I'm considering a new "personal item" purchase. I'd like something near the top of the allowable air canada size (17x13x6). I'd like it to function as my briefcase and look at least somewhat dressy. I'd like it to work with a rolling carry-on suitcase (strap or clip to it in some way).
I'm considering the ID and the Zephyr. I'm confused about their relative specs:
ID 15.75 x 12 x 5.5 = 1275 in3: Zephyr 16.7 x 12.4 x 6.3 = 1070 in3. How is the Zephyr larger in every dimension but smaller in total volume? Can anyone explain to me?
My impressions: ID: like the larger volume. like the waist strap (may use to strap to a roller suitcase). Zephyr: like the roller handle sleeve. Like the look.
If the Zephyr had larger volume than the ID (given its larger dimensions) and had a waist strap I'd be all over it. As it is: I'm torn.
