The one that’s always packed first.
The Castaway-Sand
The best shirts aren't the ones with the most features. They're the ones you reach for every time you walk out the door.
The Castaway was built around a simple idea: make a shirt the way it's supposed to be made. Clean lines. Premium materials. Thoughtful details. Nothing extra to weigh it down.
Constructed from a lightweight blend of 88% nylon and 12% spandex, the Castaway delivers exceptional breathability, built-in stretch, and all-day comfort. It dries in minutes, offers UPF 50+ sun protection, and moves effortlessly whether you're on the water, traveling, or spending the day outdoors.
Instead of loading it with oversized pockets, magnets, and unnecessary features, we kept what matters. A single chest pocket provides just enough storage without cluttering the design, while hidden collar snaps keep the collar looking sharp in the wind without changing its clean appearance.
The result is a timeless shirt with a vintage-inspired look and modern performance. Light enough for the hottest summer days, comfortable enough to wear from sunrise to sunset, and versatile enough to become the one shirt that's always packed first.
Built for long days. Designed to last. Made the way a shirt should be.

THE CASTAWAY
BUILT SIMPLE.
The best shirts aren’t the ones with the most features. They’re the ones you reach for every time you walk out the door. The Castaway was built around one idea: make a shirt the way it’s supposed to be made. Clean lines, premium fabric, and nothing extra to weigh it down. Light enough for the hottest summer days, and sharp enough for anywhere the day takes you.
LIKE IT SHOULD BE.
F.A.Q.
FABRIC CARE
How do I wash wool pieces?
Spot clean when you can. For bigger washes, use cold water, gentle cycle, and lay flat to dry. Do not tumble dry.
How do I wash technical shells?
Cold wash on gentle cycle with a tech wash (no fabric softener). Hang dry. This keeps waterproofing intact.
Can I machine wash flannels, hoodies, and fleece?
Yes. Cold wash, tumble dry low, no bleach.
Do dryers or irons damage gear?
Yes. Heat breaks down waterproof coatings and wax. Air dry everything to extend life.
How often should I reapply waterproofing?
When water stops beading on the fabric. For waxed canvas, apply a fresh coat of wax. For shells, use a spray-on or wash-in waterproofing treatment after cleaning.

Why We Do It
Fit matters in the field. We would rather you order two and end up with the right size than settle for gear that does not feel right. Every piece is built to last a season and beyond, but only if it fits the way it should.
