Women's Aspect Quarter Zip Midweight Merino Wool Long Sleeve Shirt
ⓘ This product uses our old size guide



We took our bestselling Aspect Merino Wool Base Layer and added a classic quarter zip at the front to make an even more versatile base layer. Our midweight Aspect base layers feature an exclusive design that feels great next to your skin and keeps you warm, dry and comfortable. Designed for your active lifestyle, this top is durable and cut long so it stays tucked in. Discreet thumb holes keep your sleeves in place and disappear when you don't need them. This top is plenty warm, but thanks to Merino wool's natural breathability and the quarter zip, you won't overheat.
