Have I bought this belt to avoid landing grade during the summertime on dry land. I opted for the belt because it provides with 4 bottles of 300 ml liquid enough to even longer runs> 20km survive in summer temperatures. The belt as well as the bottles are exceptionally manufactured, processed by the elastic belt in the belt sits very comfortable and really close to the body without however pinch off. In denFlaschen one is the volume really well on the weight is hardly noticeable, the bottles are shaped dense and ergonomically and with light pressure while drinking enough fluid comes out so you do not have to ever suck on the bottle. I'm really pleased. I had ordered my belt just in size "S" but in my waist size of 88/89 and 48/50 suit size was much too tight, the velcro really sat at the far end. Hab then let the exchange briefly at agency WAGS (settlement went excellently by hand) and am perfectly equipped with the size "M".
