TYR Big Mesh Mummy Backpack: The Honest Truth About This Bag 2026

I picked up the TYR Big Mesh Mummy Backpack expecting a simple pool bag, and that's mostly what it is. It's a 40-liter mesh backpack sold on Amazon, and I've used it for hauling swim gear, wet towels, and the usual gym clutter.

What surprised me is how much it holds for something this basic. The mesh body lets air move through, so my wet stuff doesn't sit in a puddle all day. But it's not a do-everything bag, and I want to be clear about that before you buy.

What the TYR Big Mesh Mummy Backpack Actually Holds

The main compartment is genuinely roomy. TYR says the updated design adds 20% more capacity than before, and at 40 liters I can fit a towel, goggles, a cap, and a change of clothes without wrestling with the zipper.

There's a small zip pocket up front and a side zipper pocket for goggles or a cap, plus a built-in mesh water bottle pocket. I like having a spot for small items so they don't vanish into the main bag.

The top uses a barrel-lock closure instead of a full zipper. It's quick to open and close, which matters when I'm standing in a locker room with wet hands.

Mesh Venting and Dry Time

The mesh body is the whole point of this bag. Wet towels and damp swimsuits get airflow instead of stewing in a sealed compartment, and the mesh also drains if water pools at the bottom.

One buyer said the mesh material helps towels dry faster and that they don't worry about mold. That matches my experience — it's a bag built around wet gear, not a fashion backpack.

Carry System and Fit

The over-the-shoulder straps are adjustable, and one parent noted the straps adjust enough to fit both a 4-year-old and an 8-year-old. That tells you the fit is flexible rather than precision-tuned.

For adults, the straps are basic webbing. They work fine on a short walk from the car to the pool, but I wouldn't want to carry a fully loaded bag for miles.

Specs at a Glance

Here's what the listing actually confirms. I'm not padding this table with guesses — if the data isn't there, I left it out.

Where It Falls Short

This is a mesh bag, so it offers almost no structure. Set it down empty and it slumps; pack it light and it doesn't stand up on its own. If you want a bag that holds its shape, this isn't it.

The straps are thin and unpadded, which is fine for short carries but not for long ones. And while the bottle pocket works, one reviewer wished the water bottle holder were a little deeper so bottles sat more securely.

There's also no laptop sleeve or padded compartment, so it's a poor fit for commuting with electronics. It's a swim and gym bag first.

What Buyers Keep Saying

The reviews are unusually consistent for a budget bag. People describe it as functional, durable, and good value, and several mention buying a second one.

One reviewer called it perfect for camp days because there's room for everything, from swim gear to extra clothes and a water bottle. Another said it holds all their swim gear plus a towel and is far more efficient than the laundry bag they used before.

A few note the front pocket is good for goggles, ear plugs, and a lock. The recurring theme is that it does one job well without costing much.

Who Should Buy It

If you swim, hit the gym, or pack kids for camp, this bag makes sense. It's cheap, it drains, and it holds more than it looks like it should.

If you need padding, structure, or a laptop compartment, skip it. It's a wet-gear hauler, and it's honest about that.
