Canvas crossbody messenger for work, school and travel. Beautiful dark green
This is a great canvas tote messenger crossbody bag. The canvas material ensures that it’s durable and can hold all the things including iPads/laptops and other school/work related items, making this a great school or commuter bag. It’s the perfect size for that type of bag as well as for traveling when you need extra room to carry necessities. I ordered this mainly because I have plenty of fashionable bags, but my husband likes more plain or “gender-free” bags to carry and this one is perfect for boys, men, girls and women and literally anyone needing a satchel to carry their belongings. The crossbody strap is thick and comfortable and creates a super easy wearing experience, where all your things are close and easy to access. I love the dark green color where even though it’s not black/brown it’s still a “neutral” and matches most everything. Overall it’s a great bag at a great price point that could work for most people needing this style/size. If like me you want to jazz it up a bit, there’s plenty of room to hang bag charmies and chains and the canvas is even easy to hotfix rhinestones to. Would also make a good gift and especially if someone is traveling or moving as I love this size for travel to carry all the extras. I’m very happy with the quality, color, size and comfort.

Spacious, versatile canvas crossbody that hits the sweet spot between purse and messenger bag
I needed something larger than my usual purse but smaller than a messenger bag for days when I need to carry more without going too bulky. This fills that gap perfectly. It could even work as an overnight bag if you travel light. The main compartment is spacious with two interior compartments layered inside it. One is open pocket style and one has a zipper. There are also two open pockets on the outside. The shoulder strap adjusts easily and should work for most people. The zipper pulls have rectangular holes I can clip keys to, and I added a small clip to the main zipper to secure it to the strap hardware. The canvas texture means it isn't wipe-clean, but it should wash easily which matters to me. One unexpected and welcome detail: the desiccant pack inside was scented and made the whole bag smell great right from the start, rather than the usual chemical or dye smell new bags often have. ✅ Highlights • Hits the sweet spot between purse and messenger bag in size • Interior with multiple compartments • Zipper pulls have holes for clipping keys or a security clip • Adjustable strap works for most body types • Scented desiccant pack means no unpleasant new-bag smell ❌ Cons • Main zipper requires two hands to close when fully open • Canvas texture means not wipe-clean This is a well-thought-out but simple bag that works exactly as described. The minor zipper quirk aside, it does everything I needed it to do. -Review of GEMIU "GEMIU Canvas Hobo Crossbody Bag for Women Casual Tote Shoulder Bag Large Messenger Bag for Travel"

A Nice Size Versatile Tote/Bag/Purse
This GEMIU Canvas Hobo Crossbody Bag for Women Casual Tote Shoulder Bag Large Messenger Bag for Travel is a nice versatile tote that can be used as a purse, a work bag, or a travel bag. It is light-weight, made of a medium thick canvas, and can fit a laptop or iPad as well as other items, although it doesn't have the protective cushion for electronics. There are two deep pockets on one outer side, and the other outer side doesn't have pockets, but you can see the stitching from the inner pockets. Inside the bag, there are two pockets on one side; one is zipped and it sits on top of the second open pocket. The main compartment zipper goes beyond the bag so it allows the mouth of the bag to be opened all the way. But with this type of zipper, there is a small opening that remains at the end. The straps are easily adjustable to allow wear as a purse or crossbody. I typically like having smaller purses so I don't have to carry heavy things, but when I go on vacation or visit out of town, it's nice to have a bigger bag to carry things I don't normally carry in my purse (e.g., power bank, umbrella, water bottle, etc.). I can fit my smaller purse into this tote and carry some additional items in it - it's the best of both worlds. The bag does have a slight smell when I first took it out of the plastic package, but it dissipated over time.
