Best adult sleeping bag

[PixieandMe]

Looking for the best sleeping bag I can afford for my son who is planning on travelling Europe in a camper van. Needs to be really warm.

Budget £200.

Thank you!

Buerts ones are good. He’d be best with a slightly thinner sleeping bag and a good duvet tbh as a really thick sleeping bag might be too much if he’s in warmer places.

If he is in a campervan I would go for layers, sleeping bag, blanket and a duvet when it really gets cold.

DD has a winter sleeping bag (got it 10 years ago) and stayed in tents around 4degrees but wrapped up in blankets, thermals, socks, hats and gloves.

Agreeing with the layers being the better option, if not lightweight camping where he is carrying everything all day every day.

What temperatures are we talking? Or which countries/seasons?
