Quick Dry Merino Wool Base Layers

Quick Drying

Merino wool has natural moisture-wicking properties that help keep you dry and comfortable, even during intense activities. When you do get wet, merino wool fibers wick moisture away from your skin, drawing it to the surface of the fabric where it can evaporate quickly. This quick-drying feature helps to prevent chafing and discomfort caused by prolonged exposure to damp clothing. That means you can focus on enjoying your latest adventure, with your clothes being the last of your worries.

When it comes to size and fit considerations for Merino wool base layers, it's important to keep in mind that they should fit snugly against your skin without being too tight or restrictive. Merino wool is a highly stretchable fabric that is designed to move with your body, and a close fit helps to maximize its temperature regulating properties. 

To ensure the best fit, we recommend you consult our comprehensive fitting guide and take accurate measurements of your body.  When taking your measurements, use a soft measuring tape and ensure that it's snug against your body without being too tight. This will help you select the right size for your body shape so your base layer fits you perfectly!

Find My Fit

Merino wool is an excellent insulator and can trap body heat to keep you warm in cold weather. At the same time, it's also highly breathable, which means that it can allow excess heat and moisture to escape from your body, preventing overheating and discomfort. This unique combination of insulating and moisture-wicking properties makes Merino wool an ideal choice for cold weather base layers. This makes Alpine Fit’s Merino wool base layers the ideal choice for enjoying winter sports and activities.

Yes, Merino wool base layers are naturally resistant to odors due to the antibacterial properties of the wool fibers. Merino wool actively prevents the growth of bacteria and can help keep you feeling fresh and odor-free. This makes Merino wool base layers a great choice for extended outdoor activities.

Merino wool base layers are easy to care for and maintain with a few simple guidelines. It's generally recommended to wash them in cool water and avoid using harsh detergents or bleach, which can damage the wool fibers. Instead, use a gentle wool-specific detergent or a mild soap, and avoid using fabric softeners or dryer sheets, which can leave a residue on the fabric and diminish its moisture-wicking and temperature regulating properties. When drying, lay the base layers flat to avoid stretching or distortion, and avoid using high heat, which can cause the wool to shrink. By following these instructions, you can ensure that your Merino wool base layers remain soft, comfortable, and effective for years to come.
