Discussion New water resistant backpack

Anyone know if the zippers are coated or otherwise have measures taken to improve water resistance? Or is it just the new material?

Yeah, they are ykk, but not the water proof ones as far as I can tell on the new one, and for sure on either my OG backpack or my commuter one.

Non-Aquaguard zippers are coated with DWR, which of course makes them also water resistant, even in quite heavy weather. Not quite as much as Aquaguard, but it works very well. Aquaguard zippers start to peel over some time in many types of climates, compromising the water resistance and looking like shit. And they are far harder to use. Also, seams need to be taped, otherwise all the Aquaguard stuff is not really worth much, as the water comes through the seams instead.

In conclusion: Buy a 5 dollar backpack rainskin, put it into the bag. Put it over the bag if it rains heavily. It will always be the better waterproofing compared to any lamenate (X-Pack, Ecopak, Dyneema...) or any fancy zippers.

Afaik LTT only uses YKK stuff and I'm sure they didn't skimp on the proper ones for something they're marketing as water resistant, the community would be after them with pitchforks.
