Product Insights
The Slim Rectangular Sunglasses by Le 31, Simons' in-house brand with 50 designers and 60 years of heritage, deliver 100% UV protection in an all-metal frame that bends under impact rather than cracking, outlasting plastic alternatives at $29—this direct-to-consumer house-brand pricing enables metal construction but requires sacrificing polarization, a tradeoff present in the Dino model comparison.
Verified claims
- UV protection
- The "100% UV protection" lenses block virtually all UVA and UVB rays up to 400nm, making them fully sun-safe for daily wear regardless of price.
- Brand credibility
- Le 31 is Simons' in-house brand with 50 designers and heritage since the 1960s.
- Frame
- The metal frame bends rather than cracks under impact, so it is less likely to fail catastrophically than plastic-framed alternatives at this price.
- Quality assurance
- Designed by Simons' 50-person in-house team and backed by over 60 years of Le 31 menswear heritage.
- House brand
- Le 31 is a private label designed exclusively for Simons, so the Slim is a house-brand product rather than a mass-market generic.
- Polarization
- The Slim is not polarized; it provides 100% UV protection only, without polarized glare reduction.
- In-house design
- Le 31 products are developed by 50 in-house technological designers at Simons.
- Model comparison
- The Slim omits polarization entirely, while the Dino model at the same $29 includes polarized lenses for glare reduction.
- Pricing model
- $29 price is a result of Simons' direct-to-consumer house-brand model.
- Hand feel
- The Slim's metal construction gives it a lighter, more formal hand feel than the plastic or hybrid frames in Le 31's budget rectangular lineup.
- Style feedback
- The sole buyer review describes the sunglasses as a fun, eye-catching wear that prompts people to ask where the reviewer got them.
