Sizing Guide

The easy-going blazer you’ve been searching for. With an unstructured shape and relaxed detailing, the 01 BLAZER has a casual look while still offering an air of sophistication. Contrast piping and double-lined sleeves builds in an extra layer of versatility. Plus, it’s made of smooth, drapey eco fabric TENCEL™, which means you’ll look polished even if you (literally) throw it on. Pair it with the 01 SHORT for a more polished look, or if you’re into serving athleisure looks, we also recommend the 01 BIKE SHORT

Natural Fibers

We primarily use fabrics made of natural fibers like Tencel™ and cotton. We limit our use of synthetic fabrics unless it specifically supports our commitment to quality.

Sustainably sourced

All of our designs are made using deadstock fabrics limiting material waste. Our fabrics are also sourced from local markets, meaning there is less fuel usage when transporting our fabrics to the manufacturer.

Sustainable Shipping

All of our packaging options are sustainable. You can choose between 100% reusable RePacks or our compostable plastic mailer. Even our insert is eco-friendly, made from seeded paper embedded with wildflowers, which will grow once planted.
