When I recently upgraded to a double electric after hand pumping for 5 years (yep, five years) it didn't come with a bag, as it's a Lansinoh. I found this bag at Target, way in the back with the camping gear, and it's insulated and everything. Fits my pump and all the accessories along with a cool pack, and I stick my wallet in there too. Under $20! I've had women ask me about my "purse."
