I never had problem BEFORE I used them, so maybe its partially my fault because I ASSUMED they would protect better than my other method??
Portage packs get tossed around pretty good, and if nothing else, I should of put the carrier in a zip lock, but I just had a small bungee around it and when a egg/eggs broke, i had a nice mess >:( >:(
i don't take eggs anymore, but the posts had some good ideas, so maybe I'll try it sometime using one of the inventive ways mentioned ;D ;D
