This piece in detail ＋
Good to know
- 100% organic cotton certified GOTS, from fibre to finished garment.
- A buttoned collar you open or close depending on the temperature, something a classic crew neck can't do.
- The buttons add interest to a simple piece: a notch smarter than a T-shirt, without being stuffy.
Material & feel
Organic cotton knit, nothing else: soft to the touch, it absorbs sweat instead of keeping it against your skin. You can wear it from morning to night without that clammy feeling of synthetic blends. And it takes a hot iron: the button placket quickly looks crisp again.
When to wear it?
Cool in-between-season days, when a T-shirt isn't enough and a jumper is too warm. In winter, as a base layer under a chunky jumper, collar open as soon as you walk into a heated room.
Fit & sizing
The straight fit leaves room at the chest and shoulders: you can raise your arms, bend down and add a layer on top without feeling tight.
We recommend you take your usual size.

Size M · White
This long-sleeved t-shirt is exactly what I was hoping for: comfortable, well cut and good quality. Just one small downside: I was surprised by the length of the elasticated part at the ends of the sleeves, which tightens around the wrist and forearm. It takes a bit of getting used to, but it doesn't take anything away from the overall comfort.
