    External shoe storage is a game changer

    After reading a ton of reviews across many brands, it became clear that the idea of a dedicated shoe compartment is but in actuality it sucks because once your bag is fully loaded it’s almost impossible stuff the shoes in. The external shoe storage allows me store shoes (and boots) comfortably without creating creases which is a huge bonus when throwing leather boots or dress shoes in the compartment. If you are always packing shoes in your bag like me, then don’t be concerned with only having 26L. This bag feels like it can store more than my previous 35L OGIO. I think mostly due to the external shoe compartment combined with the more vertical shape of the bag. The only small issue I have with this bag is that I wish the top external storage was pocket was a bit bigger so that I could store more office related materials.

    Best backpack in the market!

    I bought this product around a month ago and I am extremely happy with how each feature, pocket and/compartment were well-thought. Having the shoes stored outside also facilitate a lot during my day to day activities which start in the morning at the gym and then heading to my office work day. Really recommended

    Best Upgrade

    Needed a new gym bag because I started walking to work more often and my normal duffle gym bag became irritating to carry around. The outer shoe compartment is by far my favorite feature, now my bag won’t smell like my work boots.

    So far I can fit my uniform, towel, two 5.80oz containers and 2 changes of clothes along with toiletries. I still feel I can fit more but I don’t need to. I think I’ll upgrade later down the road but the bag is really durable so it may be some time. Overall, my best gym purchase yet!

    Wish it was little bigger and a better handle to carry

    The bag is great looking, and they use solid hardware. My biggest problem is the handle extremely uncomfortable. And I rally wish the top of the bag was not slanted and just went straight.

PLUS Backpack — Gym Backpack with External Shoe Storage and Flat-Packing Access

The PLUS Backpack takes gym bag functionality and reimagines it for athletes who prefer backpacks. With its external ventilated shoe compartment, it solves one of the biggest issues in gym carry: keeping dirty shoes away from clean gear. Originally designed for CrossFit, it’s the backpack built for lifters and athletes who need organized space and uncompromising durability.

Why the External Shoe Compartment Matters

Most gym backpacks force you to stuff your shoes in with the rest of your gear, leaving everything smelling like your sneakers. The PLUS Backpack fixes that with a dedicated external shoe compartment:

  • Odor Control: Shoes stay separate from clean clothes and gear.
  • Extra Space: Keeps the main compartment clear for larger items.
  • Convenient Access: Slide shoes in and out without digging through your bag.

Flat-Packing Clamshell Opening

One of the biggest advantages of the PLUS Backpack is its flat-packing clamshell design. Instead of digging from the top like a standard backpack, the bag unzips fully and opens like a suitcase, making it incredibly easy to load, organize, and access your gear.

  • Pack Flat: Lay the bag open and place items exactly where you want them.
  • Quick Visibility: See your entire setup at a glance — no more lost gear at the bottom.
  • Travel Ready: Works like a compact gym suitcase, built for athletes on the move.

Combined with the external shoe storage, this clamshell design makes the PLUS Backpack one of the most functional gym backpacks you’ll ever carry.

What Fits Inside

The PLUS Backpack is compact yet suprisingly spacious. Here’s what you can pack:

  • 1 pair of sneakers or lifters (external shoe compartment)
  • Change of gym clothes
  • Towel
  • Shaker or water bottle (side pockets)
  • Knee sleeves, wrist wraps, or grips
  • Chalk container
  • Headphones and small tech
  • Wallet, phone, and keys (internal valuables pocket)
  • Snacks or post-training supplements
