    Good size but shoulder strap could be better
    The size works well for the gym or short trips. There is plenty of space in the main compartment for clothes, shoes, and gear. The end pockets are helpful for separating smaller items and keeping things organized.The material feels durable and the water-resistant bottom is a nice touch for setting it down on wet surfaces. The only small issue is the shoulder strap padding could be a little better for longer carries, but it works fine for quick trips.Decent gym bag that holds up well and has enough room for most needs.

    This is for the small 38L bag – just the right size to take to the gym!
    I use this for my yoga gear with the bulkiest item being 2 yoga blocks. Plenty of room for towels, yoga mat towel and straps. Just enough pockets (2 on each end, one in front and one inside) so I don’t loose track of where I put what. It fits easily into a locker and seems durable enough to last a while. My only grip (and it is minor) is the zipper pulls do not have holes so I cannot add longer string pulls to them but that is certainly not something that would detract from the functionality or quality of the bag.It does not have a shoe compartment, but I do not want or need one so I appreciate it not taking up room.

    Quality product, very happy after using it for 2 trips.
    Had an older red Adidas bag for 10 years, held up well for dozens of trips, when I wore out and straps broke I wanted a similar replacement. Very happy with this bag, size is big, but not too big. Better pockets than my last one, good quality zippers and bottom in more durable. Would absolutely buy again.. absolutely perfect for a 3 day trip.

    Great size for all my gym gear
    Nice workout bag for me. I go to the gym a few days a week and this bag is big enough to carry my sneakers, gym cloths, towel and ditty bag. Added pockets on each side and a front pocket all zippered give you even more space to put additional stuff in as well.

    Highly recommend
    I got this for my husband for our beach trip. He loves it! The bag is big enough for his week worth of clothes and shoes! This bag is well made and sturdy. This bag is definitely worth buying.

    Great Gym Bag!
    I got the small size and it’s MORE than enough to hold all my stuff for the gym! I can fit all my gym essentials in here easily without worrying about space. I love all the pockets, especially the one with the little holes at the bottom, which I use for all my toiletries when I shower at the gym.Super happy with the quality and style!
