We break down what drove each score so you can weigh trade-offs.
Quality Analysis 70/100
These swim shorts are crafted from 100% polyester seersucker, a material known for its quick-drying properties and resistance to wrinkles, making it a practical choice for swimwear. The inclusion of a polyamide/Spandex lining further enhances comfort and shape retention.
Comfort Assessment 90/100
These swim shorts offer a comfortable experience thanks to their lightweight seersucker fabric and the added flexibility of 8% Spandex in the lining, ensuring ease of movement. The built-in mesh briefs also contribute to a secure and comfortable fit.
Sustainability Impact 60/100
This garment lacks specific sustainability clues, such as certified materials or eco-friendly production methods. The primary fabric is 100% polyester, a conventional synthetic, which impacts the default sustainability score.
