SH530 extra warm trousers

Excellent trousers very warm but ventilation zips work well. After reading reviews ordered size above normal and they fit perfectly

These are warm

I used these trousers for a winter climb in the Cairngorms (under a pair of waterproof trousers - it was full on Cairngorm conditions) and they were comfortably warm. The stretch was good for making high steps and the built-in gaiters didn't ride up. It would be worth while trying these on before you buy them - they are quite a close ('athletic', as they say), so might not fit every body-shape. The sizing is also less than accurate - I usually take a UK 32" waist, but I needed a EU medium / French 42, which the Decathlon size chart says is a UK 34 - it definitely isn't.

Brilliant trousers , unusual sizing !!

Buy the size larger than normal !!! If you are 33inch waist buy the size 36inch !!! Otherwise these are really lovely to wear , warm without restrictions of movement .. I get the feeling I am in a comfortable bed when I wear them . They appear sturdy and Weatherproof beyond normal . Possibly my all time favorites !!! However the snow gaitors do not appear as sturdy as typical gaitors , so pack both .

Super warm and comfortable for Ice climbing

Got these today, tried on Fr44 which is meant to be 34W 34L but were to tight, so went next size up Fr 46 and fit perfectly, so get the next size up that you are and you'll be fine, I've tried these with my La Sportive Cube GTX boots and the hidden gaiters inside the trousers fit perfectly on my boots , can't wait to test them out in winter ice climbing...

Buen pantalón que cumple su cometido

Pantalón cálido, para actividades en invierno básicamente. Lo he utilizado para subir a cumbres de 3000 metros en el pirineo con temperaturas bajas y viento y el resultado ha sido más que satisfactorio, piernas calientes sin mallas interiores, y con un resultado más que óptimo en nieve. Es un pantalón que queda ceñido, "marcando" para entendernos, al que le guste ir más "ancho" u holgado no le gustará. Pese a ello tiene cierto grado de elasticidad y se amolda bien a diferentes tipos de posturas. Si Bien no va con tirantes, la parte lumbar es de caña alta, por lo que tenemos la parte baja de la espalda siempre cubierta.

Muy buen pantalón calidad-precio

Muy buen pantalón, no pasas frío lo he probado - 4 grados y perfecto y las cremalleras laterales para ventilar son un acierto, polaina interior, solo pondría una pega o posible mejora a mi entender llevar como los pantalones de nieve tirantes xq son cómodos y flexibles pero se me acaban bajando y tengo q estar subiendo melós y la talla es la correcta, pero calid- precio bueno

Bueno, económico y práctico

Ayer probé estos pantalones andando más de 6 horas por nieve, gran acierto el llevar las polainas ya incluidas y con los refuerzos en los bajos, elásticos y cómodos, repelentes al agua y nieve, bastante calientes gracias a que en su interior el material es como forro polar, en los laterales lleva unas aperturas con cremallera para ventilar en caso de algo de calor de más, como pega los bolsillos un pelin cortos y el ajuste de la cintura, es una goma con velcros yo la llevaba a tope y se me caían un poco, pero aún así los recomiendo, una buena compra

Can i be sure that my pants are warm enough for my winter hikes?

The inside of your pants is brushed – a tried and tested method for retaining heat. The principle is simple: the component weave is structured to add volume to trap air, naturally insulating. It is exactly the same principle as animal fur or feathers.

Good ventilation for optimal thermal comfort.

Thermal comfort is a balance between the warmth of the garment and its ability to let the body breathe. If damp accumulates, you will feel the cold during less active stages (breaks, downhill). We have designed these pants with intense use in mind, integrating a ventilation system with side zippers on the thighs in micro-perforated fabric. Good balance between heat / ventilation for optimal thermal comfort.

Comfortable and practical snow hiking pants.

With their close fit and stretch component, your pants encourage freedom of movement, essential when walking in the snow. The zipped pockets secure everything you need to hand (tissues, lip balm, keys, etc).

What is water repellency and how can you maintain it?

The water repellency of a fabric is its ability to let the water slide off its surface, without absorbing it. In this way, the fabric does not soak up water and therefore remains lightweight, breathable and warm. Water repellency is obtained by a treatment applied on the outer surface of the fabric. This treatment needs to be renewed during the lifetime of the garment (we recommend each wash). Products (sprays and liquids) are available in our stores.

How do my pants protect me from outdoor conditions?

In the winter, you need to be protected both from the damp (snow, rain) and wind, as the latter cools the body down a lot, both when exercising and resting. We designed your pants with a windproof and water-repellent outer fabric, to cope with all winter conditions. We have also added waterproof inserts on the buttocks and on the ankles. Gaiters with a hook for the laces to protect you from snow ingress.

The ideal outfit for hikes in cold weather!

We have designed these pants as part of the ideal outfit for hiking off the beaten tracks: the SH500 outfit. With your SH520 pants, SH500 fleece, SH520 boots and SH500 snowshoes, you can enjoy hiking on snow in all weathers. Go light and well equipped!

How should i dress when hiking on the snow?

To dress correctly in the winter, no matter what your activity is, we recommend that you apply the 3 layer principle: layer 1: The technical base layer will enable damp to be wicked away to keep skin dry. layer 2: The second layer (fleece, pullover) provides warmth and wicks away the damp. layer 3: The jacket protects you from outdoor conditions: rain, snow, wind. The outfit must be breathable to wick away damp.

Will my pants withstand regular use over a long period?

To check the durability of our products, we carry out tests on the components selected: resistance to rubbing and abrasion, colorfastness, resistance to repeated washing. All these tests have been carried out on the component used for these pants.

How does my product warranty work?

This product is guaranteed for 2 years from the date shown on the receipt. A product covered by the warranty will be exchanged free of charge. The warranty covers product defects, excluding those resulting from normal wear and tear and improper use.

What is the environmental impact of the products and how can i compare them?

Product testing

We carry out 2 types of thermal tests: - a pants test material. - a test on a thermal mannequin in a thermal chamber. We reproduce temperatures, wind (3 mph) and damp that you will encounter during the mountains on a 3 mph walk. These tests enable us to confirm our design choices and adapt the thermal insulation where you need it most.

Storage instructions

Store in a dry, dark space. We recommend that you avoid harsh chemicals such as bleach, which can affect the thermal insulation of this clothing.
