Purchased new at MYSTERY RANCH TOKYO. I took it on two hikes, hidden in my pack, but it never rained, so it's practically unused. There are packing wrinkles, but there are no noticeable stains or scratches. The size is compatible with 45L-70L packs. The MYSTERY RANCH PACK FLY M is a water-resistant dark gray rain cover featuring an opening with an elastic band. - Model Name: PACK FLY M - Brand Name: MYSTERY RANCH - Color: Dark Gray - Features: Opening with elastic band - Size: M Thank you for looking.
