Most polo shirts age badly. The cotton versions go thin at the collar, lose their structure after a season, and end up looking like something you wear to wash the car. Wool is different. A well made wool polo actually improves with wear, developing a softness and drape that makes it look more considered the longer you own it, not less.

We’ve been looking specifically at merino and lambswool options that sit properly in the collar, hold their shape over a shirt or worn alone, and work across the kind of occasions where a full knit feels like too much but a t-shirt feels like too little. That middle register is where most of us are actually dressing.

The weight matters. Too light and you lose the point of wool entirely. Too heavy and it becomes unwearable from April onwards. These are the ones that get the balance right and reward you for buying them properly the first time.
