I’m getting ready for a high route trip up in BC (Purcells). Historically prone to sustained periods of wet / cold weather. If the forecast is good I plan to take a more conventional lightweight clothing system that includes a down quilt and/or down jacket. Otherwise, I’m planning on having to hike through exposed high terrain regardless of weather, because we can only carry so much food and need to keep moving towards our exit.
So I’m trying to put together a system that gives me the insurance needed if I stay wet(ish) and can’t dry out gear, and will keep me warm if the wind is blowing and it’s 40 degrees and it’s raining and I’m hiking a 10,000 foot ridgeline.
So I made a photo, because it’s easier for me to visualize:

The items in the photo aren’t an exact match of what I’m planning on taking, but here’s the list:
Trekking Clothes (mosquitoes, bushwhacking in dense cedar/hemlock forests):
- long sleeve polyester shirt (Patagonia Sun Stretch)
- nylon pants (Patagonia Quandary)
Storm Clothes:
- wind jacket (Patagonia Houdini Jacket)
- rain gear (Montane Minimus 777 Jacket & ZPacks Challenger Pants)
Insulating / Camp Layers:
- BPL Cocoon 240 Quilt
- Patagonia Nano Air Vest
- Patagonia Piton Fleece Hoody
- Patagonia Lightweight Capilene Bottoms
Other:
- Merino midweight hiking socks
- ZPacks Challenger Gaiters
- OR Vert Gloves
- Salewa Mountain Trainer shoes
Thoughts on these specific item choices, esp. anyone who has experience with the Piton (or its competition) or Nano Air Vest (or its competition)? Replacing a down jacket with two layers (the fleece hoody and synthetic vest) irks me a smidge due to the added complexity but the need to stay moving in bad weather may necessitate it.
Also curious if anyone has found a shoe that has the tech performance of the Salewas with more cushioning / drainage. These are the most cushioned technical shoes I’ve worn, but I’m not a fan of the fact that they drain horribly after a river crossing.
Also for gram counters: the footwear/clothing/sleep insulation system in the photo weighs about 7.7 lbs…
