A year - round hit, the Women's All - Season Classic Long - Sleeve Merino Base Layer is a must - have for fall or summer backpacking. It uses Core Spun technology, where Merino is wrapped around a nylon core. This not only gives it extra durability but also keeps the super - soft, responsibly sourced Merino next to your skin for ultimate comfort. The raglan sleeves remove shoulder seams, so it's incredibly comfortable under your backpack. And the smooth merrow stitching that goes from the side to the front makes you look as great as you feel.

How to use: Simply wear this base layer directly against your skin before putting on other clothes when you go backpacking in fall or summer. It can also be worn alone in mild weather. Things to note: Avoid sharp objects that may damage the fabric. Although it's durable, rough handling can still cause wear and tear. Maintenance advice: Wash it in cold water with a gentle detergent. Don't use bleach or fabric softeners. Hang it to dry to keep its shape and softness. This way, your base layer will stay in good condition for a long time.
