Unpadded push-up boxers: how Hold-Up works
The words “push-up” might suggest padding. In Boxer↑Up by Kloters, they refer to built-in support. Hold-Up is made of 100% cotton, sits only at the front and provides gentle support without padding or compression. Your legs retain the freedom of classic boxer shorts.
To decide whether this is what you are looking for, it helps to look beyond the name and understand the construction.
Support, padding and compression: three different things
Internal support provides a place for the front area to rest. Padding adds a layer of material to create volume. Compression applies pressure to the body. Having support does not automatically mean having padding or compression.
Boxer↑Up has built-in support, contains no padding and is not designed to create a compression effect. Hold-Up is the name of this internal feature.
Where is Hold-Up?
The support is integrated into the front of the boxers. It is not a lining that wraps around the legs. Outside, the garment retains the elegant look of classic boxer shorts; inside, cotton provides discreet support at the front.

That separation of functions is what defines Boxer↑Up: support at the front and freedom for the legs. If you like classic boxer shorts but want front support, this is the feature to consider.
Why are the outer and inner fabrics different?
Each material has its own role.
- Outer fabric: 72% cotton, 25% polyamide and 3% elastane. A soft stretch shirting fabric designed to move with you.
- Internal Hold-Up: 100% cotton, only at the front.
The fabric can feel silky, but it contains no silk. Boxer↑Up is made in Italy.
What does it look like when worn?
Boxer↑Up keeps the classic boxer silhouette. Support is on the inside, with no external padding. Flat seams and the absence of irritating internal labels complete a construction designed for everyday comfort.

How to decide whether they suit you
- Your preferred fit: do you want freedom around the legs or a close fit along the whole leg?
- The function you need: front support differs from padding or compression.
- Your size: check the Boxer↑Up size guide and compare measurements before ordering.
