Those Merino TKMAXX jumpers bobble like a mother****** no matter what machine wash you do them on. Hand only.
I got one from Asos ages ago and the only thing I do with it after washing (usually at 30) is give it a bit of a stretch while it's damp before leaving it to dry and then another pull while it's drying. Stays perfect.
Got this duffle coat from H&M when there was all those online discount codes going a few months a go and I've worn it probably 5 days out of 7 a week it's that nice. If their site was actually working right now I would link to it.
