How do I choose a hiking waterproof backpack

I’ve carried 20kg over for hundreds of kilometers relatively comfortably as I had picked a backpacking Waterproof backpack with a really well designed, well-padded, back and hip belt. In my opinion, the most comfortable hiking pack is going to have a ventilated back, a thick and comfortable hip-belt and the ability to adjust in several places.
In the world of adventure, exploration and functionality, one bag reigns supreme; the Sealock Waterproof Dry Backpack. Backpack was founded to support the adventurous passion possessed everyone. Every detail found in these bags is made to carry the spirit of exploration. 

The Waterproof backpack bag has been with the brand since the beginning, and has gained for them a somewhat steady following, thanks to its high level of built quality and their mission to create the perfect Waterproof backpack!
