\"Today\'s synthetics are awesome. Nearly as light and packable as down, they excel in a wide range of conditions, making them perfect for climbing in the Northwest. I carry both down and synthetic jackets in my kit for most climb. That way I can mix and match on the mountain.\" \r\n“A heavy insulation piece should keep you warm in the coldest conditions you expect to encounter. I look for insulation that’s oversized so it can fit over layers while being comfortably zipped. I prefer down to synthetic, as it’s much warmer for the weight. At 8,000 meters, every ounce matters.\"\r\n\"I\'m a big fan of wool products. The new wool fabrics are comfortable, itch free and machine washable. There\'s nothing that compares to wool for warmth when wet, breathability, and non-stink!\" \r\n\"Soft shells are great in cold, dry and windy conditions, and will also protect you in damp conditions when the situation arises. I\'ll wear a soft shell when I want a closer fitting and more active outer layer that still protects me from wind and breaths quite well.\"\r\n\"My softshell jacket is the most technical, athletically cut, and versatile layer in my kit. It functions as both a mid and outer layer depending on the weather conditions and my activity level. I look for a piece that has a good warmth to weight ratio, is highly breathable, provides protection from wind and light precipitation, sports a trim (and ideally flattering!) fit, inherent stretch for ease of movement, multiple pockets, and a large adjustable hood is absolutely mandatory!\"
