V52® lens technology

Our new proprietary lens technology has an optical clarity far surpassing industry-standard performance lenses. The V52® lenses, made from nylon polyamide, have an ABBE value of 52, meaning less distortion and better vision than polycarbonate or Trivex materials. Our V52® lenses are also 20% lighter than glass or polycarbonate, with excellent impact resistance for added safety and 100% UVA/B protection. The polarization filter leads to reduced glare and enhanced contrasts for even sharper vision.


Detachable headstrap

Whether you're doing outdoor activities such as trail running, kayaking, sailing, or climbing, the headstrap guarantees your sunglasses stay on at all times.


Adjustable temple-ends

The temple-ends contain a metal core that can be adjusted for a better fit. Turning the tips inwards lead to a more secure fit if too big, and can also help to create space if the sunglasses feel too small against the side of the face.


Protective case

The Howlin' come protected in a stylish faux-leather protective case along with a cleaning cloth and a headstrap. They are delivered plastic-free in our VALLON box.
