The Windbreaker.
The T-shirt.
The Singlet.

Questions that have led us to this point:

1) Would simplifying these staples be of service to runners?
2) Can we make fabric, fit and function the focus?

We have our convictions, but we'll let you be the judge.

THE WINDBREAKER - UNISEX

The objective: Develop a unisex, packable running jacket that strikes a better balance between airiness and durability. Not snag-thin, but not weighing you down. A staple companion for unpredictable, wild & windy conditions - year round.

The solve: Lightweight (95gsm) ripstop fabric. Laser perforated air vented underarms. Two-way zip system. Adjustable waist and hood bungee.

THE T-SHIRT

The objective: Create a lightweight T-shirt that fits. Not too long, short, tight or baggy. Breathablefloaty fabrics that work with a pack and hold their shape wash after wash, after wash.

The solve: A dual fabric construction marrying a gridded stretch fabric to a mesh underarm using frictionless merrow stitching. Bonded, seamless hems. Resulting in a floaty but firm fit.

THE SINGLET

The objective: Develop long-run friendly, chafeless neck and arm holes. Tailored for male and female preferences. Fabrics that do not hold onto or are weighed down by moisture.

The solve: Bonded seams across neck and arm holes. A breathable mesh fabric forming the entire back panel.
