“You want a valve on your drybag”

“Great dry bag. I own a few, with this 5l being the smallest (and its pretty small, use it for food and small gear). Especially on the larger bags (that you'd use for clothes) the release valve is key. It allows you to compress everything and fit more in the bag. I use this bag for racing and although its durable if I was going to use if for family trips I'd go for the heavier weight bag.”
