Wonder pants!
"I love these Runderwear pants. At 50 I’ve tried a lot of running underwear and have ended up resorting to nothing. Not in this case! These are light, stretchy, well-fitting and I don’t give them a moment’s thought while out running. Given that I’m hill and trail running, with plenty of extending, stretching, scrambling over things, I’d say I couldn’t ask for more." - Lesley M
Seamless Design
The underwear is created on a 360° seamless machine from a single piece of fabric, which means no side seams or labels. This significantly reduces the risk of skin irritation and minimises wastage during the production process versus the traditional cut and sew method

Moisture-Wicking
The technical fabric has excellent moisture-wicking properties to remove sweat from your skin quickly. It has been extensively researched and tested to maximise performance, helping you stay dry and comfortable - even during the most intense exercise

Breathable Fabric
The performance fabric is lightweight and breathable, with carefully positioned micro-perforations incorporated into the design of each underwear style. These maximise airflow and optimise core temperature control, helping you to stay cool in any conditions

Ergonomic Fit
Specifically engineered for runners, by runners to deliver the ultimate experience in comfort. Durable fabric with 4-way stretch movement allows you to run freely and provides support to your body, making it the perfect first layer against your skin

Ordered online, delivered in plain packaging and arrived the next day. Fabulous underwear, so comfy and really like the navy colour too. Wore them for the first time running last weekend and they stayed in place and felt good. Would definitely recommend.

Having read reviews I ordered a size up. Usually a 12. Perfect fit, so comfortable. Worn for a pretty tough mountain expedition in a very warm climate. No issues at all. Definitely my go to underwear for anything similar or general training. Thanks

These are ridiculously comfortable. Very smooth, light and fitted. Great for workouts and running! Wish I ordered them sooner.
