This is a SALOMON trail running backpack vest. It's lightweight and breathable, and comes with a hydration pack and bottles. I've only used it once, but I felt it was a bit too serious for me, so I'm selling it. It's a good size for women. - Brand: SALOMON - Color: Orange/Gray - Features: Hydration pack - Accessories: 2 bottles - Size: M (Suitable for women) Thank you for looking.
