"In my system, I use a vest for insulation. The light loft of the Jetstream Vest is ideal for cutting the chill of an early morning. However, because I use the 90% Jacket primarily, I need the wind blocking ability of the vest in my system for when the wind picks up. The Jetstream Vest serves that purpose perfectly."
