I am making a list of TB accessories I'd like to gift this year. I'd like to get the Snake Charmer for my son. I notice that in the Olive color there is both a Cordura version as well as a Parapack version. Any preferences, pro/cons for each? I did see there was a post about cordura vs parapack in the forums. If anyone who has items in both fabrics could weigh in that would be very helpful. Thanks so much!
