Mier Large Duffel Backpack Sports Gym Bag with Shoe Compartment – 45L/60L/90L Travel Duffle with Weather-Protected Zippers

Switching between backpack and duffel mode is seamless and the shoe compartment keeps my cleats away from everything else. Zippers feel heavy-duty. Took the 60L on a weekend trip and it swallowed everything.

The 90L is genuinely huge — fit a week of camping gear plus a sleeping bag. Straps are padded well even when heavy. Only minor gripe is it's a bit bulky to store when not in use.

Bought the 45L as a carry-on for a two-week trip and it held more than I expected. Comfortable as a backpack through the airport, easy to convert for overhead bins.

Overall solid construction and the shoe compartment is a nice touch, but one of the backpack strap clips popped off under a heavy load. Mier customer service sent a replacement quickly, so credit there.

I go straight from work to CrossFit five days a week and this bag has handled it all — shoes, sweaty clothes, shaker bottle, laptop, lunch. The weather-protected zippers glided smoothly even after my bag sat in the rain on a bike rack. The base fabric shows no wear despite being dragged across gym floors constantly. My old Nike bag fell apart in six months; this one still looks new. Zero regrets.

60L fits my gear, my daughter's swim stuff, and then some. Shoe compartment fits my husband's size 13s, which is rare. Wouldn't mind more interior pockets.

Honestly didn't expect much for thirty bucks. The stitching is reinforced, the zippers are smooth, and the convertible design actually works instead of being a gimmick. Great buy.

Used the 45L for multiple weekend trips. Fits in overhead bins, comfortable to carry, and the shoe pocket doubles as a laundry bag on the way home. The side handles are slightly thin but fine so far.

My fault for ordering the 90L, but even the layout makes it awkward for just gym clothes. Material seems fine, just know what size you actually need before buying.

Carries two kids' worth of soccer gear plus my own gym kit and never complains. Converts to backpack mode so my hands stay free for the cooler and the kids. After a full season it still looks and works like new. Best thirty dollars I've spent on gear in a while.
