I'll be traveling next week and next month and realized that rolling suitcases are dreadfully inconvenient in snowy conditions when one relies on public transportation. I'd like a durable bag that is budget airline friendly. In spring weather, rolling suitcases are great, but even the lightweight ones add too much weight, 5-7lbs. I was thinking of getting the medium LeSportSac weekender, but was wondering if anybody knew of cheaper or better alternatives? I own an extra-large weekender and am happy with it, but would rather have something more budget friendly this time, if possible. Checked the usual suspects, but even with a discount, this bag isn't clocking in at less than a hundred.
