Fabrics | Considered British Menswear | SIRPLUS

Fabrics that are made to last

Quality has been our thing since we started with those first surplus shirt offcuts. Now, we work with mills and makers worldwide who share our slightly obsessive approach to fabric sourcing.

Each material we choose has to be special - the kind that gets better with age and becomes a faithful wardrobe companion for years to come.

From Hebridean tweed to Mongolian cashmere, organic cotton to technical Ventile - discover the fabrics we're proud to work with.

Corduroy

From its workwear origins to its modern-day charm, corduroy brings texture and character to our collection. Our cord comes in both classic wide wales and finer needlecord, perfect for everything from suits and shirts to our signature chore jackets.

Lambswool

Soft to the touch and durable by nature, our British-spun wool brings warmth to this season's pieces. Drawing inspiration from Albert Irvin's vibrant paintings and traditional Fair Isle patterns, discover our new crew neck jumpers and vests.

Surplus Fabrics

This season's surplus collection features Italian wool blends with chalk stripes and robust boiled wool for our chore jackets. Our signature Nehrus complete the range, made from wool and cashmere blends.

Cashmere

The crown jewel of our collection - cashmere sourced from Italy's prestigious mills including Cariaggi. Find it across our knitwear, classic Nehru jackets, waistcoats and raglan coats, as well as essential accessories like scarves and beanies.

Harris Tweed

From Hebrides mills to London, Harris Tweed has been a SIRPLUS favorite. This season brings new pieces to the collection - discover our Nehru jackets, waistcoats and raglan coats. When they're gone, they're gone.

Merino Wool

A cornerstone of our autumn and winter collections, merino wool brings natural durability, breathability and antibacterial properties to every piece. Discover it across our suits, knitwear and outerwear, including our chore jackets.

Cotton Twill

The hardest working fabric in our range, cotton twill is durable yet softening with each wear. Sourced from Italy's finest mills including Duca Visconti, you'll find it across our suits, chore jackets and gilets.

Wool Blends

From lightweight summer pieces to robust winter layers, our carefully chosen wool blends bring something special to each piece. Wool and silk, wool and cashmere - made into shirts, Nehrus and outerwear.

Organic Cotton

Light, breathable and grown without harmful pesticides - organic cotton was the natural choice for our t-shirts, polo shirts and shirts.
