Story & heritage

The BB1 polo is linked to Björn Borg and FILA’s White Line tennis era. Specialist tennis retailers describe it as a 1970s Borg design, while FILA’s broader history records the brand’s 1973 move into sportswear through its Borg endorsement.

Its pinstripes, contrast placket and F-box chest logo make it one of the clearest garment icons in FILA’s archive.

Materials & craft

Retail descriptions emphasise vertical pinstripes, contrast tipping on the collar and sleeves, a snap-button placket, side vents and the F-box at the chest. Vintage listings commonly identify cotton versions of the shirt.

How to choose & style

Wear it tucked into pleated shorts for the court reference, or open at the collar with straight denim. The shirt looks best when the red-navy placket is the only loud detail.
