The WILLIT Aero Sun Collection is made for bright, warm days when coverage should feel light and easy. With UPF 50+ protection, quick-dry comfort, and Polygiene® odor-control technology, these are the styles that help you stay covered, comfortable, and fresher for longer.
It is an advanced odor-control technology derived from natural silver salt. It safely prevents the growth of odor-causing bacteria right in the fabric tracking, so your shirt stays fresh through long hikes, golf rounds, or travel days. It is completely skin-safe, hypoallergenic, and active only on the textiles, allowing you to wear more, wash less, and save water.
Our UPF 50+ protection is engineered directly into the micro-grid weave of the fabric, blocking up to 98% of harmful UVA and UVB rays, and it'll remains fully effective no matter how many times you wash it.
The secret is our inner Micro-Grid technology: a subtle texturized weave that lifts the fabric just millimeters off your skin to maximize airflow and eliminate that sweaty, clingy feeling.
We’re accredited by bluesign, which promotes consumer safety, low impact manufacturing and responsible use of resources; Oeko-Tex Eco-Passport which supports responsible manufacturing and supply chains; and we have REACH compliance, the EU’s chemicals legislation. Polygiene was also a winner in the 2019 Scandinavian Outdoor Group Awards.
