INSULATED JACKETS

For post-swim or pre-race warming, an insulated jacket can be an inspired purchase. We put four synthetic options to the test

Insulated jackets have become popular over the years for their warmth, practicality, and style, and you're just as likely to see them worn to a pub as you are in the outdoors.

But they're a great compliment to a triathlete's gear cupboard, too. Especially for early mornings when waiting around before a race or for warming up after a bracing outdoor swim.

The four on review here are being tested primarily on their warmth, for obvious reasons. We've considered the amount and quality of the insulation, its ability to loft, and how well the jacket keeps warm air trapped inside. We've also looked closely at the fit of each jacket, the features on offer, and their eco-credentials.

For this test, we've decided to focus exclusively on synthetic-insulated options. This is because, in addition to the ethical questions around the duck and goose down, we felt synthetic fiber's ability to stay warm when wet is essential to a triathlete. Every jacket on test is also available in both men's and women's versions. Let's get testing...
