    Great gym bag
    Love this bag I splurged on it, 35-40 bucks. I would do it again. I got a small and fits me well and in the gym locker, I carry shower stuff a change of clothes and slides in the shoe compartment all fits comfortably. The color Black is my favorite color so it’s perfect, seems like good quality good zippers, lots of rooms and compartments for stuff. Over all very happy

    Stylish but lacks vigor
    This product is great for a duffle bag, it has plenty of space and compartments to put your things. The bag for the most part is pretty durable, however, I use my bag to carry my gym equipment/accessories with me and the divider for the mesh section on the side failed after about 2-3 months of light use (I was only using it to carry my shaker bottle when walking to and from my car and the gym). The other thing to note is there is no plastic or framing for the base of the bag, so after a certain weight, the bag begins to collapse in a similar fashion to a full grocery sac. Other than those issues, I love the bag.

    Ideal for what it is. Thin material, but for the price not a bad purchase. Holds a ton of stuff.
