Im sure, but I am pretty sure these will do for awhile. :cross fingers:
Definitely a great start for 3 seasons. If you want to extend it to colder weather, you might only need to get an IX sock unless its REAL cold. So you have a good set up for awhile. Its the little things afterwards that will creep in... dutch biners, stoves, knives, water systems, etc that makes camp more comfortable.
