Rather than develop a layering system where the user adds and subtracts, Sierra Designs turned the layering paradigm "outside in." Its Outside-In Hoody has a wind-resistant nylon layer and a fleecy warm layer.
For high aerobic output activities, like ascending a peak, the user wears the smooth nylon on the inside to encourage breathability. For lower aerobic output activities, like taking a break at the summit, the user turns the garment outside in, and puts the warm, fleecy layer on the inside, increasing wind-resistance and reducing heat loss.
