A technical, sporty Rafiki body warmer that you'll love taking on climbing trips all year round. It'll have your back in any situation - whether you're belaying a fellow climber on his project, catching up on the gondola, chatting with friends about your next climbing plans, or heading out to the rock face in the cold for a nice pace. The jacket is filled with Du Pont's eco-friendly Sorona corn fiber, which has great insulating and functional properties. Honestly, you won't feel much difference between Sorona and down in terms of insulating properties, plus this fill resists moisture and dries quickly, so you don't have to worry about getting a little wet. Thanks to the stretch gussets in the armpits, you'll feel comfortable in this jacket even when you're doing vigorous activity. There's also a compression bag for packing or the popular climbing difficulty chart.
