Look, several here have given you very good suggestions for EXACTLY what you asked for. Since none have solved your problem, commission a nylon company to make EXACTLY what you want, OR, throw your stuff in your wife’s beach bag? It’s now come down to you know exactly what you want, but it doesn’t exist in reality, so, take the reins and have it built.
Thanks for your suggestion and advice .......but I think I will keep looking . I`m sure the perfect pack for my needs is out there with some further searching .....
Appreciate all of the suggestions thus far .
BTW - I`m not looking for Nylon .
