SAETTO Fermo Retainer Strap
SAETTO Fermo Retainer Strap
Product Details
The moment the pace lifts, your frame should stay exactly where you put it. Fermo closes the loop behind your head and keeps your eyewear locked in through every stride and every descent.
DETAILS
- Adjustable strap: a sliding buckle, so the tension is yours and it stays put
- Two lengths: 19.5 cm for a relaxed hold, 17 cm for a tighter race day grip
- Soft grip end tips: slide over the temple arms without scratching them
CARE
Hand wash with mild soap when it needs it and let it air dry before the next session.
Care & Maintenance
Treat the lenses like optics, not plastic. Clean them with the microfiber cloth only: shirts, towels and paper leave micro scratches on mirror coatings. If there is dust or dried sweat on the lens, rinse it first with clean lukewarm water, then wipe. For sunscreen and fingerprints, use one drop of mild soap and rinse.
Keep your pair away from heat: a car dashboard can warp the frame and damage the coatings and the polarizing filter. Between sessions, store it in the pouch or case, and never rest it lens down.
Size & Fit
SAETTO frames are one size with a unisex sport fit: lightweight builds, soft nose pads and grippy temple tips that hold steady once you start sweating. Shield and wrap models hug the face closely to block wind and side light, while the Flow line sits like a classic everyday frame.
Key lens and frame measurements appear in the product details above. If you wear prescription glasses, look for the models with an RX insert, which clips your prescription behind the main lens.
