All stories6 min readBy The BAPORSSA Team

Weights are the figures on each frame's size chart: one figure per frame, not one per colour. Regular fit is 133–143 mm across; petite is 132 mm or less; wide is 144 mm or more. Our how we measure guide explains the size numbers.

Eight of the 20 weigh 25 g or less. Two things stand out. Small does not mean light: Coco has our narrowest front at 123 mm and is the heaviest frame at 39 g, while Shift is 154 mm across and weighs 20 g. And big lenses do not have to mean a heavy pair: rimless Vanguard has a 65 × 50 mm lens and weighs 22 g.

Backbone, Luma, Onyx and Vanguard: four polarized frames from 20 to 25 g.

What frame weight changes

Nose pressure: the bridge of your nose carries most of a frame's weight, so a lighter pair puts less load on one small area. If a pair leaves marks on your nose, weight is one of the first things to check.
Slipping: more weight at the front gives a frame more reason to drop when you look down. Our guide to glasses sliding down your nose covers the other causes, such as bridge and width.
Long days: a frame can feel fine in the mirror and tiring hours later. Weight matters most if you wear sunglasses all day, for example when travelling.

Low weight does not fix a poor fit, though. A 20 g frame that is too narrow still pinches, so check the front width as well.

Which materials are lightest?

Material or build	Our frames	Weight range
Beta-titanium	Onyx, Shift, Volt	20–24 g
Rimless	Backbone, Vanguard, Edge, Sprint, Air, Contour, Glow, Muse, Arc, Flow	22–30 g
Thin metal	Luma, Aurelia, Halo	25–27.5 g
Acetate	Dune, Noir, Lyra, Coco	30–39 g

Acetate is heavier, but it gives you fuller colour and a bolder line, so it can still be the right choice if you want that look. The sunglasses material guide compares the trade-offs.

Backbone, Air, Contour and Glow: rimless frames from 22 to 28 g, all polarized in these colours.

How to choose a lightweight pair

Find your fit: choose by front width first, using our petite or wide fit frames if regular sizes rarely suit you.
Take the lightest pair in that width: the table below gives the shortcut.
Check the lens: polarization depends on the colour on Arc, Contour, Flow and Lyra.
Check the nose pads: Dune, Noir and Coco have integrated pads; the other 17 frames have adjustable ones, so you can set the height.

FAQ

What are the lightest sunglasses for women?

In our range, Onyx and Shift at 20 g, then Backbone and Vanguard at 22 g, and Edge and Volt at 24 g.

How much should lightweight sunglasses weigh?

There is no official cut-off. Our frames run from 20 g to 39 g, so we treat 25 g or less as the light end; eight of our 20 frames qualify.

Are rimless sunglasses lighter?

Usually, because there is no rim around the lens. Ours weigh 22–30 g, against 30–39 g for our acetate frames. The lightest of all, though, are the beta-titanium Onyx and Shift.

Are titanium sunglasses lighter than acetate?

In our range, yes: beta-titanium frames weigh 20–24 g and acetate frames 30–39 g.

Are lightweight sunglasses polarized?

Weight and polarization are separate. Onyx at 20 g is polarized and Shift at 20 g is not, so check the table for the colour you want. Every BAPORSSA lens is UV400 either way.

Final recommendation

If weight is your first concern, start with Onyx if a regular fit suits you, or Shift or Volt if you need a wider front. Choose Backbone for the lightest pair under $100, and Edge if you need a small frame.
