PUMP! Underwear
The Complete Guide
The brand, the styles, the fit and how to spot the real thing — from an official UK stockist that has carried the full PUMP! range since 2010.
PUMP! is one of the most asked-about names in men's underwear — and one of the most misunderstood. Is it worth the money? Does it run small? How do you know you're buying genuine PUMP!? This is the guide we wish existed when people first start looking.
We've been selling men's underwear since 2006 and have been an official UK PUMP! stockist since 2010 — across more than 4,830 verified Trustpilot reviews. Here's everything you need to know.

Low-rise with the contoured pouch front and centre, PUMP! briefs are the everyday workhorse of the range — supportive, clean under clothing, and offered in the broadest spread of colours and prints. The anatomically designed pouch holds its shape wash after wash, and the signature wide waistband stays put rather than rolling.

A longer cut in stretch fabric for men who want a little more coverage without losing the support. The leg sits flat and stays in place, making PUMP! boxers equally at home in the gym and under tailoring.

This is where PUMP! arguably does its best work — and the style we're best known for in the UK. The jockstrap was originally an athletic support garment, and PUMP!'s construction reflects that heritage: the wide waistband stays locked in, the contoured pouch supports without restriction, and the open back gives full freedom of movement. Mesh versions breathe brilliantly for training, and look as good as a fashion piece as they perform in the gym.
"Athletic performance with bold, confident design — underwear engineered to work as hard as it looks."
The PUMP! philosophy, since Montreal 2010
Minimal coverage with a properly supportive front pouch — not an afterthought design. Popular for warm weather, under slim trousers, and for anyone who simply prefers the cut.

PUMP! swimwear is a serious part of the range, not a sideline. Low-rise swim briefs in quick-dry microfibre with UPF sun protection, cut with the same athletic, contoured aesthetic as the underwear.

Sizing & Fit: Do They Run Small?
PUMP! is cut closer to the body than most high-street brands — form-fitting by design rather than small. The fabric has good stretch and adapts well, but if you're between sizes and prefer more room, size up. Always measure your waist rather than going by your jeans size.
| Size | Waist (inches) | Waist (cm) |
|---|---|---|
| Small | 28–30" | 71–76cm |
| Medium | 30.5–32" | 77–81cm |
| Large | 32.5–34" | 82–86cm |
| XL | 34.5–36" | 87–91cm |
Note that XL is currently the largest size in the PUMP! range.
Is PUMP! Underwear Just for Gay Men?
It's one of the most common questions we get, so here's the honest answer: no. PUMP! has a strong and loyal following across the LGBTQ+ community, and the brand is proud of that — but its appeal is rooted in quality, fit and performance rather than any specific identity. Athletic men, gym-goers, and anyone who wants underwear that genuinely performs and looks good wear it. Buy what fits well and makes you feel good; that's the whole brief.
How to Spot Genuine PUMP!
Counterfeit PUMP! is common on marketplace platforms — eBay, third-party Amazon sellers and similar. These aren't genuine, aren't made to UK safety standards, and won't match the real product on fabric, fit or durability. Authentic PUMP! has sharp, crisp logo branding, premium stretch fabrics that feel both soft and structured, and arrives in official PUMP! packaging.
The simplest rule: PUMP! does not authorise retailers to sell on marketplaces, so any marketplace listing — especially a heavily discounted one — is not an approved seller. BANG&STRIKE has been an authorised UK PUMP! stockist since 2010, buying directly from PUMP! and stocking 100% genuine product only.
