About Us

We are a new Montreal-based luxury fashion house specialising in exceptional cashmere knitwear for men. Inspired by our region's refined "joie de vivre” lifestyle, we have created a line of sweaters for discerning customers who appreciate quality, comfort and understated elegance. 


Passion for clean aesthetics, quality and fine workmanship

All of our sweaters reflect Thomas’ passion for simple elegance, comfort and durability. Our cashmere fibres are sourced from one of the finest and most established British cashmere yarn suppliers. We have also partnered with exceptional knitwear artisans who are manufacturing all of our products at their factory in Italy. 


Luxury Sweaters with Substance and Character

In life, one often deals with a certain amount of compromises. This is not the case at Thomas de l’Île. We believe that you owe it to yourself to invest in a real sweater, which you would like to wear as often as you could, and which would complement your preferred Swiss watch and favourite luxury car. 


If properly cared for, our 100% cashmere sweaters are designed to last a lifetime. To ensure durability, carefully selected lamb leather is used for our signature diamond-stitched elbow patches. We hope you will consider including our Thomas de l'Île sweaters as part of your estate.


Exclusivity & Limited Production

At Thomas de l’Île, we realise that you not only appreciate quality but also value exclusivity. Only a limited number of sweaters will be made available in a small number of the finest retail establishments in the world.

Welcome to Thomas de l’Île.
