A year - round hit, the Women's All - Season Durable Merino Long - Sleeve Classic Base Layer is ideal for backpacking in fall or summer. It uses Core Spun tech, where Merino wool wraps around a nylon core. This gives it extra toughness while keeping the super - soft, ethically - sourced Merino close to your skin for ultimate comfort. The raglan sleeves remove shoulder seams, ensuring great comfort when you're carrying a pack. The smooth merrow stitching runs from side to front, so you'll look as good as you feel.

How to use: Simply wear this base layer directly against your skin before putting on other clothes. It's great for backpacking or other outdoor activities in fall or summer. Things to note: Don't wear sharp objects that could snag the fabric. When wearing under a heavy pack, make sure the sleeves are properly adjusted for comfort. Maintenance advice: Wash it in cold water with a mild detergent. Don't use bleach. You can lay it flat to dry. Avoid wringing it out forcefully to keep the shape and quality of the Merino wool.
