Stupid question about fabrics

[JohnSnowsTie]

I have two jumpers from the same shop, same style but different fabric compositions.

One of them is 50% acrylic 33% nylon 7% wool 5% angora 5% spandex

The other is 92% cotton and 8% wool.

Which is likely to be the most robust/will wash up the best?

Cotton. Might shrink a tiny bit but won't bobble, will last longer and feel nicer.

Thank you!

Cotton one will fade more, though.

Cotton will last better. but wash at the lowest temp setting, and as it has wool too dry flat on an airer

Thanks all. The cotton one is very pale so fading shouldn't be a prob.

So should 100% cotton vests be washed on low temp?
