UPRO men's underwear covers three core cuts: briefs, boxer briefs and jockstraps. The difference is coverage and support, not quality — choose by how much leg coverage you want and how much support you need.
All three cuts come in sizes M–XXL and are sold individually, so you can mix colours and cuts freely. Briefs and jockstraps are $24.90, boxer briefs are $26.90. Check the size chart on each product page before ordering, and read the fit and size guide if you are between sizes.
Briefs: minimal coverage, cleanest fit
A brief is the cleanest underwear cut: a low rise, a high leg opening and no fabric bunching under trousers. It is the choice for minimal coverage and a close fit.
In the UPRO range, the Ribbed Brief comes in multiple colours, and the Klein Blue Ribbed Brief and Blue & White Striped Ribbed Brief use a rayon and elastane rib knit. For stripes, see the Navy Striped Brief. For details, try the Heart Embroidery Brief or the Bow Bikini Brief with tie sides.

Boxer briefs: brief support, plus leg coverage
Boxer briefs combine the support of a brief with fabric down the leg, which helps prevent chafing and keeps the fit smooth under jeans and trousers. They are the go-to cut for long days, travel and the gym.
The range includes the compact Ribbed Boxer Brief in Klein Blue, the Striped Boxer Brief with narrow navy and white stripes, and the Long Boxer Brief with a longer leg and contrasting waistband in black or white. A longer leg covers more of the thigh and is less likely to ride up.

Jockstraps: support with an open back
A jockstrap pairs a supportive front pouch with a waistband and rear straps, leaving the back open. Originally designed for sport, it is now just as popular for the gym, everyday wear and making a style statement.
UPRO jockstraps come in several constructions: the textured Ribbed Jockstrap with two rear straps, the Single-Strap Jockstrap with sheer mesh panels, the Double-Waist Jockstrap, and double-strap designs in black or blue-and-white stripes.

In all three cases, use the chart on the product page rather than a size label alone. If you are between sizes or unsure how to interpret a measurement, contact UPRO before ordering.
Fabrics, in brief
Many styles use soft ribbed and waffle-knit fabrics, often rayon blended with elastane for stretch, alongside striped, embroidered and tie-side designs. The cotton-blend Open-Hole Embroidered Brief combines 45% cotton, 45% lyocell and 10% elastane. Exact fabric composition is listed on each product page — read that page rather than assuming every style uses the same fabric.
Care, as a rule: wash cold on a gentle cycle and air-dry to protect the elastic. Follow the care label on the garment itself.
