Substantial. The Recycled Trucker Jacket is a heavyweight layer made from a thick recycled wool blend and roomy enough to toss over even your chunkiest sweaters. What’s up with the virgin poly? This item was mistakenly made with it instead of our usual recycled stuff. That’s not our style, but neither is waste, so we decided to let it stick around. Don’t worry, it still holds its weight in the trash-cleaning department.
