: If you tend to overheat during physical activity but still need some warmth for your core, a vest is a great choice. A fleece or synthetic vest provides insulation without overheating your arms.
Outer Layer: Protection Against Wind and Rain
The outer layer, also known as the shell layer, serves to protect you from wind, rain, and snow. In 30-40 degree weather, conditions can change quickly, so having a reliable outer layer is essential.
Material: Windproof and Waterproof
Look for jackets and pants made from waterproof or water-resistant materials. A breathable fabric like Gore-Tex allows moisture to escape while keeping rain and wind out, helping to regulate your body temperature. Other options include nylon and polyester with water-repellent coatings.
Waterproof/Breathable Jackets: A lightweight, waterproof jacket is a must. It should be durable enough to withstand the elements, and breathable to prevent overheating. A jacket with adjustable hoods and cuffs will help keep the cold and rain out.
Waterproof Pants: If you expect heavy rain or wet conditions, a pair of waterproof pants can keep you dry. Choose pants that are lightweight, breathable, and can be easily removed or adjusted depending on the weather.
Types of Outer Layers
Jackets: A waterproof jacket with a hood is essential. Features like underarm vents for breathability and adjustable cuffs are great for staying comfortable.
Pants: Waterproof pants will keep you dry in rainy weather. Look for pants with zippers or ventilation to regulate temperature.
Windbreaker: If there’s no rain expected, a lightweight windbreaker jacket can protect you from chilly gusts of wind while remaining breathable.
Footwear: Keeping Your Feet Warm and Dry
Choosing the right footwear for hiking in cold weather is crucial. Your feet are likely to get wet, either from snow or crossing streams, so insulation and waterproofing are key.
Material: Insulation and Waterproofing
Waterproof Boots: Look for waterproof hiking boots with a breathable membrane, such as Gore-Tex, to keep your feet dry while allowing sweat to escape.
Insulated Footwear: Insulated boots provide warmth, which is important when temperatures are in the 30s and 40s. They’re especially useful if you’ll be hiking through snow or on wet, muddy trails.
Warm Socks: Wool socks are ideal for cold weather hiking. Merino wool is soft, insulating, and moisture-wicking, making it a perfect choice for long hikes in chilly weather. Avoid cotton socks, as they retain moisture and can lead to blisters.
Types of Footwear
Hiking Boots: Insulated and waterproof hiking boots with good ankle support are a must for cold weather. They should have a solid tread for traction on wet or icy surfaces.
Trail Runners: If you prefer lighter footwear, trail runners can work well for mild conditions. Just make sure they are water-resistant, as the 30-40 degree weather can be wet.
Boot Gaiters: If hiking in snow or muddy conditions, gaiters can help keep snow and debris out of your boots and socks.
Accessories: Additional Protection
Even in cooler weather, accessories can make a significant difference in staying warm and comfortable.
Hats and Gloves
Hat: A moisture-wicking hat can help keep your head warm and dry. A beanie made of wool or a fleece hat is ideal. If it’s wet, a waterproof hat will help protect you from rain or snow.
Gloves: Gloves are essential in 30-40 degree weather. Opt for insulated, waterproof gloves to keep your hands warm and dry. If the weather is dry, a lighter pair of fleece gloves may be sufficient.
Neck Gaiter or Buff: A neck gaiter or a buff can help protect your neck and face from wind and cold air. Some buffs can be converted into a hat or face mask if the weather turns colder.
Sunglasses and Sunscreen
Even in cooler weather, it’s important to protect your eyes and skin from the sun. Snow can reflect sunlight, intensifying its effects.
Sunglasses: Wear sunglasses with UV protection to shield your eyes from glare.
Sunscreen: Apply sunscreen to exposed skin, even in cooler temperatures. Sunburns can occur year-round, especially in high altitudes or on snow-covered trails.
Layers for Flexibility
One of the key aspects of dressing for hiking in 30-40 degree weather is layering. Layering allows you to adjust your clothing as your body temperature fluctuates during the hike.
Start with a base layer to wick moisture away from your skin.
Add a mid-layer for warmth, depending on how cold it feels.
Finish with an outer layer to protect against wind and rain.
Conclusion
Hiking in 30-40 degree weather is a great way to enjoy the outdoors, but it’s essential to dress appropriately to stay comfortable and safe. Focus on moisture-wicking base layers, warm mid layers, and waterproof outer layers to protect against the elements. Don’t forget about your feet, hands, and head—keeping those parts warm and dry is crucial in cooler temperatures.
By dressing in layers and choosing the right materials, you can enjoy your hike without feeling too hot or too cold. Stay comfortable, stay dry, and enjoy the beautiful scenery!
