Arc'teryx Quick Drying Base Layers

Key features to look for

• Moisture wicking: moves sweat to the outer surface while also drying quickly; that lets you break a sweat without feeling clammy or chilled.
• Sun-protective fabric: Protect yourself from harmful UV exposure by choosing clothing with a UPF; a higher rating means better sun protection
• Quick drying: Materials that dry quickly keep you cool, comfortable and dryInsect repellent: treated with active ingredients to help keep ticks, mosquitoes and other pests at bay

Hike clothing fabrics

• Merino wool has fine fibers that make it soft, breathable, moisture-wicking, reasonably quick to dry and not prone to retaining odors.
• Polyester/nylon: Generally less expensive than merino wool, these synthetics excel at wicking sweat and drying fast, and many incorporate recycled materials 

Dress in layers 

• Start with a base layer that wicks sweat off your skin; this includes underwear, a bra, hiking shirt and hiking pants
• Add a middle layer to retain body heat in colder conditions; this could be a fleece jacket, an insulated vest or puffy jacket
• An outer layer, like a rain jacket, shields you from wind and rain
