As you’d expect, the most important thing about the outer layer of a 3-in-1 jacket is that it should always offer waterproof protection. This is achieved through either a waterproof coating or membrane. Membranes are more durable and breathable, whereas coatings are cheaper but will lose effectiveness much quicker.
The type of waterproofing depends on the brand you buy. GORE-TEX® and eVent® are used widely, but some manufacturers use their own type – IsoTex (Regatta), Texapore (Jack Wolfskin), AQ2 (Berghaus).
Top Tip: Over time, the waterproof repellent on your jacket will start to wear off and become less effective. Therefore, it’s important that you reproof it to ensure you stay dry.
The hood of your 3-in-1 jacket can be grown on or removed. A good hood should be adjustable to give you a snug fit and help protect you from the wind and rain. A peak is also useful for directing rain away from your face.
