Fabric, fit, and daily use
Sport combines a softer modal-based fabric with a more supportive construction, so movement does not push the pair out of place.
Fabric
Modal-based blends chosen for softer handfeel with enough recovery for daily movement.
Fit
Slightly more supportive pouch and leg opening so the pair stays put across a moving day.
Use case
Walking, commuting, light gym, active workdays, weekend movement, and gym-bag rotation.
Questions
Sport FAQ
Is the Sport collection for gym training?
Sport is positioned for light movement and daily activity, not heavy compression training. For high-intensity workouts, compare the exact fabric, fit, and support details before ordering.
How is Sport different from Modal?
Modal is softness-first. Sport is the better line to compare when movement, commute, and breathable structure are the main concern.
What should I check before buying Sport?
Check the product guide, fabric notes, size guidance, and QA section on the product page.
Who should choose another Formday line?
If your day is mostly seated and softness matters most, choose Modal. For warm, humid conditions, choose Ice. For the lowest-bulk seamless feel under trousers, choose AURUM.
Which Sport should I start with?
Start with S500 AeroMove Modal — the current daily light-movement pair in the line.
Is Formday Sport a compression product?
No. Sport is built for daily light movement and comfort, not high-intensity compression. It is a supportive daily boxer brief, not performance gear.
