Is this thread pattern compatible with MSR water filters?

Great question! The Sea to Summit Watercell X has an industry standard 63mm cap, making it compatible with many water filtration systems, including the MSR Guardian and MSR MiniWorks, which are both able to screw onto the wide-mouth opening of the Watercell.

Can a shower attachment be purchased for the 4 liter?

I think the shower attachment comes with all of them.

can you take a 4/5 full bag of cold water, and add 1/5 of boiling water for a hot shower, or is hot water a no-go?

Hello and thanks for your inquiry. The internal TPU film and RF welds of a Watercell X would withstand boiling water in this use case—the hot water would promptly mix with the cold water. There are restrictions on the use of Watercells and all other soft-sided water containers when storing (very) hot water, which is not recommended.

Does this have a 1000 denier cordura outside like MSR?

Hey There, The Sea to Summit Watercell X doesn't have the 1000 denier Cordura like MSR. Thanks, Jake
