Apparel: The overall system

These four layers are usually sufficient for most people, but if you tend to be colder bring one extra medium-layer that would be ideal for extra warmth around camp, such as a vest. When deciding what to pack, remember to bring enough clothes and accessories to ensure your safety and comfort, while not over-burdening yourself with items you probably won’t use. Ascent Outdoors  can help guide your purchases and layering strategy. 

• Base layer: manages moisture and wicks perspiration away from your skin. ( Capilene, Merino Wool)
• Softshell: should be a durable, comfortable, insulating and wind/water resistant layer that breathes well. 
• Hard shell: windproof, waterproof and breathable. (e.g. Gore-Tex, or similar)
• Insulating layer: should be down-fill or synthetic-fill and fit over all layers. (e.g. down, primaloft or polarguard)

Apparel: Upper Body

• 2x Changes of casual wear for time off of the mountain. Cotton is okay for this.
• 2x Synthetic t-shirts

• 1 Hoodless layer for colder days. 
• 2x Sports bras - Synthetic, preferably with minimal lycra (it holds water)
