Polo Longsleeve Slate
Our knitwear is designed with a relaxed but structured fit — true to size with comfortable room through the chest and shoulders.
If you are between sizes, we recommend sizing up for a more relaxed drape or staying true to size for a cleaner, more tailored look.
| Size | Chest (inches) | Length (inches) | Sleeve (inches) |
|---|---|---|---|
| XS | 34–36 | 26 | 32 |
| S | 36–38 | 27 | 33 |
| M | 38–40 | 28 | 34 |
| L | 40–42 | 29 | 35 |
| XL | 42–44 | 30 | 36 |
Measurements are approximate. For the most accurate fit, measure your chest at its widest point.

Our polo longsleeve in 100% Italian Zegna Baruffa Cashwool® merino. Knit to a fine 15-gauge with a classic polo collar, 1x1 ribbed cuffs and hem for a clean, tailored finish. Structured enough for every room. Soft enough for every day. Crafted in Brooklyn, New York.
Crafted from 100% Zegna Baruffa Cashwool® Extrafine Merino — an Italian yarn spun in Borgosesia since 1850. The exceptional fineness of the fiber gives each piece its characteristic softness, breathability, and lasting shape. Lightweight enough to wear against the skin, resilient enough to outlast the seasons.
The yarn inside every Eternal Overflow piece carries more than softness — it carries a standard.
Zegna Baruffa Lane Borgosesia was one of the first textile companies to put sustainability as a strategic priority, long before it became an industry trend. Since 1850, the company has operated from a single principle: quality, service, innovation, and respect for the environment — all production units located in Italy, one of the few full cycle spinners to have kept it that way. g2g2
Their commitment to traceability and responsibility spans their entire value chain, backed by concrete certifications: RWS (Responsible Wool Standard) certified since 2019, guaranteeing the wool comes from responsibly managed farms. All production runs on green electricity, and chemical management follows the strictest ZDHC protocols across the entire process. Upwork + 2
When we chose Zegna Baruffa Cashwool®, we chose more than a yarn. We chose a company that has been doing things the right way for 170 years.
Merino wool rewards careful handling. Hand wash cold with a gentle wool detergent, no wringing or twisting. A delicate machine cycle at 30°C maximum is also suitable.
Lay flat to dry away from heat and direct sunlight. Never tumble dry. If ironing is needed, use a low setting with a pressing cloth, never iron directly on the wool.
Fold, don't hang, hanging will cause the garment to lose its shape over time. Store folded in a cool, dry place.
Some light pilling may occur with wear. This is a natural characteristic of fine merino wool, not a defect. A fabric comb will easily restore the surface.
