Given my rather stringent set of criteria, I've had to do tons of research to find my ideal luggage pieces. Here's what made my list and what are now my faithful travel companions:
Louis Vuitton Montsouris Backpack GM. It's large, durable (can hold up to 200 lbs), frees up my hands completely and doesn't place undue pressure and weight on my shoulders. This one's pretty amazing well.
Louis Vuitton Alize 24 Heures. I usually use this bag to store electronics, food and books. The size and roominess make it an idea carry on piece.
Gucci Duffel Bag. I use this as either a carry on or check in bag depending on need. It folds up which means it can be used as a "I shopped way too much on my trip and need additional luggage to lug everything home" duffel.
Briggs and Riley Transcend 200 Expandable. This is the frequent traveler's brand of choice as all Briggs and Riley luggage come with the most amazing warranty. The Transcend collection is ultra light weight but heavily durable.
Briggs and Riley Baseline. Ballistic nylon. Heavy duty. Lifetime warranty. Enough said.
And of course, what's a trip without a fanny pack? To be perfectly honest, I sometimes rock my pack even when I'm not travelling. I also love this one!
