Fenn Seamless Tank
Seamless build. Air-light weave. Nothing in the way.
A seamless training tank cut for lifting, running and hot-weather sessions. The knit is built in one piece — no side seams to rub — with mesh ventilation through the back and a compression fit that holds its shape wash after wash.
Features
- Seamless one-piece knit construction
- Open armholes for full shoulder range
- Air-light breathable weave
- Mesh ventilation panels
- Supportive compression fit
- Shape-retaining, wash after wash
Polyester / elastane performance blend. Machine wash cold on a gentle cycle, hang dry. Do not bleach or tumble dry.
Thoughtfully designed by Activevora.
