THE SCIENCE IN THE FABRIC
The Isaac Shirt is made with our Oxtera fabric, which combines premium cotton with technical fibers to provide stretch, breathability, and wrinkle resistance.
Oxtera is a stretch woven fabric comprised of 70% Cotton, 27% Polyester, 3% Elastane.
The Physics of Fit & Sizing
Fit isn’t guesswork—it’s geometry.
The Isaac Shirt is calibrated for comfort and motion through strategic seam placement, advanced stretch recovery, and proportional grading across extended sizes.
The Isaac Shirt is true to size, with plenty of room in the torso. Due to the stretch of the fabric, men with bigger bellies should be able to wear this comfortably.
The sleeves of the garment are fitted for a more tailored look. This may require a little adjustment period for men with bigger arms, but the stretch of the fabric keeps the garment feeling comfortable while showing off your biceps.
This garment comes in a Tall size, which adds an additional 2.5" to the length of the garment and 3" to the length of the sleeve.
The Chemistry of Care
Every formula needs balance. Oxtera farbic is engineered for performance and longevity, but a little mindful care keeps it's molecular structure, and your comfort, intact.
