Batch No.15 is a classic, regular fitting overshirt that skims over curves, finishes flatteringly on the hips and allows for lightweight layering underneath. Available in sizes XS to XXL. We recommend taking your normal size. If you prefer a looser fit or want to wear chunky knits and still wear your buttons closed, then size up. To find your best fit, compare our Mayfly measurements to an overshirt or jacket you already own. Lay it flat, buttoned up and take all measurements from the outside of the garment and compare with our size chart. If you’re unsure or need any advice at all, please drop us a message and we’ll be happy to help.

Our model, El, is 5 foot 5 / 165cm and wears a size Small Mayfly Overshirt. She also wears a Small in all of our other jackets.

The Batch No.15 Mayfly Overshirt is made using 100% Portuguese cotton flannel. It’s tight weave makes it tough and keeps the wind out, whilst also staying breathable. And because of the subtle brushed finish, it’s super cozy. Perfect for the summer evenings once the sun has dipped. Oh yeah, and the fabric is yarn-dyed which gives the Mayfly a sharp look. To keep your Mayfly looking its best, hand wash or machine wash at 30 degrees, then hang to dry. If needed, iron inside out or steam to take out creases.

Each overshirt will be made to order and will be shipped at the end of July. Once your Mayfly is dispatched, you'll receive an email with tracking details. We ship all over the world (72 countries and counting). And if you’re based in the EU, we will be sending your jacket directly from Portugal so that you won’t incur additional customs fees. All other jackets will be sent from the UK.

If for any reason you wanted to return your jacket, we accept returns within 28 days of delivery as long as the jacket is in perfect condition.

We’ve recently introduced a new way to pre-order a jacket. You can now split your payment into two, paying 50% (plus shipping) now to guarantee yourself a jacket, and 50% a month into your jacket being made. If you’d like to purchase a jacket with a split payment, please use the code ‘50/50’ during checkout.

We’ll follow up for the second payment around the 30th of June. Please note - If you do not complete this second payment, your jacket will not be shipped and your first payment will be refunded. If you have any more questions, please get in touch.
