MATEIN 40L Expandable Travel Backpack — 3-in-1 Convertible, 13K+ Reviews! $39.99 CAD (22% Off)

With 13,771 reviews and a 4.7-star rating, the MATEIN travel backpack ranks #17 in Casual Daypacks and moves 200+ units monthly—it is one of the most popular carry-on backpacks on Amazon Canada. The expandable design reaches 40L when unzipped, yet the standard 19×13×8-inch dimensions meet Canadian airline carry-on requirements, fitting into overhead bins without issue.

The standout feature is the 3-in-1 convertible design: shoulder straps tuck completely into a zippered back panel, transforming the bag from a backpack into a duffel or briefcase-style carry. Four external compression straps keep contents from shifting while reducing stress on the zippers. The adjustable sternum strap distributes weight across your chest for more comfortable long-haul carrying.

Made from lightweight water-resistant polyester with lockable zipper heads, the bag weighs just 0.89 kg. A luggage pass-through strap on the back lets you slide it over a suitcase handle. Note: there is no dedicated laptop compartment or water bottle pocket—this bag is purpose-built for travel rather than daily commuting.

Originally $50.99, now $39.99 CAD after a 22% discount, backed by a lifetime warranty. At this price with this volume of positive feedback, it is a strong contender for anyone looking for an affordable, no-fuss carry-on travel pack.
