Key Specifications

Detailed Overview

Design & Style

The FOS 3100/S features a timeless rectangular silhouette that works exceptionally well on round, oval, and heart-shaped faces.2 The gloss black (807) finish gives the sunglasses a sleek, sophisticated look that pairs easily with any wardrobe, from business casual to weekend wear. Subtle branding and metal accents on the temples add a touch of Fossil's signature vintage-inspired charm without being overpowering.3

Comfort & Build

Crafted from injected propionate, the frame is durable yet surprisingly lightweight.4 This ensures the glasses can be worn for extended periods—driving, commuting, or outdoors—without causing fatigue on the nose bridge.5 The 140mm temples are designed to curve gently, providing a secure fit that stays in place during movement.6

Vision & Protection

The lenses are a neutral Grey tint, which is ideal for maintaining true color perception while reducing brightness.7 They offer 100% UV protection, shielding your eyes from harmful UVA and UVB rays during sunny days.8
