Reddit mentions of evoc Magnetic Tube Clip Black, One Size

This looks to be a functional knockoff of a Salomon adv skin 3 vest. I've used mine for over a year for training runs, and marathons - 50mile ultras. I'm 6'1" and 180lbs and the largest size fits on me but is quite snug. The knockoff brand saves a lot of money, but it's a similar (exact?) design and has held up on me for a year without any issues.

Note, the bottle holders on the front are tight enough that you'll want to refill the front bottles without taking them out of the pockets. Also, you'll want the option with the front bottles so you get something that fits the pouches, and get a bladder/hose elsewhere.

Additionally I got a magnetic clip to attach the hose to the vest - I ran my first 50 milers without that. Tucking the hose between the vest and my body wasn't super comfortable, and came loose on hard downhill descents. Seriously, I love that clip and it's worth the $10-12 that I paid that felt insanely high when I paid it at the time. I got something like https://www.amazon.com/Evoc-901101100-EVOC-Magnetic-Tube/dp/B073FRD8DW/ but bought locally from MEC.
