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)
