Form and Function, check and check.
These are great bags for simple and easy bikepacking set ups. I have used the tangle on a few long 50+ mile single track days and it works great for holding my tools, food, and extra water. I will be using the tangle for tools and food and misc. schnadle this summer on the GDMBR, I do not foresee it failing me but if it does I will surely let all of you know how it performed after repeated abuse. I bought the medium and it fits really well on my Large Karate Monkey.
