The world of outerwear isn’t as simple as it seems. Those of us in the UK know that our temperamental weather means that there is a demand for variations in our coats and jackets. From belted wool styles to quilted, puffer and double-breasted, full-length numbers, it’s not just about style—there’s a huge element of practicality in there, too. So where do we even start? I went to COS, one of the premium high-street brands that is relatively reliable in its offering of quality clothing, to find coats that are worth investing in. After checking each one over in real life and reading the composition labels, below, I tell you exactly what they’re good for so that you can have realistic expectations of what you’re buying. Keep in mind that not all coats are created equal, and my picks are certainly not made for the same purposes. 

The Best COS Coats for Winter


This is one of the few full-length coats that COS offers that is 100% wool (bar the interior, which is undisclosed but very clearly backed with a synthetic material, which is quite normal). The funnel-neck detail provides defence from the cold, and the beautifully constructed interior means that the coat holds a straight and minimalist silhouette. It’s particularly useful for chilly, windy conditions as there are no openings—unless you style it that way—and it looks very smart. Wear it with knee-high boots and statement earrings, and the coat is chic enough to carry your entire outfit.

The robe style has been incredibly popular for a while now. It usually features minimal hardware and a simple, belted closure. Because of the lack of complexity in styles like this, I’d suggest focusing on the weight of the material—too thin, and it won’t do much good against single-digit temperatures. I’d also look at the purity of the fabric, with a focus on 100% natural wool. COS has brought this out in the most gorgeous, rust-toned beige as well as classic black.

It is composed of a mix of wool and lyocell. Lyocell is a relatively new innovation of manufacturing viscose (a semi-synthetic made of wood pulp) in a more circular way. This means that creating this fibre involves recycling almost all of the chemicals used and sourcing its cellulose from renewable forests, to avoid desertification and polluting the environment. On the plus side, it is a more affordable option for those looking for a timeless coat, but the only consideration is that the lower percentage of wool means that this is very much a transitional piece and won’t be suitable for truly cold winter weather.

It seems that none of us are quite over the popular scarf coat, and when there are styles this cute, fair enough. The polish of this coat with its subtle pinstripe flair is just the thing I’d want to wear on the morning commute when I’m in need of a little brightening up. It’s also just the thing to throw over an evening outfit when you’re wondering how to keep things elegant without freezing all night. For this full-length outerwear, the lyocell added to the wool enhances the drape of the material, so it sort of resembles a cape and definitely looks more expensive than it actually is. This won’t be the warmest option, as whilst there’s wool in the mix, it’s not particularly thick or high in percentage, so this is really most suitable for popping on when you're in and out.

If you love the look of a scarf coat but don’t want to commit to a full-length statement, this is a beautiful and pared-back option in deep navy. A coat like this will look great with literally anything, although this is, again a transitional option. The 60% wool and 40% lyocell mix has a lower environmental impact than a synthetic blend, but it means that this option leans more towards style than substance in terms of keeping you warm. The plus point with this piece (and all of the wool used in the coats featured here) is that they come with the Responsible Wool Standard (RWS) certification, which is a protective measure for merino sheep, ensuring ethical shearing practices.

Most of us just want a coat we can grab and pull on without thinking too much about it. As long as the weather stays in the high single digits, this is an ideal silhouette. Whilst it’s not the warmest composition (a mix of wool and lyocell), the oversized style means that it’s easy to throw over thick layers. It has a boxy shape and a lovely, brushed-wool texture, which would look great with a cream, turtleneck jumper and baggy jeans.
