Review on 🏃 CamelBak Nano Running Hydration Vest - Premium Running Accessories - Breathable 3D Micro Mesh - Dual Adjustable Sternum Straps - Secure Phone Pocket - Ample Fuel and Gear Storage - 34 Ounce by Zane Myers

I have worn camelbak clothing for many years and love them. This vest meets their usual quality standards. The bottles hold firmly in the pockets and are easy to drink and the smaller pockets are perfect for gels etc. And they are very light even with full bottles. I wear medium sized shirts and do weightlifting. medium nano vest and found it a bit tight even after adjusting the straps. So for me I'd probably go a size up, but maybe it's a good fit for those with a more "correct" runner's upper body.
