Pentagon Sierra Polo Shirt
- Almost gone!
Goes well with

The Pentagon Sierra is the plain one, and that is the point. It is a 180gsm 100% cotton piqué polo in a comfort fit, with no logos across the chest, no contrast panels and nothing to date it. If you are kitting out a team or need something that passes as uniform without looking like a uniform supplier picked it, this is the one.
Cotton piqué is the traditional polo fabric for a reason: the waffle-textured knit holds air against the skin so it breathes rather than clinging, and it softens with washing instead of going shiny. At 180gsm it is substantial enough to hold its shape through a shift and repeated laundering, without being a heavy shirt in summer. The cut is deliberately relaxed rather than fitted, so it moves when you do and stays comfortable across a long day on your feet.
Detailing is minimal: a three-button placket, ribbed sleeve cuffs that keep their shape, an orange Pentagon tab inside the collar and another at the hem. The chest is completely plain, which makes it straightforward to embroider with a name, unit or company mark.
