Mongo Versipack

Havent used it a lot yet, but so far Ive got to say I like it. I actually carry a laptop in it although that was not the reason I bought it. I think the real test will be when I travel with it on a long trip. Quality seems really good. Only down side was the price, although I must admit Amazon had it for as cheap as you could find it.

UPDATE - 8/5/19

If I was going to carry the diaper bag of my son I dont want it to be Tiffany blue or something with little bears, little things like that.

These are heavy duty packs which can be a mixed blessing. Durable and nearly indestructible yet heavy. The straps are not padded and can cause skin irritations. The waist strap should be as thick as the shoulder strap, padded and ideally with pockets. The design otherwise is amazing. It will probably outlive me

This bag is amazing! The pockets are well thought out and top quality materials have been used. It fits my full size laptop with a ton of room to spare. Be careful not to over pack though becouse it can get heavy, this is one of the flaws to being a single strap design. I use it as a briefcase, day hikes and pretty much anything you would use a backpack for.

Very cool bag. I take this with me every day. lots of pockets and it is amazingly durable.

Still use this bag everyday.

great

We use this bag as a diaper bag for our 2yr old son. It is perfect! I was tired of replacing cheaper diaper bags, and it was very hard to find a diaper bag that looked good for me (Daddy). This bag is extreamly well made, it should last for years! My son will probably use it for college!
