Sounds like the Swig might be too small for your needs, and it is not downpour-proof.

The Banjo is very well made (as is the Swig) and it is "cavernous." The waterproof liner is easily removed and (apparently) replaceable if it is ever damaged.

Twelve miles is pretty far for backpack commuting but it sounds like you've done it a while and understand the pros and cons. I'm a wimp -- I'd be using panniers at that distance.

Given your height, I agree that you can probably wear the frame pack low-ish on your back and have good sight lines.

Take Care,
