So, DH order himself a pair of utility trousers (the man LOVES a pocket...) and this strange item arrived with it. There is no reference to what it is on the packaging and there is no mention of it on the invoice of the trousers.
So. It is roughly 50cm diameter and made of the type of waterproof fabric that you might make a foldaway rain jacket from. The ‘outer’ side has a flap with Velcro and the other half of the Velcro is also on the outer, just the opposite side. The inner has two small, shallow zip pockets on opposite sides of the circle. There is a double drawstring all the way around the edge with toggles attached.
Pics included for pondering purposes. Random Savlon tube impulsively included for scale purposes.
WHAT IS THIS THING??
