I purchased this from Amazon in March of this year. I liked the design and how it felt, but I'm selling it because the lack of side pockets was inconvenient for my needs. I used it about three times and washed it in my home washing machine each time. There's a pocket on the back that fits a smartphone. Here's the product: https://amzn.asia/d/hM5HhTm (It seems to be out of stock now) - Brand: asics - Size: L (Waist 83-90cm) - Color: Turquoise - Design: With back pocket - Features: With drawcord Thank you for looking.
