The key to staying comfortable in winter conditions is mastering the art of layering. This system allows you to adjust your clothing as your body temperature changes during your hike.
Base Layer: Start with a moisture-wicking layer next to your skin. Ideal materials include Merino wool blends, such as those in Icebreaker ZoneKnit, or synthetic fabrics like those used in Arc'teryx Rho. Avoid cotton, as it retains moisture and can lead to hypothermia.
Mid-Layer: This is your insulating layer. Synthetic, down, wool, or a blend works well here. Choose a thickness appropriate for the temperature and your activity level. For example, if the temperature is between -5°C and 10°C, a synthetic puffer like the Arc'teryx Atom is an excellent breathable option. For colder temperatures, the Norrøna Trollveggen Superlight Down Jacket, filled with RDS-certified 850 goose down (ensuring the down is ethically sourced and provides superior insulation), is a lightweight and warm choice. For more moderate temperatures, such as in spring or autumn, the Patagonia R1 Fleece is a cosy technical option with excellent moisture-wicking properties to keep you dry and warm with minimal weight.
Outer Layer: Your final layer should be waterproof and windproof. Look for breathable materials like GORE-TEX® to prevent overheating. Marmot Minimalist Gore-Tex Jackets and Pants are a good lightweight option, providing wind and water protection without the bulk, thanks to GORE-TEX Paclite®.
Accessories: Don't forget accessories! Waterproof DexShell Gloves & Socks and a Buff Neck Warmer are essential for protecting extremities.
