Yes. Finally. A minimalist running pack that stays on, doesn't feel like anything, fits well, and does NOT BOUNCE. I've tried all manners of belts and harnesses and some were almost great but they all BOUNCED/slid. I got the sub-45 and it's perfect. I just tried it out on my default 5k. I sweat a lot and no odor on the pack, fast dry. pockets are easy to open. Perfect for phone, wallet, keys, inhaler, tissue with room for more. NO BOUNCE, NO SLIPPAGE.

I am coming from using the flipbelt and can say this is a much better option. I lost the case of my wireless earbuds on a run from the flipbelt (not sure how that even happens) so I'm not making that mistake again. Plus, the flipbelt would ride up and I had to constantly pull it down which was a huge distraction and discomfort while running. The fitly sub45 doesn't move much and sits quite well as a upper torso vest. While I was running, the thought crossed my mind this must be how dogs with those harnesses must feel, very secure. After real world use, I can really appreciate the design and materials. The back has a ventilated cushion so it doesn't get soaked from the sweat off your back. The zippers and pockets feel high quality. My only complaint is the price being a little steep but it's a nice splurge to support me staying active.

Compact, lightweight, and waterproof! It's definitely worth the price compared to other running packs that are double, even triple the price. The fitly bag itself has tagged along on many of my half marathon lengthed runs and has been the perfect companion. It fit like a glove and stuck on my chest well. I tend to put my phone, keys, cards, and some candy, and the pack has kept it all from getting soaked when I encounter unexpected rainfall. It has already lasted me a year and continues to work fine. Good investment.

I had been looking for something like this for a while and this worked perfectly. The size/capacity was great, it fits my ridiculously large Samsung Note 8 with case in the pocket. I fit my wallet and keys in the two front pockets. Over time the elastic bands have lost some elasticity so you have to adjust more often. The fabric itself looks brand new, it seems to be extremely odor resistant. It is somewhat pricey, but I think it's a premium product.

I marked it down slightly only because of sizing issues. I have a chest size of 39 inches, which I don't consider to be large and very especially not extra large, and yet this size states m, l, and xl. Adjusted all the way out it is barely comfortable for me with perhaps an inch of wiggle room. I absolutely love this item because I can't feel that it is on me at all--just what I was looking for. It will not hold a lot of stuff, but I would rather have it just the way it is--not bulky, not bouncy. It appears to be made of high quality.

Great for half marathon! I did not think it would be this comfy, even after all the reviews... but it IS!! The pockets overall are very handy and have lots of possibilities, but they are pretty small, smaller than I anticipated. Still, they hold my keys, ID/Debit card, 4 Gu gels, my phone, and still has a bit of room.

Thank you so much for making the Perfect Mini Running/Hiking and Motocross backpack! My husband and I love going on our KTM 990 Adventure Motorcycles! I am 5'4 and a 38c girl... but my Mini-Backpack fit perfectly! My Husband is 6'3 Medium/Large and he said it was the Best Fit ever! We had space for everything, Our Passport, our driver Licence, my Samsung note 9, the Bikes papers, and our awesome Flask and Nutrition Bar, a Mini first Aid and we were set! Loved the design and how concealed everything was!

This is by far a game changer for me. I'm 5'2 and 120 lbs. Small is a perfect fit. I like to do sprints when I run outside, and I hated the waistband because of the bounce. This has no bounce at all!! Holds everything I need for long or short runs. It's very comfortable even with a sweater on. It's worth the price. The quality and the way it's made is great.
