the OMM Core Boxer

Using the lightest 75g/m2 PrimaLoft® ACTIVE insulation fabric, the Core Boxers are a highly insulating first layer, perfect for tough conditions and cold overnight stays.

PrimaLoft® ACTIVE fabric has high air permeability, allowing a comfortable and stable climate to be maintained, even during high-intensity activities. The woven down is incredibly warm for its weight and with minimal bulk, while the PointZero fly guard acts as a wind and moisture barrier; Core Boxers are well suited to extreme conditions.

Plus, who doesn’t love fluffy pants?

PrimaLoft® ACTIVE blurs the line between wadding insulation and fabric; PrimaLoft® ACTIVE loosely weaves PrimaLoft®’s industry-leading insulation fibers through a fine polyester mesh. The resulting structure is warmer and less than half the weight of a conventional fleece product – down-like performance when dry while still performing when wet.

The OMM Core Boxer is a form-fitting, insulating boxer brief for running, mountain adventures and cold overnight stays. The model features stretch material and a wide elastic waistband for a stable and comfortable fit.

Size chart

The measurements refer to the circumference of the body. If you are between two sizes, you should also take into account how close you want the boxer briefs to fit.

How is the OMM Core Boxer sized?

Core Boxer has a body-hugging and flexible fit . The model is intended to be worn as a first layer and should therefore lie close to the skin without loose material.

The wide waistband sits relatively high and provides support around the waist. The stretch material adapts to the body and allows the boxer briefs to be worn under tights, shell pants or other layers.

Size perception

Core Boxer is generally perceived as normal in size when selected based on waist measurement. An external product test describes the model as well-fitting, comfortable and supportive, especially thanks to the wide and slightly higher waistband.

There are no clear indications that the model is generally small or large in size.

Our size recommendation

Normally choose the size that corresponds to your waist measurement:

• If you are in the middle of a range, you can choose the corresponding size.
• If you are between two sizes, we recommend the larger size for a slightly looser fit.
• Choose the smaller size if you prefer a really close fit and your measurement is still within the range.
• Prioritize that the waistband sits securely without pressing against the stomach.

How to measure your waist

1. Use a soft measuring tape.
2. Measure around the body where the waistband of your boxer briefs normally sits.
3. Keep the measuring tape horizontal and close to your body without pulling it too tight.
4. Measure directly against the skin or over a very thin garment.
5. Compare the measurement with the table above.

Check the fit

Core Boxer fits correctly when:

• the waistband lies stable without rolling or cutting in,
• the fabric follows the body without major folds,
• the material is not tight over the seat or thighs,
• the boxer briefs do not slide down during movement,
• you can run, walk and bend your legs without hindrance,
• The model works comfortably under your other layers.
