I bought a new backpacking tent a couple of weeks ago, and being a massive nerd, I overthought it a bit and did some reading about weights and durability of the various materials.
One major headscratcher was the tradeoff between the weight of the flysheet fabric and its life-expectancy, in particular with how quickly UV exposure will cause it to fall apart. Do you want to buy the lightest possible tent for backpacking trips and accept that that's basically all it's for because it won't last long if you also want to use it for regular weekend trips leaving it pitched all day? Or do you buy something a bit more sturdy and compromise on weight?
I ended up wondering whether there'd be a market for tents that went as light as possible but gave you the option of buying a second flysheet made of something cheap, durable and relatively heavy for use on car camping trips and so on.
Would that be economical? Sensible? Or would it be redundant because most people are happy to buy the lightest thing and then get a cheapo Millets job for car camping?
