A bag for G40 (you have one for G30)
Benefits:
1-Protection for unit
2- Visual aesthetics
3- Safety
4-Lagging would insulate unit, retain heat, and reduce boil/mash times thus benefiting the environment
5- Reduce unit running costs

Was looking for one when I bought it: Surprised none yet existed (?)
Cheers Eric, I can’t see a reason why not + potential for more ££££
