How waterproof should a hiking backpack be for heavy rain?

For alpine-level storms, a 5000mm hydrostatic head rating with welded seams is recommended. PU-coated fabrics under 2000mm are insufficient for extended heavy rain.

Are waterproof hiking bags truly waterproof for submersion?

Most hiking bags are not made for submersion. Only dry bag-style backpacks with TPU lamination and roll-top closures can resist brief immersion.

Is TPU better than PU for waterproof backpacks?

TPU offers higher abrasion resistance, better waterproof retention, weldable seam construction, and greater compliance with PFAS-free standards. PU is less durable in wet climates.

Do waterproof zippers make a big difference?

Yes. Waterproof zippers such as YKK AquaGuard reduce water ingress significantly, especially under directional rain or river spray.

Why does my waterproof backpack still get wet inside?

Water often enters through seam holes, non-waterproof zippers, or worn fabric coatings. Waterproofing depends on all components working together.
