This ultralight shirt is constructed from Deltapeak™ on the body and Justice™ on the sleeves to maximize airflow. The sleeves are tight, ensuring they don't ride up. This shirt is ideal for runs in mixed conditions. Can be worn alone or as a mid-layer.

- Deltapeak™ / Body
Deltapeak™ is developed by a Japanese textile company which has been producing fabrics since the late 1800s. This technical fabric is knitted which gives it a 4 way stretch and a soft, natural texture. With its fast-dry, anti-odor, and UV resistant properties, we use it in our running tops to ensure comfort in warm conditions.

- Justice™ Multi-Stretch Tech-Silk / Sleeves
Our proprietary Justice™ technology was developed in house. This unique synthetic fabric is produced in France by a natural silk maker whose business was founded in 1839 and pivoted in the 1960s to technical and elastic yarn manufacturing. Borrowing from medical technology, Justice™ is highly durable and resilient, but has a feel of silk and an incomparable lightness. It stretches naturally in every direction, following the body movements while staying breathable. Justice™ dries astonishingly quickly, preventing bacteria from mixing with your sweat and staying odor free.
All shorts linings are made from Justice™ and feature clean cut edges for maximum comfort and lightness.

- Bonded seams / Sleeves
Bonded seams means flat seams which ensure extra fabric doesn't rub against your skin and reduces the weight of the product. This technology uses high-temperature heat machines to weld the seams together with an elastic invisible glue tape which stretches with the fabric.

- Flatlock Seams
Flatlock seams are made by sewing two edges of raw fabric directly together. This eliminates any extra fabric — reducing the weight of the product and eliminating chafing.

- Reflective Print

- Detachable exterior branding and care label
Tear along the perforated edge to remove the bottom portion of the label. The top part will remain on the garment
