7 Best Base Layers 2022/2023

For the outdoor athlete, a layering system is essential to staying comfortable in all weather conditions. Choosing the best base layers is vital for keeping you warm and dry as you go about your adventures. The best base layers are breathable, have moisture-wicking capability, and have a comfortable fit.

Base layers come in different fabric weight categories – lightweight layers, midweight layers, and heavyweight layers—the heavier the weight, the warmer the base layer. Depending on the time of year and the activity you are participating in, you may need lightweight base layers for warm-weather activities like hiking or running or heavyweight base layers for cold-weather sports like skiing.

When choosing the best base layers, it is essential to consider the fabric composition and fit. Cotton is not ideal as a base layer because it absorbs moisture and traps it next to your skin, which can lead to chafing and irritation. Instead, opt for base layers made of synthetic fibers or wool materials that are naturally moisture-wicking. Look for base layers with flatlocked seams to reduce friction and skin irritation, and make sure the fabric is stretchy so that it moves with you as you are active.

Considering the best base layers to keep you comfortable and dry on your next outdoor adventure, consider these top 7 options.

Without further ado, let’s get started!

Base Layer Buying Guide

Layering System

A sound layering system will keep you comfortable and dry in all weather conditions. Layering allows you to stay active for more extended periods and adapt to changes in temperature, making it an essential part of any outdoor wardrobe. A good layer system includes a base layer, a mid-layer, and an outer layer. The base layer sits next to your skin and is responsible for wicking moisture away from your body and regulating temperature. The mid-layer provides insulation and is designed to keep in the heat captured by the base layer. Finally, the outer layers protect you from wind and rain, keeping you dry and comfortable.

Choosing a Base Layer

When choosing base layers, a few key considerations must be kept in mind.

Warmth

Base layer warmth comes in three categories – lightweight, midweight, and heavyweight. Lightweight base layers are best for warmer weather and high activity levels, while midweight layers are best for cooler weather or low activity levels. Finally, heavyweight layers offer the most warmth and help to regulate your body temperature even in extreme conditions.

Material Type

Base layers are typically made from merino wool, synthetic fibers, or a combination of the two. Merino wool is soft, and lightweight, and naturally wicks moisture effectively away from the body. Synthetic base layers are more affordable and durable but do not regulate temperature as well. They are, however, very good at wicking moisture.

Synthetic Base Layers

There are many synthetic fabrics to choose from, so it’s best to read reviews and product descriptions carefully when shopping for a base layer. Some common synthetic fabrics include nylon, polyester, spandex, elastane, Thermolite, and Coolmax. Synthetic base layers have good moisture-wicking capability and durability.

Wool Base Layers

Wool layers are a great choice if you’re looking for a base layer that will regulate temperature and keep you comfortable in all weather conditions. Merino wool baselayers are popular because they are soft, comfortable, breathable, and have good moisture management abilities. It also offers odor resistance and natural sweat-wicking capabilities.

Fit

Most people prefer a base layer to be tight-fitting. However, some people prefer a looser fit for added comfort. Depending on your desired warmth and planned activity level, consider a thermal base layer that is loose-fitting or stretchy.

Breathability

Base layers optimized for breathability will allow sweat to evaporate quickly, keeping you dry and comfortable. It would help if you looked for a lightweight base layer designed with mesh or other breathable fabric panels to ensure maximum airflow around your body.

Durability

Because base layers are exposed to lots of wear and tear, choosing high-quality materials with good stitching is best. Seems should be reinforced, so they don’t tear easily, and the fabric should have good abrasion resistance to prevent pilling.

When shopping for a base layer, it’s best to read product reviews and compare different brands and materials to find the best fit for your needs. With a suitable base layer, you can stay active and comfortable in all types of weather!

Drying speed

Depending on the activity, drying speed can be an important purchase consideration. Some activities, like hiking or skiing, require that your base layer dries quickly so you can continue your day without feeling too cold or wet. Choose synthetic base layers if you’re looking for fast-drying and moisture-wicking capability.

Merino Wool Care

Merino wool is a popular material for base layers because it is soft, comfortable, and has excellent moisture management abilities. However, caring for a merino wool layers requires some special considerations. When washing merino wool, use warm water and a gentle detergent. Never put your merino wool layer in the dryer, as this will cause it to shrink. Instead, lay it flat or hang it to dry after each wash. You can also add some natural fabric softener to increase the softness and decrease pilling. With proper care, your merino wool base layer will last for years!
