I use bathtime ponchos all the time. They're great for snuggling them into after a bath and handy for throwing on the kids when you're at the seaside. Argos has reduced this England football team themed poncho from £9.99 to £1.99.
It isn't available for home delivery, you can only buy and collect from in store. I checked all six of the Argos stores near me, and they all had stock left. Possibly not for long at this price. There's only one review on the site, but I think they missed the point that this is a poncho! The customer writes: "Thought the towel was great apart from down the sides the towels opened up which means it can be a bit cold after getting out of the bath!"
Clearly they've never used a bathtime poncho before, or maybe I'm unique in that all the ones we've used have been like this?
The England Poncho is mostly white in colour, with red and blue motifs. It is made of 100 percent cotton, and can be washed in a machine at 40°C. You can also put it in a tumble dryer on a cool setting for drying. The poncho measures 60cm in length by 120cm in width.
