A highly breathable, half-zip, active t-shirt constructed from innovative Polartec® Delta^™ cooling fabric. Suitable as a versatile layer for activity in intense heat.

This breathable, half-zip t-shirt is the perfect antidote for arid conditions. Constructed from innovative Polartec® Delta fabric, the Oryon half zip t-shirt is a new experience in layering and can be worn as a base layer or sole layer as required. is a cooling technology designed to sit next to skin for enhanced moisture-wicking and fast-drying capability.

Delta works more efficiently than conventional fabrics by elevating touch-points so that the fabric sits ever so slightly raised, rather than directly lying flat on the skin. This increases airflow, hastens moisture dispersal, and reduces the cling of the fabric when wet.

A clean design intended to mitigate the attrition of arid environments, the Delta T-Shirt prioritises the efficiency of fabric construction over features and details.

Using semi-lock zips, a half-zip has been included to maximise ventilation capacity as required. Two zipped chest pockets and mesh backing serve an effective dual purpose for either storage of expedition essentials or additional ventilation.
