Smartwool Merino 250 Crew

Smartwool Men’s Base Layer Top

Frequently Asked Questions

Maybe you’re just setting out on your backpacking base layer adventure or maybe you’re in the market for new base layers after your old ones have just worn out from too much love and use! Either way, let’s ask some pressing questions and get shopping!

• What do I need to consider for base layers?

◦ Choose a material, weight, and fit factors as you’re shopping for a base layer! Whether you choose natural or synthetic materials, choose something that fits your activity and doesn’t irritate your skin. You can choose between lightweight, midweight, and heavyweight each of which progressively adds more warmth and weight to your base layer. And lastly, you want to choose your fit factor: skin-tight, fitted, and loose or relaxed which can affect how the clothes wick away moisture from your skin.

• Should I carry extra base layers while backpacking?

◦ Yes! Carrying an extra set allows you to have one specifically for the trail and one for being in camp. If you’re an ultra-lightweight backpacker you can get by with just one set to alleviate the weight you’ll be carrying but having an extra set is always a good idea!

• Does a base layer need to include socks?

◦ Absolutely! You’ll need to carefully think through the type of socks you want to wear when out backpacking and consider it a crucial part of your base layering. Choose socks that will also wick away moisture from your feet to keep them from blistering or chafing as you hike!
