Product Insights
The Cut 108 Tortoiseshell Sunglasses from Spitfire deliver a cellulose acetate frame and optical-grade nylon lenses for 85 CAD, 35% less than Warby Parker's entry acetate, with a rigid case and cleaning cloth that add estimated $15–25 in separable value. The lenses provide 100% UV protection and anti-reflective coating to reduce glare and eye strain, but are not polarized—a tradeoff at this price. The acetate frame is durable with integrated, non-adjustable nose pads, and the fit is recommended for narrow faces (120–129 mm), making them unsuitable for wider faces. The anti-reflective coating requires care: only the included cloth is safe for cleaning.
- Materials
Cellulose acetate frame and optical-grade nylon lenses at 85 CAD, 35% below Warby Parker's entry acetate.
Why this is supported
Acetate is a material that requires hand-polishing and offers superior depth of color and natural feel compared to petroleum-based plastics — its use here at 85 CAD is a differentiator, as acetate is more typical of frames priced north of $100
How the price compares to similar acetate sunglasses — acetate_frame_materialinherently impact-resistant and lighter than polycarbonate or glass
How the price compares to similar acetate sunglasses — nylon_lens_constructionWarby Parker's entry-level acetate sunglasses retail for $95 USD (~$130 CAD) and include a hard case and anti-reflective coating; the Spitfire Cut 108 at 85 CAD comes in about 35% below that DTC benchmark while matching the core material and accessory offering

- Accessories
Included rigid case and cleaning cloth add $15–25 in value, uncommon at this price point.
Why this is supported
provides crush protection for the acetate frame and is a tangible value-add typically priced at $15–25 when purchased separately
How the price compares to similar acetate sunglasses — rigid_designer_case_inclusiondelivers a more premium unboxing experience than typical sub-$100 sunglasses, which often ship with only a pouch or folded cardboard
What you get: case and cloth quality — presentation_and_value_at_85_cad.
- Polarization
100% UV protection and anti-reflective, but not polarized — a trade-off at 85 CAD.
Why this is supported
The lenses are not polarized; they offer 100% UV protection with anti-reflective coating, but polarization is not mentioned in the product specifications
Are the lenses polarized in addition to having UV protection?.
- Lens material
Optical-grade nylon lenses are impact-resistant and lighter than polycarbonate, reducing fatigue for extended wear.
Why this is supported
The lenses are made of nylon (optical-grade nylon)
What material are the lenses made of—glass, polycarbonate, or CR-39?, and the material is

How the price compares to similar acetate sunglasses — nylon_lens_construction, making for a comfortable, all-day-wear experience.
- Anti-reflective coating
Anti-reflective coating reduces glare and eye strain; clean only with included cloth to prevent scratches.
Why this is supported
The lenses
offer 100% UV protection with anti-reflective coating
Are the lenses polarized in addition to having UV protection?, which reduces glare and eye strain. However, the coating is sensitive:
using shirt material or paper products would risk permanently marring the lens surface
What you get: case and cloth quality — ar_safe_cleaning_cloth, so the included cloth is essential for care.
- Fit
Recommended for narrow faces (120–129 mm); too narrow for wider faces.
Why this is supported
The product Q&A states:
For narrow faces (face width 120–129 mm), a lens width of 50 mm or smaller is recommended [3].
How does the frame width (50 mm eye size) fit on wider or narrower faces?It also warns that
Wider faces may find the frame too narrow.
How does the frame width (50 mm eye size) fit on wider or narrower faces?This indicates a fit threshold around a face width of 130 mm.
- Nose pads
Nose pads integrated into acetate frame and not adjustable.
Why this is supported
The Q&A states:
The nose pads are integrated into the acetate frame and are not adjustable.
Are the nose pads adjustable, or are they integrated into the acetate frame?This means the bridge fit is fixed; typical for acetate frames but may cause slipping or pressure points for some bridge types.
- Case and cloth
Rigid case and AR-safe cloth add an estimated $15–25 in separable value.
Why this is supported
The rigid case provides crush protection essential for the acetate frame.
The case is a hard-shell design, providing crush resistance that soft pouches cannot — critical for acetate frames that can crack under pressure when packed in a suitcase or beach bag
What you get: case and cloth quality — rigid_designer_case_as_travel_protectionThe included cleaning cloth is designed for the anti-reflective coated nylon lenses.
The included cloth is suited for the anti-reflective coated nylon lenses, allowing removal of smudges without introducing micro-scratches that would degrade the coating over time
What you get: case and cloth quality — ar_safe_cleaning_clothTogether, they deliver a premium unboxing experience typical sunglasses lack.
the combination of a rigid designer case and cleaning cloth delivers a more premium unboxing experience than typical sub-$100 sunglasses, which often ship with only a pouch or folded cardboard
What you get: case and cloth quality — presentation_and_value_at_85_cadThe case separately is a tangible value-add, reducing net frame cost.
a tangible value-add typically priced at $15–25 when purchased separately
How the price compares to similar acetate sunglasses — rigid_designer_case_inclusion- Durability
Acetate frame is durable for typical use with included hard case and integrated nose pads.
Why this is supported
The frame's durability is reinforced by the included rigid case that provides essential crush protection.
The included rigid case provides crush protection for the acetate frame and is a tangible value-add typically priced at $15–25 when purchased separately; many competitors in this segment ship with soft pouches or no case at all, making the net investment in the frame itself effectively lower.
How the price compares to similar acetate sunglasses — rigid_designer_case_inclusionIntegrated nose pads eliminate a common mechanical failure point.
The nose pads are integrated into the acetate frame and are not adjustable. This is typical for acetate sunglasses without separate nose pad arms.
Are the nose pads adjustable, or are they integrated into the acetate frame?While prolonged sun exposure can potentially cause brittleness, normal use and storage in the case prevent this from being an issue.
Acetate frames are generally durable and lightweight, but like all cellulose acetate, prolonged exposure to intense sunlight can potentially cause brittleness over many years. With normal use and storage in the included case, this is unlikely to be an issue, and the material is considered a high-quality choice for sunglasses.
How durable is the acetate frame, and does it become brittle over time with sun exposure?- Value
At $85 CAD, offers acetate frame quality typical of $100+ frames, 35% below Warby Parker.
Why this is supported
The hand-polished acetate frame offers material quality typical of frames over $100, making the $85 CAD price a strong value.
Acetate is a material that requires hand-polishing and offers superior depth of color and natural feel compared to petroleum-based plastics — its use here at 85 CAD is a differentiator, as acetate is more typical of frames priced north of $100, signaling a focus on tactile quality over margin.
How the price compares to similar acetate sunglasses — acetate_frame_materialThis value is reinforced by a direct price comparison with Warby Parker.
