Most river trips are not limited to just being on the river. Sure, on some trips there is plenty of time to make the transition from being on the river to exploring the land along the river. But sometimes you want to hit the ground running right as you’re pulling your boat onto the shore. For both of these scenarios OR’s DryComp Ridge Sack fits the bill. I have a nice little Mammut backpack that I love and use for the majority of my terrestrial trips. For it to come on my river trips it needs to be stored in a dry bag taking up valuable waterproof room. Enter the DryComp Ridge Sack.
