Hello!

I have been commuting by bike to work this year but have been away from home in a much warmer climate (California vs upstate New York).

I am moving back to Rochester to continue my studies and am planning on tackling a ~15 mile one way commute through the rain, snow, and sleet. Daily, I will need to carry a laptop, charger, lunch, change of clothes, and gear for all the lovely weather I will certainly encounter

For a bag set-up, I was thinking of getting a waterproof pannier for my gear, then use my grocery pannier to hold a normal backpack inside a dry-bag (i don't need a mega $150 waterproof backpack for everyday use) so I will not have to carry the backpack on my back while riding.

Any suggestions or advice on the topic would be very much appreciated!
