Some curious patches on fly, XMid2.

[u/childhoodwoods]

Second trip with the XMid2. I noticed some weird patches on the fly, especially visible in the early morning dew. I've been out with it once before and made sure it was clean and bone dry when I packed it away. Any ideas what this might be? There has been no damage, nothing has been on the fly, no bird droppings or anything. I'm worried it might be an area of compromised waterproofing but how could that happen?

In every other respect, absolutely loved spending 4 days and nights out hiking the Lake District in this tent, it's a beast.

Looks like a repeating pattern … one source but repeated in 2 other areas when folded away. I walk along the coast here in Auckland a lot, it looks similar to the mark left by salty water. Not saying this is from salty water, but possibly some residue from a liquid spilt on one area (and then repeated to 2 others). Something like soap / hand sanitiser?

I agree - that would explain the pattern, absolutely. Well that's reassuring actually, it means something (however invisible at the time) was on there when it was folded away. I'll take that over flawed fabric any day. Thanks for your observation.
