PORTVEL Pants Size: 2 These are pants made with eta PROOF (eta Proof). I bought them at a used clothing store, so they show some wear, but that adds to their character♪ Also, as you can see in the second photo, there is a hole in one place. However, it's right behind the pocket fabric, so your skin won't be visible. --Eta® Proof-- A traditional performance cotton from the UK. It's a functional material that maintains the breathability and comfortable feel of cotton while also providing waterproof and water-repellent functions.
