Bottles that can use breast storage bags???

Hello ladies! What bottles do you recommend that you can use with your breastmilk storage bags directly? I tried googling etc, and only seen an obscure brand I've never heard of and playtex. I'm sure there's got to be more out there?? This will be (hopefully) my first time successfully breastfeeding (failed with my other 2). I will be returning to work after 6-8 weeks and will hopefully establish a supply and routine by then. But I would like to make things easy on either husband or sister when I'm at work for feeding baby. And I thought a bottle that can hook right up to the storage bags sounds so convenient! Any thoughts from any breastfeeding/pumping momma vets?!?! I work for the USPS and will have to pump on my routes, so any milk storage coolers and pump recommendations would be awesome too! I have the spectra s2 from my last baby and it's still practically brand new, but if there are any other recommendations, more so ones that I can use in my car (my spectra plugs in I believe so battery powered I think would be ideal), that would be great as well! Thanks for any advice or recommendations at all really! Lol
