Review on 🏃 Nathan Men’s VaporKrar 4L 2.0 Hydration Pack/Running Vest - 4L Capacity with Twin 20 oz Soft flasks, Hydration Backpack Ideal for Running, Marathon, Hiking, Cycling by Eric Nallamothu

Update: L back to size XL. I have to say if you are an adult this vest is not for you. When the 11-year-old gets home today we can try it on, but I think Nathan may have forgotten that the vast majority of ultramarathoners aren't 5ft 2in, 110 tall. It's sad because the fabric and the feel make me think. It would be comfortable and functional if only it fit. But the reality is that it's not good for an endurance athlete if it's so tight you can't breathe in it. Which really makes me shake my head, why not. Just make the straps an inch or two longer? Is there enough room for that. And why are both straps the same length (every other vest has a longer bottom strap). One last thing. Could you at least stretch the straps? a little bit? Even my $25 Aonijie vests have elastic chest straps! Very disappointing company like Nathan. Asian size. This is "Asian youth size"! Check the fit chart as the "chest strap" appears to be at least 4 inches shorter. even connect. I would say big, at least small - maybe super small. I'll try the XL and see if it works, but it seems VERY unlikely that this vest will work for anyone of any size (I'm 6ft, 210).
