Carter ★★★★★ Oct 21, 2026

These are exactly the right shape for the Sideral’s buckle channel, so the fit was immediate and snug. The loop feels sturdy enough to handle a full season of cranking on it, and swapping the old one took maybe two minutes.

Stella E. ★★★★★ Oct 20, 2026

Installed these on my Siderals and they cinch down tighter than the factory straps ever did. The buckle holds securely even after a full day of hard carving.

The loop attachment points feel much more secure than my old Velcro strap. Finally no more fumbling to adjust tension on the mountain.
