They get very squashy (the Stud Devotes turn into puddles with hardware) and they are pretty darn heavy. I'm 5' 9" and have some muscle in my arms and man, my Almond Stud and Black Stud kill me (and that's just loaded with wallet, keys, cellphone and small planner and sunglass case). I was temporarily tempted by the new colors for the Stud Devote this Fall and then I remembered how heavy the ones I have are...I think I'm suffering enough already for beauty.
The non-stud Devotes are as light or lighter than the Nikki.
