Product information
This is a lightweight, comfortable tee built for long days outside. It’s soft, breathable, and quick-drying, with a bit of stretch that makes it easy to move in. The fit runs a little generous, so the size guide will help you find what feels best.
The fabric is steady and durable, holds its color, and won’t shrink in the wash. It’s the kind of shirt you can wear on the trail, on the road, or anywhere you spend time outdoors.
Made from 95% polyester and 5% spandex, the material meets the highest ultraviolet protection rating under the AATCC TM 183 test. We can share the documentation if you ever want to take a look.
Our shirts are sewn by our trusted team in Vietnam and they understand the importance of quality and attention to detail. Each one is sewn to order within a couple of days, then shipped by air to the U.S. and handed off to USPS. Expect orders to arrive within 10 to 15 business days, though busy seasons can take a bit longer. We appreciate your patience. Making each shirt one at a time is part of how we keep things thoughtful.
This tee is easy to care for. Machine wash it on warm and tumble dry on a cool setting. The fabric dries fast, keeps its color, and holds its shape without shrinking. No ironing needed — just wash, dry, and it’s ready for your next day outside.
