ULTIMA SYSTEM

Sinch is built on Flexi's Ultima System, a revolutionary concept in ski touring bindings. Click here for a full range of Ultima System features.

Ladder straps and ratchet buckle boot harness

During our ladder strap R&D, we froze multiple materials down to -40c in an industrial test freezer and placed them under severe load; only DuPont Hytrel came out unscathed. Before launching the product we field tested Hytrel on expeditions to both poles and across Greenland, a combined 1300km and 65 days, and it came up trumps.

Flexi Sinch Straps

The boot harness cams into serrated slots in the side walls, no tools required for field adjustments. We recently added a removable pull-loop to enable easy step-in.

BOLSTER KIT

Although Flexi Sinch comes in two widths, optional Bolsters take up any remaining play you may still have between your boots and sidewalls. Easy to install, simply release the straps in the cam slots, insert the bolster and re-engage the straps.
