If you ride at the edge of two sizes, size down for a responsive, locked-in feel or up for a more relaxed fit. Boots should sit snug inside the binding with no heel lift.
Component Breakdown
S8 Duraflex Baseplate
One of Union's lightest baseplates ever — the S8 Duraflex baseplate helps reduce the Rosa's total weight by over 10 grams while maintaining all-mountain durability. Featherweight construction for women who want a binding that disappears underfoot.
CP3 Duraflex Highback
Inspired by the original Contact Pro highback, the CP3 Duraflex highback delivers a lightweight, durable design with a soft, freestyle-focused flex profile. The CP3 is the perfect women's-tuned highback for playful, surfy riding — soft enough for presses and butter, supportive enough for charging.
ExoFrame 2.0 Ankle Strap
ExoFrame 2.0 ankle straps provide a secure and locked-in ride feel. Lightweight, super durable, and a team and shop favorite — Union's lightest ExoFrame option for the weight-conscious rider.
TS 1.0 UltraGrip Toe Strap
Multi-positional options and thermoplastic anti-slip material keep you locked in and on point. The TS 1.0 UltraGrip toe strap is compatible with all boot shapes on the market and Union's lightest TS option for the Rosa's weight-focused design.
Magnesium S1 Ratchets
The all-new Magnesium S1 ratchets are Union's answer to the elements. A fully integrated spring protected from the harsh outside provides you with fast, fail-free ladder action run after run. Magnesium is lighter than aluminum for the Rosa's featherweight design.
Extruded 3D Aluminum Heelcup
Designed for optimum heel hold and minimization of drag. Backed by Union's lifetime warranty — the core of every Rosa is built to last.
Duraflex + Thermoformed EVA Footbed
Duraflex base with thermoformed EVA cushioning — lightweight, supportive, and tuned for the Rosa's playful feel. Your feet and knees will thank you after a long day of progression.
Thermoformed EVA Bushing
Provides additional dampening and shock absorption between the baseplate and the board. Smooths out the ride on hardpack and chatter without dulling the board feel.
Grade 8.8 Steel Hardware
The strongest steel available on the market. Comes pre-installed so you can mount and ride without a hardware run to the shop.
