Interlock Half-Zip Polo

The polo, redefined. The BSTN Interlock Half-Zip Polo takes the polo collar and removes everything unnecessary — no buttons, no placket, just a clean half-zip in silver hardware. 290 GSM double-knit interlock cotton gives it a smooth, weighty hand feel with a fine two-sided texture — structured enough to hold shape, soft enough to wear against the skin all day. The boxy short-sleeve cut gives it the relaxed proportion that defines the BSTN aesthetic. Wear it zipped to the collar for a clean minimal look, or unzipped halfway for off-duty ease. Available in Slate Grey, Black, Sage Green, and Off-White.
