Coastal XL - Matte Silver - Deep Blue Polarized is built for bigger heads that make most sunglasses look too small. Coastal is the biggest frame Detour offers, and it typically fits like a glove for anyone who’s had trouble finding shades that look proportionate and feel right from the start.
This is an XL frame size designed to give you more coverage and a more natural look on a larger head shape. The fit is backed up by Detour’s own XL guidance: their XL sunglasses are roughly 8%–10% bigger than their average size, and if sunglasses normally feel tight or don’t cover all of your eye region, you should try XL.
The Deep Blue Polarized lenses are Polarized UV400 Protective for all-day sun protection, and Detour calls out the polarized advantage clearly: polarization helps reduce eye strain, cuts glare, and defines details when looking at reflective surfaces. If bright glare usually forces you to squint or feel fatigued faster, this lens setup is made to keep your view more comfortable.
Comfort also shows up in the hardware. Coastal XL includes comfortable spring hinges, helping the frame feel easier on your head during long wear. And when you’re not wearing them, each pair comes with a free Detour pouch included to keep your sunglasses protected between uses.
