Stretchy waterproof smock with a softshell feel – built for mountain running

The OMM Kamleika Smock is an icon among mountain runners. Now in its 6th generation , it offers the same legendary comfort and freedom of movement that has made it a favorite since 2005 – but with a clearer focus on sustainability. The latest version is updated with a PFAS-free membrane and PFC-free DWR treatment , reducing environmental impact without compromising performance in tough weather.

Kamleika is known for feeling like a softshell against your skin , while being fully waterproof, windproof and taped . The result is a protective layer that doesn't rustle, doesn't feel stiff and really follows your body - even when you're running steep climbs or technical descents.

Size chart

The measurements refer to body measurements, not the garment measurements.

How is the OMM Kamleika Smock sized?

Kamleika Smock has a Fitted , body-hugging fit. The four-way stretch material provides good freedom of movement, but the garment should still have room for the layers you plan to wear underneath.

Normally, choose a size according to your chest measurement if the smock is to be worn over a thin base layer or a light mid-layer.

Choose the larger size if you:

• is close to the upper limit of the size chart
• have broad shoulders or a more powerful upper body
• want to use a thicker mid layer
• prefer a less body-hugging fit
• want the garment to be easier to pull over the head and shoulders

Since the Kamleika Smock is a pullover model with a half-zip, a slightly roomier size can also make it easier to put on and take off.

Size guide for women

The model uses OMM men's/unisex measurements. Therefore, choose according to your actual chest measurement and not just your usual women's size. For many women, a size smaller than the usual OMM women's size corresponds to approximately the same chest measurement, but always check the chart.

How do you measure?

Chest: Measure around the widest part of your chest. Hold the tape measure horizontally and let it lie close to your body without tension.

Waist: Measure around the natural waist, usually where the torso is at its narrowest.

Body length: Stand barefoot with a straight posture and measure from the floor to the highest point of your head.

Please measure with the base layer or thin midlayer that you normally intend to wear under the smock.

Check the fit

The correct size should:

• sit close to the body without tightening the chest, shoulders or back
• provide full freedom of movement when raising your arms above your head
• let the sleeves cover the wrists without the thumb grips tightening
• keeping your back covered when running or leaning forward
• make room for planned layers without compressing them
• be possible to pull on and off without excessive effort
• let the hood follow the movements of the head without pulling on the shoulders

If you are between two sizes, we recommend the larger size for more storage space and easier on and off.
