YY Vertical Plasfun Evo Belay Glasses - Orange Edition Review (2026)

What these glasses are for

Belay glasses use an angled prism so a belayer can look straight ahead instead of tilting their head back to watch a climber overhead. The Plasfun Evo is YY Vertical's step-up model above its entry-level Plasfun First, built around extended BK7 glass prisms that the manufacturer says widen the field of view compared with smaller prism designs. The frame is polycarbonate with a soft-touch coating, which keeps the glasses light on the face during a long day of top-roping or route setting. They are designed to be worn over prescription glasses as well as sunglasses, which matters for anyone who already wears corrective lenses at the crag or in the gym. This orange edition is the same optical platform as the black and blue versions, just in a color that is easier to spot on a rope bag or gym floor.

Fit, comfort and everyday use

Because the Evo sits on the face rather than requiring the belayer to look up, it is aimed at people who spend real time on belay, such as gym staff, coaches, route setters and climbers who partner up often. The soft-touch coated polycarbonate frame is built to be comfortable through extended sessions without pinching or fogging as much as a rigid metal frame might. YY Vertical states the glasses can be worn over most prescription eyewear, which is a common complaint with cheaper prism glasses that only fit a narrow range of face shapes. The orange colorway is purely cosmetic, so comfort and optical performance should match the black and blue editions. Climbers who already own the cheaper Plasfun First and found the fit awkward may notice the Evo's more refined frame shape is easier to keep in place.

What comes in the box

YY Vertical ships the Plasfun Evo with a hard case that opens with one hand and includes an integrated carabiner, so the glasses can clip straight onto a harness gear loop between routes. The package also includes a safety cord, a microfiber cleaning cloth, a small screwdriver, two spare screws and additional nose pads, which is a fairly complete accessory set for this price range. The spare hardware is a practical touch since prism glasses see rough handling when they get tossed in a pack or clipped near hardware. The case protects the lenses from scratches when not in use, and the cloth is meant for cleaning the prism surfaces rather than general wiping, since abrasive cloths can mark optical coatings over time.

Durability and care

The frame is plastic rather than the aluminum or magnesium alloys used on some premium belay glasses, which keeps weight and cost down but means the Evo is more likely to show wear if dropped repeatedly on rock or concrete. YY Vertical backs the Plasfun Evo with a two-year warranty against manufacturing defects, which is a reasonable term for an optical accessory in this price bracket. Keeping the glasses in the included hard case when not clipped to a harness will help protect the prisms and hinges, since loose storage in a chalk bag or pack bottom is the most common way belay glasses get scratched or bent. Regular use of the microfiber cloth rather than a shirt or bandana will also keep the prism surfaces clear.

Who should buy the orange edition

Choose the orange Plasfun Evo if you like the Evo's refined frame and optics but want a color that stands out in a shared gear bin, a gym lost and found, or a crag pack where black gear tends to blend together. It is best suited to belayers who want a noticeably wider prism view than a basic model like the Plasfun First offers, without stepping up to a metal-framed flagship pair. Climbers who mostly belay occasionally and do not mind looking up may not get enough use out of any prism glasses to justify the purchase. For gyms outfitting staff or route setters, the bright color also makes it easier to track which pair belongs to which station.
