Layering Up

Top 11 Best Women's Base Layer TopsLayering up is by far the best way to go in cold weather, and especially if you are doing activities where you might be active one minute and stationary the next. Layering allows you to remove and add clothing as your body temperature rises and falls, controlling your comfort level much like a central heating thermostat. If you rely on just a few key items to keep you warm, like a down jacket, then you will often have to decide between being too hot or too cold during outdoor activities.

Solid Foundations

To give you another analogy, base layers are like the foundations of a house. If you start with the best base layers and then build up your clothing layers from there, you are giving yourself a great start to stay warm and dry in the wild. And because base layer tops are designed to be worn close to the skin, they are incredibly soft and flexible to ensure you stay comfortable and are not restricted in your movements. Base layers help your body to maintain its ideal temperature by keeping you warm when it’s cold outside and cool when it’s warm.

How do base layers work?

Base layers trap warm pockets of air next to the skin when worn underneath other layers of clothing as well as wick moisture away to keep you dry. They are an easy way to add warmth to your arsenal of outdoor clothing without adding much weight or taking up space in your backpack. With superior wicking qualities, perspiration is transported away from your body and keeps the fabric light and breathable. Stretchy fabrics are often blended with insulating materials to give unlimited freedom of movement alongside thermoregulation.

How should they fit?

how to wear womens base layer topsUnlike other outdoor gear, base layers are designed to fit snugly against the skin and provide a close fit, covering the whole torso. This means air is trapped next to the skin and insulates your body. They’re thin-knit, so you can layer them with other items and even double or triple up your base layers.

How do you wear them?

Base layers can be worn solo, and are available in long and short sleeves. But the best way to wear them is layering them. In fact, they’re sometimes known as “undergarments” as people tend to wear them underneath other tops. When you layer them, it creates pockets of warm air between the layers, which is much more effective than just one thick layer. The ideal layering system is a base layer, a mid-layer (fleece or jumper), and an outer layer (outerwear).

Synthetic Base Layer Tops

Best Women's Base Layer topsSynthetic base layers are generally made of polyester or polyester blends. They’re designed for temperatures as low as -10 degrees in combination with other layers and outerwear.

PROS: They’re often used for sports in colder weather, as they have excellent wicking properties, are extremely lightweight and quick-drying, which makes them ideal for active pursuits. They’re relatively cheap compared to other types of base layers, and are generally machine washable.

CONS: They’re not so good in extremely cold environments, and they’re not antibacterial.

Merino Wool Base Layer Tops

Merino wool comes from Merino sheep, who have survived in very harsh conditions for centuries thanks to their special coat. Evolution has made their wool an excellent material for outdoor clothing and I have written about the benefits here

PROS: Like the sheep, you’ll benefit from a regulated body temperature, retaining heat, and staying cool. This makes them perfect for outdoor pursuits in the extreme cold (down to -20) and for changeable weather. They’re also naturally UV-resistant, wicking, and anti-bacterial (less smelly). What’s more, they retain their thermal ability even if they get wet.

CONS: Unfortunately, this plethora of benefits means they cost more and can be hard to find in your average outdoor store.

Bamboo Blend Base Layer Tops

This relatively new offering to the base layer world is made of bamboo extracts and blends such as bamboo merino.

PROS: They provide a tighter fit than merino and hold their shape well. They’re ideal for those who get skin irritations from wool. They’re quick drying, very hard-wearing, anti-bacterial, anti-static, and cheaper than merino.

CONS: However, as they’re pretty new to the scene, they’re not widely available at the moment, and some brands are performing much better than others under testing.
