1/ Midlayer: My preference here is also a quick-drying material that insulates well, such as the Speed Polartec Hoodie.
2/ Base layer: For me, the perfect base layer is a quick-drying material that still provides warmth when damp, like the Dryarn fabric.
3/ Hardshell jacket: The TLT GORE-TEX® Jacket offers rugged protection against wind and snow, yet – for a hardshell jacket – provides really good freedom of movement. This makes it an ideal ski touring jacket, and one which I wear all day on cold or windy days.
4/ Down jacket: A good down jacket that will pack down small is almost always worth adding to your backpack. In many cases, it provides your safety margin of error. In very cold temperatures I wear mine under my hardshell jacket.
5/ Ski touring pants: The TLT Dynastretch Pants are perfect both for cold and for somewhat warmer days. In particular, the exceptional freedom of movement and the warmth/moisture management characteristics make them my go-to touring pants. On really warm days, I use a slightly thinner pant, and in extremely cold conditions the TLT Dynastretch combines well with a base layer underneath.
6 & 8/ Hat & Headband: Depending on how temperature sensitive you are, covering your head almost always makes sense. I always wear a hat or headband underneath my helmet on descents to prevent my head from getting cold.
7/ Neck gaiter: In colder conditions, a neck gaiter can be quickly pulled up to provide warmth, without needing to stop.
9/ Gloves: For most ascents, the DNA Gloves are my first choice. To keep my hands warm on descents and as a safety measure I like to carry along a pair of warmer gloves.
10/ Socks: Close-fitting compression socks are essential to prevent the sock from slipping. Additionally, good moisture management is critical, especially in spring.
11/ Sunglasses & Glacier glasses: On climbs I almost always wear sunglasses – even on cloudy days, sunlight reflects back off of the snow into your eyes.
