Product Insights
Spitfire's Rethink Square Sunglasses, from an independent London label with a WWII heritage curated by Simons, deliver 100% UV protection (UVA/UVB up to 400nm, meeting ANSI and EN standards) in a durable, lightweight acetate-metal frame that resists heat warping, corrosion, and color chipping. The secure, hypoallergenic fit suits medium-to-large faces without pinching or sliding, while the rigid case and cleaning cloth at CAD 85 elevate the unboxing experience. The tradeoff: styling and durability come at a premium over basic sunglasses.
- Brand heritage
Independent London label with a name inspired by WWII fighters, curated by Simons.
Why this is supported
Catalog verified that Spitfire is not a generic house brand: the label is
an independent eyewear brand based in London, not a house brand or private label of Simons
The story behind the Spitfire label — independent_london_label. Its name references the WWII-era British fighter plane, tying it to an icon of London engineering. Simons’ inclusion of the brand
functions as a soft endorsement for the brand’s design credibility
The story behind the Spitfire label — simons_curation. Additionally, at 85 CAD with a case and cloth, the product
delivers a deliberately elevated perceived value for its price tier

- Durability
Resists heat warping, corrosion, and color chipping.
Why this is supported
Catalog verified that the metal core provides shape memory
providing shape memory that resists warping in high heat (like a parked car) far better than all-acetate frames
Metal-acetate frame comfort and durability — hybrid_frame_engineering. Additionally, the acetate shell prevents corrosion stains
the acetate shell eliminates the skin contact with metal, preventing the greenish corrosion stains common on bare-metal temples
Metal-acetate frame comfort and durability — hybrid_frame_engineering. Finally, the acetate's mass tinting ensures color durability:
Because acetate is tinted throughout its mass rather than painted or coated, the solid black color on the Rethink won't chip, peel, or develop spider-web cracking over time
Metal-acetate frame comfort and durability — color_durability- Comfort
Lightweight, secure, hypoallergenic, and thermally comfortable.
Why this is supported
Catalog verified that
the result is a sunglass that stays in place without pinching or sliding, even on medium-to-large faces
Metal-acetate frame comfort and durability — weight_and_daily_wear_feel. Additionally,
the full-wrap acetate over the metal core on these Spitfires acts as a barrier against nickel and other alloys that frequently trigger skin reactions
Metal-acetate frame comfort and durability — acetate_hypoallergenic_comfort_properties. Finally,
because acetate is less thermally conductive than metal, it won't feel ice-cold against the temples in winter
Metal-acetate frame comfort and durability — acetate_hypoallergenic_comfort_properties- Fit
Fits medium-to-large faces without pinching or sliding, and resists warping.
Why this is supported
The Q&A response from the brand indicates the frame
typically suits medium to large face shapes
What face shapes or head sizes is the one-size frame designed to fit, and does it include adjustable nose pads?, and deep research on the metal-acetate hybrid confirms it
stays in place without pinching or sliding, even on medium-to-large faces
Metal-acetate frame comfort and durability — weight_and_daily_wear_feel. Furthermore, the metal core provides
shape memory that resists warping in high heat (like a parked car) far better than all-acetate frames
Metal-acetate frame comfort and durability — hybrid_frame_engineering, helping the frame maintain its intended fit longer.
- UV protection
100% UV protection blocks UVA and UVB up to 400nm, meeting ANSI Z80.3 and EN ISO 12312-1 standards.
Why this is supported
The 100% UV protection rating on Spitfire sunglasses is verified by the standard definition:
'100% UV protection' designation means these lenses absorb or reflect all ultraviolet light up to 400 nanometers — encompassing both UVA (315-400nm) and UVB (280-315nm)
What 100% UV protection actually means — uv400_standardThis aligns with international safety standards;
A bold '100% UV protection' claim typically aligns with international safety standards like ANSI Z80.3 (U.S.) and EN ISO 12312-1 (Europe), both of which require lenses to block at least 99% of UVB radiation
What 100% UV protection actually means — ansi_z80_3_iso_12312_1Choosing eyewear with verified UV protection also addresses eye health;
Ultraviolet exposure is the primary preventable cause of cataracts and contributes to macular degeneration
What 100% UV protection actually means — cumulative_eye_healthFinally, the UV protection is not compromised by tint darkness;
UV filtration is a chemical property of the lens material and does not depend on how dark the lens appears; the dark tint of these Spitfire sunglasses cuts visible glare but the 100% UV barrier works on invisible rays
What 100% UV protection actually means — tint_independent_filtering- Packaging
Rigid case and cleaning cloth at CAD 85 elevate the unboxing experience.
Why this is supported
Deep research into the packaging-to-price proposition indicates that including a rigid designer case and cleaning cloth at CAD 85 is a deliberate strategy to elevate perceived value for an independent label, building brand loyalty through a premium unboxing experience.
- Brand story
Spitfire: independent London label, Simons-curated, WWII plane name.
Why this is supported
Independent London-based eyewear brand Spitfire is selected by Simons as a curation endorsement, and the naming references the WWII-era British fighter plane, adding a narrative of classic durability. This combination of origin, credibility, and story reinforces the perceived value beyond specifications.
- Frame quality
Hypoallergenic, lightweight acetate-metal frame won't chip, peel, or warp.
Why this is supported
The acetate frame is mass-tinted so color won't chip or peel, and the metal core resists heat warpage and corrosion. The combination yields a lightweight, secure fit without pinching, and acetate's hypoallergenic property prevents nickel contact.
- Frame material
Solid-colored black acetate with a metal core keeps the two-tone frame durable and aligned.
Why this is supported
The acetate is mass-colored, meaning
the solid black color on the Rethink won't chip, peel, or develop spider-web cracking over time
Metal-acetate frame comfort and durability — color_durability. Further, a
metal core — typically a flexible steel or titanium alloy — runs through the acetate temples and frame front, providing shape memory that resists warping in high heat
Metal-acetate frame comfort and durability — hybrid_frame_engineering, which helps preserve the two-tone frame's alignment.
