| May 21, 2023 at 11:47 | comment | added | Chris H | @noah That depends on the inner layer. My 3-layer goretex drysuit used a very thin inner layer which didn't do much to stop delamination spreading once it started. And once I cut it up to recycle the fabric it became clear that the inner layer wasn't tightly bonded to the membrane and outer. For the same membrane the type and even number of layers and bonds is variable. I've also had "3-layer" jackets here the innermost layer wasn't bonded to the membrane and shell at all (it's mesh) | |

| May 17, 2023 at 17:32 | comment | added | noah | Not sure that really exists or is possible. You could maybe make a drybag of GoreTex/eVent/Dermizax/etc which is a membrane rather than a laminate. But not sure anyone currently does. S2S makes eVent bottomed bags to allow air out, but they aren't very durable in my experience. Mont Bell makes some GoreTex stuff sacks, but no dry bags. You could DIY one w/ a membrane based fabric, but it probably won't be all that durable, and anyway your seams will need to be sealed by something that will eventually delaminate. | |
| May 17, 2023 at 13:54 | comment | added | Michael Altfield | @noah thanks for the recommendation. On quick check of Hyperlite's website, it does appear that their Dyneema "composite" fabric is, again, waterproofed with a polyethylene lining. My understanding is that it's not a matter of if a lined bag delaminates -- it's a matter of when. Do you have any recommendations on waterproof dry bags that are made from a material that's not a composite made with a waterproof lamination? Something that will never delaminate because it can't? | |

| May 17, 2023 at 7:40 | comment | added | noah | Check out dyneema dry bags from Hyperlite gear or other similar makers. But the fancier you go, the more it costs. If this lasted 4 years of constant use, I'd call that pretty good. Another brand is Watershed drybags, but they aren't lightweight. | |
| May 17, 2023 at 7:39 | comment | added | noah | The MSR bag is probably seeing a lot less abrasion from just having water compared to a drybag with stuff in it. MSR is also designed for durability while S2S for lightness. | |
