CUSTOMER REVIEW

Simply Amazing

"Why have I not bought these before? Used in a recent 50km ultra marathon and they were excellent. The boxers supported in all the right areas and were super comfortable." Abdul S, UK

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

Great product

Repeat customer.
Great boxers that look after my big thighs from rubbing and causing painful chafing.

Great customer service aswell when I got a bad pair that needed replaced.

Happy runner

Bought for my husband who has completed the couch to 5k and has now caught the bug and started doing 10k runs. Very happy with these as they are actually his second pair.

Fine garment (and fit, this time)

Used size L boxers in training and on a half marathon at the weekend, hit my goal of sub 2hrs. No sweat feeling or itching or adjusting the garment. Great.

One thing I will say about sizing as a 34" waist I bought briefs in medium previously as I'd worn them that wasnt money well spent, they were too cutting. So in my opinion go for the "looser fit" on the scale.

Oh for a looser waist

Superb quality but why oh why do we have to have a think, strong elastic waist ion the larger sizes? It does NOT look trendy and an overflowing bulge is ugly and uncomfortably. Waist elastic needs to be half the size.
