Actually, I did try the Aldi ones before trying to convince my OH they were a good idea.
He only uses them at night at the mo and is OK with the 'Night time safe pants, then pyjamas on' routine now. (Oh I hope I haven't jinxed things by saying that.)
Yup, I suppose the only way to find out is to go for it. They're a wee bit - no pun intended - more expensive than Aldi's but it could save a trek. I'll report back as and when.
