My sister bought me a honcho. It’s a fleecy poncho with hood and pouch pocket. Great as a poncho, dressing gown, modesty changing “room” and doubles as a blanket. If I have to get out of the van in the night/morning it covers everything. I can leave it loose or tie a belt (or usually an old bit of string) around it. Was so impressed bought one for my hubby. They come in a fleece carry bag, but I turned ours into snoods for around the next and over the head. Super cosy, especially if sitting out and the sun goes down or at a festival. They have load of designs in 4 sizes, large to kids, and for anyone who wants/needs it, camouflage too.
. Prices from £10-£25.
