Who did we design it for?

Built for trail runners who put reliability above all else.

A short built to handle long distances, technical trails, and whatever the terrain throws at you. Designed for ultra-trails and demanding outings — where your kit needs to last as long as you do.

For those who prioritise durability and support chasing minimal weight.

How to wear it?

Worn directly against the skin, with or without an additional base layer to reduce friction.

Fits true to size — we recommend your usual size.

What makes it different?

Its reinforced fabric, thicker than a standard trail short, withstands friction and contact with the terrain over time. Its 6 ultra-accessible pockets, including 2 zipped ones, keep gels, phone and flask close to the body, without bouncing. Its integrated stretch mesh liner reduces chafing on the inner thighs.

Trail running

Distance puts everything to the test. The Aoste holds.

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.

The Aoste is built to last. It resists friction, withstands repeated contact with the terrain and maintains its support even at the end of an effort. Its flat seams reduce irritation over time.

The waistband keeps your nutrition close to your body, with no bouncing. Everything within reach, no pack needed.

On long distances, reliability comes before everything else.

In summary This content is written by AI

CIMALP's AOSTE 3 H shorts are highly praised for their exceptional comfort and technical features. Users highlight their lightweight nature, quick-drying ability, and practical design with multiple pockets. Most reviews are very positive, mentioning that the shorts stay in place even during long runs. However, a few users note that the phone pocket can be too loose and that the flask storage can be challenging while running.

Tested on the full Échappée Belle race, in rain and sunshine. Soaked at the start of the trail, the shorts dried quickly as soon as the rain stopped. They offer light support around the thighs, which feels comfortable. The thigh pocket is perfect for my phone: it stayed there for the whole 150 km, and it’s handy for taking it out and snapping photos. The large pocket at the back can hold a 600 ml flask without any problem. No chafing at all (I wear underwear). Once properly fitted, they don’t move and you forget you’re wearing them. Very good product, I adopted it after my very first try.

Extremely comfortable. Good hold at the waist. Useful multi-pocket belt but, for me, for small light items: cereal bars, gels. The phone bounces around a bit too much for my taste, so I put it in my vest instead. But a very good product overall.

Great product. Very comfortable, super absorbent and dries really fast. The pockets are useful but be careful what you put in them (stick to the lightest items possible since the inside of the pockets is flexible like the rest and could affect overall comfort during use). I recommend it 200% (they've definitely replaced my old hiking shorts).
