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.

| Rethink Square Sunglasses: Choose this if you want a square-framed pair with a two-tone look: a thick glossy black upper bar across the bridge, gold metal lower rims, and dark gray lenses with 100% UV protection. The light metal-acetate frame includes adjustable nose pads and fits a 50 mm eye width, 15 mm bridge, and 135 mm temples, so check those measurements against your fit. It comes in one size only, in black, with a rigid case and cleaning cloth included.[1,2] | Cut Forty Square Sunglasses: Choose this if you want a bold, glossy black square-frame sunglass with dark smoke lenses and 100% UVA/UVB protection. The cellulose acetate frame is described as lightweight and comfortable, with sizes of 60 mm eye width, a 15 mm bridge, and 145 mm temples in a one-size fit, and it ships with a hard case and microfiber pouch. It also comes in Brown and Chocolate/Espresso if black isn't your pick; note one commenter characterizes the brand as affordable fashion sunglasses rather than performance eyewear.[3,4,5,6,7] | Cut 108 Tortoiseshell Sunglasses: Choose this if you want a thick, glossy tortoiseshell acetate frame in a rectangular-to-square shape with saturated amber/orange tinted lenses and 100% UV protection, in a light and comfortable build. It comes in one size — 50 millimetre eye width, 15 millimetre bridge, 145 millimetre temples — in the Patterned Brown colorway, with a rigid case and cleaning cloth included. Note that one size may not suit every face, and the listed cellulose acetate material does not specify which component it refers to.[8,9] |
