The IOS TURTLE combines the elegant look of a knitted sweater with the comfort of cutting-edge fabric technology.
Our exclusive Luxury Performance Cotton blends premium natural fibres with durable performance fibres. Cotton provides a naturally soft feel, TENCEL™ makes the knit exceptionally soft while improving moisture regulation, polyamide ensures the sweater retains its shape over time and prevents elbows and cuffs from stretching out, while the fine silk content gives the fabric its elegant appearance, additional lightness and natural temperature regulation.
The result is a modern knitted sweater that is guaranteed not to itch, feels exceptionally comfortable and always looks refined.
The modern high neck replaces the classic turtleneck with a cleaner, more contemporary silhouette. Smart enough for business, relaxed enough for everyday wear.
The IOS TURTLE is made from 50% cotton, 25% TENCEL™, 17% polyamide and 8% silk.
Innovative Luxury Performance Cotton combines the natural comfort of premium fibres with the shape retention of modern performance fibres.
Machine wash at 30°C on a gentle cycle. Dry flat. Do not tumble dry.
The IOS TURTLE features a modern, slightly fitted silhouette without feeling restrictive. The elegant high neck creates a refined, contemporary look and makes it the perfect alternative to a shirt or a traditional turtleneck.
Whether paired with a blazer, chinos or jeans, the IOS TURTLE adapts effortlessly to every occasion.
Our model is 175 cm tall, weighs 78 kg and wears size M.
Does the IOS TURTLE itch?
No. Thanks to the absence of wool and the high proportion of cotton, TENCEL™ and silk, the IOS TURTLE is guaranteed itch-free and exceptionally skin-friendly.
Does the sweater stretch at the elbows?
No. The integrated polyamide stabilises the fibre structure and significantly reduces the typical stretching found in traditional knitted sweaters.
Can I wear the TURTLE to the office?
Yes. The modern high neck looks noticeably more refined than a sweatshirt while feeling more relaxed than a shirt—ideal for business, travel and leisure.
