The OMM Kamleika Overmitt are ultralight, waterproof overmitts designed for trail running, mountain running and other endurance activities in harsh weather . They are made from the same advanced Kamleika® material as OMM's iconic jackets and pants, providing exceptional protection from rain, wind and cold , while remaining highly flexible and comfortable.

Overmitts are intended to act as a flexible layer in a hand system . They can be worn directly against the skin , or over thin gloves or insulating mittens , depending on the temperature and intensity. This allows you to easily adjust warmth and protection without having to change the entire glove solution.

With a water column of 20,000 mm and breathability of 20,000 g/m²/24 h , combined with 37.5™ technology , the Kamleika Overmitt helps keep hands dry and at a stable temperature even at changing pace and inclines. In tests, the material has shown good ability to regulate moisture and heat during transitions between flat runs and climbs.

The super stretch construction provides a great fit without restricting freedom of movement, while the soft and quiet surface eliminates the rustling that can otherwise be annoying during long runs. Weighing around 30 grams per pair , they take up minimal space in your pack and are a popular choice as a mandatory shell garment in ultra races .

The OMM Kamleika Overmitt is a unisex, waterproof and windproof shell mitten with a stretchy fit. It can be worn directly on the hand or over a thin glove or insulating mitten. As it does not have its own insulation, the size should be chosen based on the layers you plan to wear underneath.

Size chart

The width is a product measurement taken when the mitten is lying flat.
* The length is measured from the cuff to the fingertip of the mitten. The measurements are approximate.

How is the Kamleika Overmitt sized?

The Kamleika Overmitt has a body-hugging yet very stretchy fit. It is designed as a thin protective outer layer and can be worn alone or over other gloves or mittens.

Keep in mind that an overmuff that is too small can compress the insulation in the inner mitten. This limits mobility and can also reduce warmth.

Our size recommendation

• Directly against the hand or over a thin liner: Choose the smaller size if you are right between two sizes and want a close, flexible fit.
• Over a regular running glove: Choose the size that allows room for the glove without the material being tight over the knuckles.
• Over a thick or insulating mitten: Choose the larger size if you are between two sizes.
• If you prioritize mobility and dexterity: Avoid unnecessarily large volume around the hand.
• If you prioritize warmth and layers: Leave enough space so that the inner mitten does not compress.

How do you measure?

1. Place the glove or inner mitten you intend to use on a flat surface.
2. Measure the width across the widest part of the palm, not including the thumb.
3. If necessary, measure from cuff to fingertip and compare with the length in the table.
4. Choose a Kamleika Overmitt that is roomier than the layer underneath.

If you are going to wear the overglove directly against your hand, you can instead compare the measurements with a similar mitten that already fits well.

Check the fit

The correct size should:

• allow you to open and close your hand without the material tightening
• give your fingers full freedom of movement
• do not compress an insulating inner glove
• stay seated while you run and move your arms
• provide sufficient overlap between the extended cuff and the jacket sleeve

Remember that the Kamleika Overmitt is a shell mitten and not an insulated winter mitten. In cold conditions, it needs to be combined with a warming glove or inner mitten.
