We prefer carryon whenever possible; and for the past several years, Ms. Gecko has been using one of the better 22" roller boards, while I've been using a duffel bag with shoulder strap. As expected, roller boards don't always "cooperate," especially on stairs and when going into an overhead compartment, and carrying a heavy bag over one shoulder gets pretty tiring when trekking through airports and hotels. We found a better way thanks to the Etech2.0 Weekender Convertibles at www.ebags.com/search?term=eTech+2.0+Weekender+Convertible&pl=hdr_srch_sf_l1 The descriptions, photos, and many positive reviews, and of course the price, prompted us to order. However, being unsure what size to get, we ordered the full and junior versions in the same color (plum) with the intent of returning one. (She was still rather content with her roller board.) Delivery only took a couple days, though we were somewhat taken aback by the small package that arrived not much larger than an express document folder. Yep – looks are deceiving. Upon unpacking, we were immediately impressed how the compressed bags expanded and how the quality was exactly as advertised. We did a trial packing with the usual contents and were amazed how everything went into the bag – both bags - with plenty of space left over. To make a long story short, we kept both bags, the smaller for her and the larger for me, and took them on an eight night trip to Vegas shortly thereafter. What a difference, though it took a few days remembering what we stashed in the various compartments. Is it possible to be in love with piece of luggage? It's not often we purchase a product – any product – that is actually as good or better than expected. About the only semi complaint (if you can call it a complaint) were the dangling backpack straps. Tying them up kept them off the floor, but a small piece of Velcro should do the job on future trips. We've submitted a similar review on ebag's website to join the other overwhelmingly positive reviews. No, we don't get a commission - just sharing a positive experience.
