Good to know

The vest is unisex and fits a wide range of body types thanks to the adjustable sternum strap. It is compatible with Salomon's 1.5L hydration bladder if you prefer a reservoir over flasks. The 4-liter capacity is enough for a light jacket, food, and essentials, but not for bulky gear. Machine washable for easy care.
