Coalatree Camper Hooded Jacket

Coalatree Camper Hooded Jacket Black Tag is a size Large, however I feel like this Jacket is more of a medium or a small even. I bought this for a camping trip in the fall and took it with me to use at night but unfortunately it never fit me to be able to zip it up, so it's hardly been worn. Still in great condition. Jacket does compact into its own pouch. Weight 14.4 oz Spot clean recommended. When necessary, machine wash delicate with gentle detergent, hang dry. Website says it can be worn up to -20 º. However I feel it's better for warmer winter temperatures.
