The belt bag that finally fits your body.
No extenders. No digging. No “make it work” hacks. This belt bag was built from the start for plus‑size bodies
Tested on a size 22 fit model and adjustable up to 90 inches, it’s made to fit numerical sizes 14–40 with ease. Wear it high on your waist, low on your hips, crossbody, or across your chest — the strap is long enough to give you options, not limitations.
Three zipper compartments keep your essentials organized, the hidden pocket keeps your valuables discreet, and the water‑resistant canvas/nylon keeps up with your everyday life.
This is what a belt bag feels like when it’s actually designed for you.

Great product, amazing company!
It just feels good! Fits perfect, and the zippers are STRONG.
This bag is made really well, I'm the gal who stuffs it full, sometimes with messy crap from my art projects...and I can wash it out easy! It fits everything. I'm glad I have the black so it hides any mess I run into, but am I brave enough to get a second in another color?!
OOOO, do I want one that is multi color? Jewel tones? With threads that stand out and don't match?
Yes, yes I do!
I’ve only had this bag for a couple weeks but it’s my new favorite! It’s the perfect size for concerts and I’m definitely going to use it at conventions since it actually fits around my wrist without squeezing me to death. Fits perfectly on my wrist/hips and as a crossbody. Also am very happy to support a small business that’s based out of Minneapolis, especially right now in 2026.
Thank you so much, Piper! I am grateful for your support & happy you love your waist bag.
Thank you!

It feels like everyone is wearing waist bags these days and as a tall (6 ft 1!), plus size (4x) person I thought it’d be nearly impossible to find a waist bag that fit me. Then I went to Philly Fatcon and saw the Fitso Belt Bag as a raffle item and was so excited to see it! I entered the raffle thinking if I don’t win, I’m going to go home and buy one — and I ended up winning the raffle! It’s so cute, it has so many pockets, and it’s so empowering! I’m going to get a lot of wear out of this, my first belt bag! Highly recommend!!!!!
Brianna, thank you so much for sharing your great experience with our belt bag. This is exactly why we designed it & I am so glad you find value in our belt bag.
