Notes About Aerogel:
We chose to use Aerogel in our gear because of its light weight, flexibility, and extreme compression resistance. Compression resistance is important here. Insulation that’s compressed for long amounts of time will slowly leak warmth. That’s what makes Aerogel so unique: Its insulation actually retains warmth even during extreme levels of compression, like when it’s on the bottom of your feet on the ground. Aerogel is unique in that it retains on average 96% of its original thermal performance under pressure, meaning that no matter how hard you grip, or how much weight you apply, it will start warm and stay warm throughout your day.
