layer up!

A great top layer for the springtime, gilets will keep your core warm without the risk of overheating

- Lucy Miller

Whether you're hiking, running or cycling, a gilet is a versatile workout wardrobe staple. And, thankfully, some of our favourite fitness brands are offering this essential outdoor layer to set you up nicely for cold morning runs as well as the warmer days that aren't quite warm (or dry!) enough to go without a top layer. From lightweight bodywarmers, to thicker garments, we've tried and tested the most stylish gilets. They're both functional - in that they'll keep you warm on your walk to the gym and minimal, so comfy enough for when you pick up speed on your run. As you'll discover, gilets aren't an unnecessary exercise 'extra' but a great investment for this time of year, as they leave arms free to sprint or scramble while keeping you warm to the core.

Lululemon Another Mile Vest

This vest is just gorgeous! It was the most flattering gilet I tested, giving an elegant twist to my run. I also loved the good level of warmth, thanks to the bottom zipped layer that not only kept everything snug but could be removed via dickie zips if I got too hot and just wanted to wear the outside layer. I loved the removable hood, too - a rarity among the vests I tested.

The generous zip-fastened pockets were ideal for keys and storing gloves, and I loved the hidden-phone sleeve. It was a great option for running in cold weather - it kept me warm enough without causing me to overheat, and was also handy (and trendy) for taking the kids to school before my run without looking like 'that running mum'. The peplum shape was ever so flattering on my pear-shaped body, clinching me at the waist and flaring out over my hips.
