Carrier for single bun

Hi everyone,
I'm on the hunt for a new carrier for our wee guy Bodie. Our previous carrier is enormous and bulky (and I've got arms like wet spaghetti, so carrying it isn't fun!)
Our vet is a 5 minute walk from our house so looking for something that doesn't weigh a ton. It's literally just for taking him to and from the vet. Any recommendations?

Any standard cat carrier will do. Wilko's, Poundstretcher/ The Hut, The Range, etc should have something. I have a couple of these which are OK for smaller cats or rabbits, have a top opening, and cheap at £11 (plus p&p):
