Rooted in effortless style, timeless appeal, and quality craftsmanship, our sunglasses reflect these core principles — a natural extension of our world, the 10DAYS lifestyle.

True to our ethos, unexpectedly simple, we’ve focused on a single model inspired by the 1940s Wayfarer — a classic choice, reimagined through our eyes. 

Translated into 3 key styles:
1. The Essential: A nod to the original, featured in Blue Haze and Leopard.
2. The Iconic: A bolder elevation of the Essential, in cool neutrals: Black, Ecru, and Rope.
3. The Statement: Make an impression with our final design, featuring a unique detachable shade clip, available in Black and Ecru.

Comfort and quality go hand in hand at 10DAYS. Our sunglasses are made in collaboration with a premium, sustainable eyewear manufacturer and crafted from bio-materials that offer the look and feel of traditional  frames whilst reducing carbon and waste. 

Certified for environmental impact and social working conditions, each pair is fully traceable throughout the supply chain.

With 100% UVA/UVB-protected lenses and recyclable frames that can be handed in for reuse, our thoughtful service extends to every detail — from the soft white melee fleece pouch, enhanced toolkit, and sunglasses cords — all made to blend seamlessly into your life.

With a little extra care, it’s easy to keep your glasses in great condition.

Care instructions

Protect your frames:

  • Avoid pushing your glasses onto your head, as it can stretch the frame.
  • Use both hands to remove glasses to preserve the shape.
  • Store glasses in their case when not in use.
  • Periodically check and tighten loose screws to maintain the frame.


Caring for your lenses:

  • Use a cleaning cloth and cleaning spray designed for sunglasses.
  • Avoid using tissues and paper towels, as they can scratch the lenses.

Recyclability & sustainability impact

The sunglasses are made with bio-based and recycled materials that are normally destined for landfills. The frames are crafted using Acetate Renew, produced through a pioneering technology called molecular recycling, with no reduction in material and colour quality. 

This results in a new acetate with a much lower carbon footprint up to a third lower than traditional manufacturing processes. This circular economy innovation diverts plastic from landfills, incinerators, and oceans.

'The frames can be recycled again, maintaining their quality indefinitely. Additionally, the frames are fully removable and can be returned to Yuma Labs to be recycled and reused.'

Production

The sunglasses are produced in a high-quality eyewear factory located in Southeastern China, known for working with sustainable materials. The factory takes care of the land and reduces CO2 with processes like solar energy power and wastewater treatment stations. Our packaging supplier in China specializes in crafting pouches and cleaning cloths with recycled PET, while the sunglasses cases are made with certified sustainably forested wood craft paper.

Frames (85%)
Frames are crafted from Acetate Renew by leading global specialty materials company, Eastman. This is mostly bio-based material made from certified sustainable wood pulp and recycled waste plastics. 

Lenses (7%)
The lenses are 100% UVA/UVB protected, produced by Tritan Renew by Eastman, known as TR18. This material contains 50% recycled and 50% new polyester.

Hinges (4%) and wirecord (4%)
The metal hinges and wirecord are made of 100% maillechort.

Quality control

To ensure that our products meet the highest standards, we conduct quality control checks at every stage of the production process, carried out by an external company called QIMA.

Renowned for their expertise and rigorous standards, QIMA ensures that every aspect of our eyewear product meets top benchmarks, with our sunglasses passing for artwork, colour stability, front bending, screws, pulling, polarization, and function.
