Water repellent properties info

An excellent stretch trek pant which can be used continuously for many days without changing. The quality of fabric is excellent. Very comfortable to wear under all conditions of trek. Real quick dry. I would recommend everyone to have at least one of these, and you can praise me later for recommending it.

Really nice trousers but I found them too tight around your thighs.

Worth the Extra
Used for 3 to 6 months
I could have got the Forclaz 500 stretch trousers for hiking, and saved 20 quid. However I was drawn to these for some reason. So glad I did though.
Pockets are well situated for GPS, wrappers off my snack bars etc. while not letting things dig into my legs - probably the stretch helps, they are VERY stretchy.
They are a slim fit, and to me this makes them warmer - no draughts - plus less mud working its way up from the ankles as they rub less on each others legs.
I tighten the ankle cord, and clip the bottom hook tight down my laces and as mentioned re mud, quite often it obviates the need for gaiters - unless it's very muddy and wet.
Quite windproof, not often I've put on long johns as it gets colder. They take a while to wet out in the rain, dry very quick and are comfortable even when wet - so I resist over trousers for longer than I normally would. I'm in my 50's and walked for a loooong time. These are the best walking trousers I've ever had.
Used for 7 to 12 months
Decathlon! Please sort the belt out.

These pants, when treated well, were sopme of the comfiest walking trousers I have tried.

Being young, I favour the slim fit of these and they saw me comfortable for many walks...until the belt buckle broke.

Because of the style of the belt and the loops it truly rendered the trousers useless. Which is a shame, because I reckon if the belt was improved they'd be only trousers I'd by for all my exploring.

Please sort this out for the next incarnation of these!
Fantastic trousers
Used for 3 to 6 months
I wear these daily for work, I find all of the pockets to be of good size. the fabric is very comfortable, I recently wore them trekking in the Himalayas for 3 weeks straight and over 5000m numerous times. they were great. they are skin tight pretty much!
