Description
Leon Open Knit Lightweight Polo | Open Knit | Castielli
The Leon polo in navy blue is an open knit with a clean silhouette and a relaxed collar that lies flat without pressing. Air passes straight through the fabric, which makes it the shirt for the hottest weeks of the year.
Why you'll reach for it
- Open knit structure: visible breathing room in the weave keeps you cooler than any solid fabric of similar weight.
- Refined drape: the knit falls straight and skims the body rather than clinging in the heat.
- Relaxed collar: soft, unfused and made to be worn open.
- Quiet styling: no logos and no contrast tricks, just texture doing the work.
Fit and fabric
Regular fit in EU sizes XS to 2XL with a hem that sits at the hip, made to be worn untucked. True to size. Layer a plain tee underneath if you prefer more coverage under the open weave, or wear it alone on the warmest days.
Care
- Machine wash cold on gentle in a mesh bag.
- Dry flat; hanging stretches an open knit out of shape.
Shipping & Delivery
Shipping & Delivery
Orders are dispatched within 48 hours, and delivery within Europe takes 5 to 7 business days from your order, with a tracking link by email the day your parcel ships. Standard tracked shipping is free.
Returns
Returns
You have 30 days from delivery to return a piece, unworn and with the tags attached. Write to support@castielli.com with your order number. Return shipping is paid by the customer unless the piece arrived damaged or incorrect. For another size, the fastest way is to return it and order the new size.
Care Instructions
Care Instructions
Check the care label inside each piece for its exact instructions. As a rule: knitwear by hand in cold water or on the wool cycle, dried flat; cotton on a cold, gentle cycle; suede brushed with a soft dry brush and kept out of heavy rain.

The Fabric
Natural fibres, chosen by season
Extra-fine merino and cashmere for the cold months. Every piece starts from the fibre that behaves best in its season, cut with room to move and finished to hold its line.
The Craft
Details you notice on the tenth wear
Reinforced seams and hems finished straight. Ribbing that springs back after a full day. The kind of detail you check after a season of wear, and it is still there.
