How do I preserve the treatment on my anti-mosquito garment?

Machine wash at 30°C on a normal cycle. To preserve the effectiveness and longevity of the anti-mosquito treatment, do not use bleach or dry cleaning, and avoid ironing at too high a temperature.

Is this trouser suitable for hiking in intense heat?

Yes, this model is made from an ultra-lightweight, highly breathable fabric. It wicks moisture away rapidly to keep you dry and cool, even during intense effort in the height of summer.

Are the leg zips uncomfortable when walking?

Not at all. The zips on our convertible trousers are covered by a protective flap on both the inside and outside. You won't feel any rubbing on your thigh during your hiking.

What are the delivery times for this product?

If you place your order before 1 pm (excluding weekends), it will be dispatched the same day. Allow 2 to 4 working days for home delivery or collection point delivery within mainland France.

Can I return the item if the size doesn't fit?

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.

Who did we design it for?

For the travellers and trekkers heading to tropical or temperate regions.

On varied terrain, you need trousers that protect against mosquitoes and sun, are functional and remain comfortable.

How should you wear it?

Worn as the base layer directly against the skin. Remove the legs via the zip to convert it into shorts without taking your shoes off.

What makes the difference?

Its mosquito-repellent treatment and 8 pockets including 2 hidden ones in a shorter length for men under 170 cm - the 2-in-1 travel that anticipates every situation.

Hiking

The travel trousers that transform in one move

Clammy heat, persistent mosquitoes, aggressive UV. On trek or travelling long-distance, conditions change fast between the morning trail and the afternoon town. One bottom must cover both.

The Katmandou 3 was designed for long stages in warm climates. It repels biting insects, provides UV protection and dries quickly after exertion. The legs zip off from the sides, without removing your shoes. Eight pockets, including two hidden ones, keep documents and valuables out of reach.

Because travelling lightweight means carrying just one piece that does the work of two.

In summary This content is written by AI

Customers are won over by this pair of trousers’ comfort, light weight and practicality. They appreciate its fitted cut, spacious pockets and thoughtful details, such as the glasses wipe and side zips. Several also praise the quality of the finishing and the excellent value for money; one customer found it cool and light in the mountains, while another has already ordered a second pair. As the leg length and waist can vary depending on body shape, check the size guide carefully before choosing.

Been after a pair of trekking trousers for use during the Summer for a while and saw these were on offer. I'm 5ft 11 inches (1.80m) and 32 inches waist, however sizing can sometimes still be an issue for me, yet these size M are absolutely perfect in waist measurement and leg length. Made from good quality material and match specification description. No hesitation to offer recommendation and add another great product from CimAlp to those I already possess.

To be honest I haven’t received the product yet. I did receive an email from UPS to say it would be delivered to the drop off point on Friday last. I went to collect it but it was not there. I am still waiting for an update from ups

Very practical trousers for travel with a hidden pocket to keep your passport safe. One of the two leg pockets is also secured with a zip in addition to Velcro. Plenty of advantages to choosing these trousers for travel.
