Here's a link to a LIFESAVER posted in the Prodigy forum. I own one of these and it turns out the SB also fits in.
You can also keep the 510 atty attached if you don't zip it all the way closed (leaving only about a 3mm opening)
It does require a tight fit the first few times till it stretches out, but works fantastic. I can carry 30ml, 15ml, and 10ml bottles (multiples), extra batts of all sizes, a backup e-cig and extra attys in a small convenient case!
