What Our Customers Say
"Best Bag I've Ever Owned"
Borrowed my friend's for a weekend trip. Ordered mine the same day I got back. This bag is insane - fits everything I need, super comfortable, and looks professional. Best $90 I've spent this year.
"Survived 6 Months of Daily Use"
I commute daily and this bag has been through rain, snow, and packed subways. Still looks brand new. The anti-theft pocket saved me once. Worth every penny.
"Replaced My $300 Tumi Bag"
I travel 200+ days a year for work. Ditched my expensive Tumi for this and honestly it works better. More comfortable, better organization, and 1/4 the price.
"My Back Pain is Gone!"
I carry a 15" laptop, tablet, chargers, and more. With my old bag, I'd be hurting after 2 hours. With Cosmo, I forget I'm even wearing it. Game changer.
"Perfect for International Travel"
Took this to 8 countries in 3 months. The TSA-approved design saved me so much time at airports. Fits perfectly as carry-on and holds everything I need.
"Waterproof Claim is Real"
Got caught in a torrential downpour with my laptop inside. Everything stayed completely dry. The waterproof fabric is legit. Can't recommend this enough.
