Buying Guide: 3-in-1 Jackets

If you want a coat that provides both warmth and rain protection, with the flexibility to adapt to all seasons, a 3-in-1 jacket is the perfect option to suit your needs.

There’s plenty to consider when shopping for a new 3-in-1, so we’ll guide you through everything you need to know before buying. Let's get into it!

What is a 3-in-1 jacket?

3-in-1 jackets, also known as 'interactive’ jackets comprise of a waterproof outer and a removable mid-layer (usually a fleece or softshell).

During colder spells, the insulating mid-layer can be zipped or hooked into the outer layer to create a warm winter jacket. When it’s hotter outside, you can split the two layers apart and wear them individually; pop the fleece on before heading out for a peaceful stroll, or grab the waterproof shell when it’s time to ward off a downpour.

A 3-in-1 jacket represents great value for money as it can be used all year round, meeting the demand of the changing seasons in all it’s three forms.

Outer layer

It’s crucial that the outer shell of your 3-in-1 performs well in the wet. If you're forced to choose between a membrane or PU coated jacket, we suggest you go for the membrane option. Both technologies provide waterproof protection, however, a membrane textile jacket will have far more breathability. It may cost you a bit more, but if you're going to be getting active, it’s the best way to stay cool, dry and comfortable.

GORE-TEX is arguably the most famous, but advances in waterproof membrane technology have led to several other names popping up. You may also come across Polartec Neoshell, Pertex Shield, DryVent, AquaDry, FutureLight, Rain Rdy, Petrichor, Proflex, Hydroshell and eVent (to name a few) in your search for a new jacket.

Tip: Over time, the effectiveness of waterproof materials will diminish. In order to extend the lifespan of the jacket, you'll need to ‘reproof’ it.

Inner layer

The inner layer of a 3-in-1 jacket is there to trap air, hold in heat and keep you cosy. This interior section is effectively a mid-layer jacket, and will usually be made from a fleece or softshell material.

It attaches to the outer shell using a simple zip system but can be worn as a standalone jacket too.

Fleece

This soft, textured fabric may be lightweight, but it still provides much need insulation on cold days, trapping warm air as it leaves your body in order to keep you toasty.

Softshell

Softshell layers are designed with more intense activities in mind. While it may not keep you as warm as a fleece, it will provide more freedom of movement and offer greater protection from the wind and rain if worn as a top layer.
