Tal cual descrito. Muy buen tamaño y cómodo. Tiene 2 formas de sujeción, lo que ayuda a que no se afloje durante la actividad

I do both Mountain and Road cycling, using a Backpack and Rear-Pocketed Shirt, respectively. I intend to use this Waist Pack for Road Cycling, and it appears to be perfect for that, it has about the same amount of aerodynamic drag as a Rear-Pocketed Shirt, and no need to have two Water Bottle Cages. From inspection, I'm pretty sure the waist pack will also work for Mountain Bike, and that will lower my Center of Gravity, which helps stability, plus it is cooler. I have another waist pack, different brand, and cost about the same, and it sucks. The Thule waist pack is probably the best possible waist pack design out there.

A good sports waist pouch. I use during inline skating. Slim and accommodate my needs

Overall i can live with it, the pack serves its purpose for shorter rides as my enduro mtb does not have a water bottle mount and no place in the frame i can mount a aux bag for my tools. the only downside is once bladder is full, it can only accommodate very minimal stuff like small tools, few pieces of energy bars and the phone pocket is too tight, you need to push your phone hard to get in.

Thule makes very nice looking products. The bag itself is practical as a bum bag.. when you add hydration into the mix it's a failure of a product. The tube is not a quick detach which is pretty much standard in hydration packs now. The buckle and Velcro system is nice for when the hydration pack is empty but when this is insufficient to hold the weight properly Velcro loosens after just a step with the buckle being left to carry the weight. Will be returning. Just get a CamelBak

Light, good enough to carry my bike tools and have a full pouch of water to last most of my long rides. Been wanting something like this for a while so glad I got it!

Adequate space for cell phone (Android GalaxyS20 with cover over it), ID, car FOB, few keys. Clips on and extra velcro, adjustable belt, snug, stays in place when jogging. Highly recommend.

La calidad de los materiales parece muy alta, buenos acabados. El pero es que simplemente probándola en casa (dando unos saltos) se baja rápidamente: no es apta para personas de baja estatura (mi caso) porque incluso ciñéndola al máximo no se ajusta (llegas al máximo) y es muy grande.
