Men Down Vest Polyester Light Grey Outer Navy Blue Nylon Inner Down Puffer.

Lining is nylon 

The tan side is polyester and will repellent water 

Down filled

The colors are totally rad

I would wear it tan or navy side out

Excellent condition

I would wear this reversible sometimes because both colors are so great, and when it’s raining I would use the blue nylon as the exterior. I don’t think it’s intended for reversing because the labels on the upper back but I would do it anyway
