Perfect everyday bag for men
Size: One Size Fits Most, Color: (025) Castlerock / Black / Black
It’s lightweight, attractive, and the perfect size for carrying the amount of things you want throughout the day. Can be casual or carried into a fine restaurant. The strap is long enough to wear cross body on a large man. Also, they provide a loop that allows you to fold up the strap and turn it into a short handled bag. Great price for the quality and usefulness.

Great Bag For MEN
Size: One Size Fits Most, Color: (001) Black / / White
This UA bag was about the smallest bag I could find for my needs. I own several bookbags being a student. I wanted something smaller just to throw my wallet, phone, sunglasses, and keys in when I took my dog out 3-4x per day. My Boxer enjoys her walks and keeps her energy low in the house for the most part. This was perfect for exactly my needs. Has several pockets and it goes with any outfit if you're trying to match it up. I didn't want a bag where peeps thought I was carrying a man purse either. This one can go over your neck like an old school camera or carried across your chest like the pew pew is concealed. 🤔.
