How we tested the best sweatpants

Our team of reviewers are experienced testers of all manner of fitness kit. While testing out these sweatpants we were mainly looking at fit, comfort and style. We also paid close attention to the fabrics used and whether they offered specific sporty features like 360-degree stretch or moisture-wicking abilities, alongside any additional features, like pockets, drawstring waists and elasticated cuffs.

The soft-knit internal drawstring waistband sits comfortably without any digging in

Under Armour OutRun The Storm Pants performance

They’re made from a four-way stretch woven fabric that we found to be light and flexible. Plus, even though they’re close-fitted and tapered, we found they flexed and moved with enough freedom to handle everything from sprint intervals to sets of high knees.

They’re built for cold-weather workouts and that’s definitely where they perform best. And though we did experience good breathability here, in milder conditions they can run a bit hot.

Under Armour OutRun The Storm Pants extra features

For storage, there’s a central rear expandable pocket – Under Armour’s Speed Pocket. We would say the hooded holder is great for stashing a larger smartphone or a headphones case securely without any irritating bounce. It’s water resistant, too, so your precious tech has extra protection.

The soft-knit internal drawstring waistband sits comfortably without any digging in while the tapered legs have ankle zippers that make these ideal for slipping on and off fast, without removing your shoes, either side of a workout. There’s some really nice details here too, with big zippers that clip and stow upwards, making them easy to grab when you’re tight after that long Sunday run.

The UA OutRun The Storm Pants come in three colour options – black, light and dark grey – with a small reflective detailing for added visibility on night runs. And there are six sizes from S to 3XL.

Overall, we found them to be stretchy and comfortable, with unique wind- and water-resistance features making them perfect for cold and rainy workouts – unlike most traditional sweatpants.
