This stylish Regatta waterproof jacket is down from £80 to £21.60 with extra discount

A good waterproof jacket is one of those wardrobe essentials you don't always think about until the rain starts falling. With the weather becoming increasingly unpredictable as summer gives way to autumn, having a lightweight waterproof layer ready to throw on can make all the difference.

The Regatta Women's Bayletta Waterproof Jacket is currently reduced from £80 to £24, giving shoppers a huge 70% saving. But there is an even better deal available as if you use code TAKE10 at checkout you’ll get an extra 10% off, taking the price down to just £21.60.

Available in sizes 8 to 26 and 16 colours, there’s plenty of choice, with shades including pink lemonade, four leaf clover green and sonic blue. Just bear in mind that not every colour is discounted to the same level, so the £24 price applies to selected options.

At £21.60 with the code, however, this is a particularly tempting time to pick up a jacket that could become one of those pieces you reach for whenever the forecast looks uncertain.

The Bayletta jacket is designed to combine practical rain protection with a more stylish everyday look, meaning you don't have to sacrifice how you look just because the weather has other plans.

It uses waterproof and breathable ISOTEX 15000 fabric, with a 15,000mm hydrostatic head and durable water-repellent finish. The fabric is also windproof, while taped seams are designed to provide complete waterproof protection, making it a useful option for wet and blustery days.

There is a soft jersey lining for added comfort, along with a recycled polyester taffeta lining, so it is designed to feel pleasant to wear rather than like a purely functional rain layer.

The adjustable details are another useful feature. The grown-on hood has drawcords, while the waistband has an inner drawcord so you can adjust the fit around your waist. There are also adjustable cuffs and two lower pockets for those everyday essentials you don't want to carry in your hands.

One five-star reviewer was particularly impressed with the thoughtful hood and adjustable waist, writing: "Perfect. This is a great raincoat! The hood has the small peaked bit to actually stop your fringe getting wet and the waist is adjustable to add shape."

Another shopper kept things short and sweet, describing it as a "Great little jacket" and praising its lightweight and stylish design, adding: "Cool."

Those comments highlight exactly why a jacket like this can be useful for more than just walking the dog in a downpour. The Bayletta jacket is designed to work for city strolls, weekend outings and the daily commute, so it can easily become part of your everyday wardrobe.

The lightweight construction also makes it a useful layer to keep close by when the forecast is changeable. It can be packed away for a day out, worn over everyday clothes or used as an outer layer when the temperature starts to dip.

And while waterproof jackets are often bought for practicality rather than style, the Bayletta jacket's adjustable waist means you can create a more shaped silhouette. Plus, with 16 colours to choose from, there is also plenty of opportunity to pick something that works with your existing wardrobe.

The biggest attraction right now, though, has to be the price. At £80 originally, the £24 sale price already represents a 70% saving. Add code TAKE10 and you'll save another £2.40, bringing the final price to £21.60.

As autumn approaches and rainy days become more frequent, this could be the kind of practical layer you find yourself reaching for again and again.
