Traveling in winter is hard on gear, experienced winter campers carry backups for essential gear. Another rule is "keep it simple" the fewer moving parts the less chance it breaks. That's why so many experienced winter travelers pack a spare set of these bindings, very low tech that simply works. easy to tie and put on hands-free. Comes with 2-8' sections.
Works great as your main set or carried as a spare.
