A half-zip is the pullover you end up reaching for on repeat, and this one earns the spot with a smooth, fine knit that sits flat under a collared shirt and looks just as sharp on its own. The high collar closes off the neckline on cold mornings, then opens with a single pull of the zip once the office heating kicks in.
An easy knit that makes a Monday outfit look planned.

Customer feedback
Daniel M.
The shirt fit better than expected and worked straight away with trousers I already had. Easy piece to dress up or wear casually.
Marcus T.
The overall look is clean and the sizing felt consistent. I bought one piece first and came back for two more a week later.
Ethan R.
What I like most is that it goes with almost everything. The cut feels modern without being overdone.
Oliver J.
I ordered this for summer and ended up wearing it much more often than planned. Comfortable, simple, and looks polished.
Nathan C.
The style is clean and easy to wear, which is what sold me. Delivery was smooth and the piece looked like the photos.

The colour and fit were both spot on. It has that versatile look that works for dinner, weekends and holidays.

This was my second order from Sir Casil and the consistency is what I appreciate. The pieces make getting dressed easier.

I wanted something casual that still looked put together. This landed right in that sweet spot.

The checkout was simple, the order arrived within the expected window, and the item was exactly what I hoped for.

It gives a sharper look without feeling stiff. For the price, I’m genuinely happy with how it wears.
