This bag is well built and as near waterproof as possible.
The outside zipper pocket leaks a little but the main compartment was always dry.
We stored our Mountain Hardwear down jackets in it.
It survived over 100 rapids on the Colorado river during a 19 day trip that covered 226 miles.
It''s my go to bag for SUP & canyoneering now. Very comfortable to wear.
Make sure to buckle it properly: to each side of pack as opposed to clipping the ends together.
But 1st squeeze out as much air as possible and get at least 3 rolls of the material.
Love the color and quality of DAKINE gear.
Own many of their products over the last 15 years and have never been disappointed.
