The perfect layering companion for skiing and cold-weather hiking, the women's REI Co-op Midweight base layer half-zip top offers warmth in the cold and easy venting thanks to a front zipper.

• Recycled polyester/spandex has a smooth face so layers slide on easily, and is peached for a supersoft next-to-skin layer
• Fabric wicks moisture and dries quickly to keep you comfortable
• Partial zip neck to dump heat and provide ventilation if you need a little cooling down
• Spandex adds the right amount of stretch combined with underarm gussets to maximize your range of motion
• Flatseam construction reduces bulk and chafing, and rolled-forward shoulder seams prevent abrasion from pack straps
• Thumbholes hold sleeves in place and help seal warmth in
• UPF 50+ rating protects against sun rays
• Fair Trade Certified™ factories promote safe working conditions and sustainable livelihoods
