Complete your outfit

Who did we design it for?

For trail runners and fast hikers who want durability and a secure fit without extra weight: built for long distances and technical trails.

What storage does it have?

1.5 L of storage: a multi-pocket waistband for a flask, phone, gels and bars, plus a key loop and two zipped pockets.

How does it protect against chafing?

The integrated liner reduces rubbing between the thighs, while flatlock flat seams help minimise chafing.

What makes it different?

Our CIMAFLEX technology: a stretch fabric thicker than that of standard trail shorts. It moves with your stride and resists rubbing and contact with the terrain.

Distance puts everything to the test. These shorts hold up.

On long-distance trail runs, the terrain puts your kit to the test with every stride. Repeated friction, technical ground, the constant risk of a fall. A short that gives way at the wrong moment, and your run is over.

These shorts are built to last. They resist rubbing, withstand repeated contact with the terrain and stay securely in place even towards the end of a long effort. The integrated liner and flat seams help limit chafing over time.

The waistband keeps your fuel close: your flask, gels, bars and phone stay within easy reach.

On long distances, reliability comes before everything else.

In summary This content is written by AI

Customers love this shorts-and-tights combination for its comfort, light weight and many storage pockets, which keep a phone, soft flasks, gels and energy bars close at hand without getting in the way. They wear it for short and long trail runs, a marathon and even ultra distances; several have bought more than one, and some no longer run without it. The integrated tights and lack of chafing on long outings are also praised. Note that some find the pockets less well-fitted than on the previous version, with items moving around; if you carry keys, check that they stay secure.

I have been a long-distance runner for more than 35 years. Over the years, I have searched for the perfect 2-in-1 running shorts and tried almost every brand and model without finding the ideal fit. For me, the CimAlp Aoste running short is the holy grail, and I could not be happier. The inner short fits me perfectly, and there is no chafing. The waistband has the perfect width and elasticity, and there is plenty of storage. Said differently; this is the running short I have been looking for my entire life, and I could not recommend it more highly.

Great shorts. To find a fault the phone pocket in inner tights is too loose.

Very happy with the fit ans design it is exactly what I was looking for. Highly recommend to anyone who needs gels or other bits but doesn't want to carry a vest. The belt fits very large items even my water bottle (250ml) or SamunsungS23 ultra with no issues. Very happy with my purchase

At first glance, I noticed the significant weight, but once you put it on, you don't feel it anymore. The fabric seems very resistant and the drawstring on the waistband is essential for tightening well at the waist and preventing it from moving. The belt with its various laces is good and functional (I use them to attach small items like keys), although I would have preferred it to be a bit higher to better hold gels or flasks. The inner short is very comfortable and soft but not very restrictive. I would have preferred it to be more snug, and in fact it's not suitable for holding a phone while running (it moves too much). Overall, the short is highly recommended.
