For small-batch items such as Cords, Shorts and Lightweights - we just get one delivery per season and don't tend to restock these between seasons. Our stock levels do fluctuate though, so we'd still suggest popping yourself on our waiting list for a restock notification - that way, we can let you know if it comes back.
For our core range - such as Navy Heroes and Black Sharps - we restock on a rolling basis.
To get notified when your item is back in stock, just use the 'Size not in stock?' option on any product page and fill in your details. Alternatively, you can drop us a line to firstname.lastname@example.org, and we'll let you know when your favourites are due back in.
