Very interesting to see the set ups posted, thanks for the pics so far.
I look at bike vests from time to time but can't ever come up with a compelling argument over using the fanny pack + water bottles I already have. Maybe one day when they're on sale. I did get a stem bag from local manufacturer
The Spindle ATL. I haven't had time to ride with it yet but it looks well made and should work perfectly for holding clothes/food. Going to have to learn to climb standing with better form as my knees are definitely going to hitting it.
