I like that the Charles River vest is made from recycled materials. If I can reduce waste, including wearing clothes like this thats made from recycled plastic bottles, Im all for it. I thought I was receiving the plus size medium but received a medium. So this vet is too tight if I zipper it. But it looks stylish still unzipped. So thats how Ive had to wear it. It still gives me warmth, obviously not as much as if i wore it zippered. The black with the grey zippered pockets looks nice and compliments most of my clothing colors.
