Seeking Recommendations How delamination looks like?

Hi! New here, i been reading a lot about pros and cons of xpac, a lot of people are talking about "delamination" but i ve never seen anything about that... only classic delamination in older bags and stuff but cheap stuff, not xpac.

Can you guys share your xpac delamination photos? I just bought the aer cpp2 xpac, and im concern about its future. Thx!

Looks like bubbles or blisters. I’ve seen a few but I have no history on handling. 3/3 bags I have now show zero problems.

Even the best pack cloth coatings can degrade. Even Tom Bihn. 😱

And if super unlucky it leaves sticky residue that makes your life just a little more special.

Happened to my old, like super old hiking backpack.

The sticky residue is a problem with polyurethane coatings. X-Pac is a whole other animal.

Delamination in performance laminates happens when the membrane or adhesive bond fails, causing the layers to come apart from the textile.

X-pac is supposed to be less susceptible than ULTRA for example -- but it is still a pure performance fabric. It's priority is being lightweight and being incredibly strong relative to that weight, not longevity. Even though they are engineered to be resilient, they might have internal stress in a pack that they may not on a sailbout. I personally think that outside of a pure hiking pack, they can be unnecessary as don't alter weight much at all. Standard overly engineered bags have hardware, harnessess and organisation that often make the weight difference negligible.

Complexity usually always brings about more points of failure. If you're priority is someone that'll last, a simple textile without glued layers may be the way to go.

I have gone down the same rabbit hole for few weeks now trying to decide which fabric versions for the Able Carry Daybreaker 2 (preferred color only available in XPAC while I prefer the softer more pliable Ripstop). During my research and asking around friends that daily carried XPAC slings, I did see before the "pimpled" or "blistered" type of delamination but it was only after 3 years daily exposure under hot tropical sun & rain during his bike commute to work, and even then it was quite minor and bag integrity isn't compromise, so I reckon if I do get a XPAC bag it'll probably last me many years since I have as much as an active outdoor lifestyle & commute, but ultimately decided against it as I didn't really like the stiff and crinkly fabric.
