Category: Mens Knitwear Sweaters

A signature silhouette, reimagined in our most luxurious fibre blend. The Cassum Half Zip honours the style we’re known for, effortless, versatile, quietly refined.

Crafted from a considered blend of Merino, Possum, Cashmere and Silk, it delivers remarkable warmth without weight. Soft against the skin and naturally breathable, it invites all-day wear, whether layered beneath a coat on crisp mornings or worn alone as the air cools toward evening.

Finished with our signature kite zipper, the neckline can be adjusted with ease, worn open for a relaxed feel or zipped high for added warmth. It’s a small detail, but one that speaks to thoughtful design and enduring craftsmanship.

A piece that feels as at home outdoors as it does across the table at dinner. Reliable. Elevated. Made to be reached for, season after season.

Customer Reviews (4.8 / 5 · 5 reviews)

Adam ★★★★★

The half-zip sits perfectly on the chest without pulling, and the fabric has just enough weight to feel substantial without being heavy. I tossed it on for a casual dinner and got two compliments on the rich color.

Edward X. ★★★★★

The half zip sits perfectly at the collar, not too tight or loose, and the drape is exactly what I hoped for—structured but relaxed. I've worn it twice already and it holds its shape after hanging overnight.

Chloe O. ★★★★★

The fabric blend feels noticeably heavier and more substantial than my other sweaters, drapes really nicely without being stiff. Wore it out for the first time today and got a couple compliments on the half zip detail.
