Great outdoor pants..

I’ve purchased these before, easy to wash, easy to dry, not an iron in sight.

Had to return for the bigger size as seemed slightly smaller than the last ones I bought. Otherwise these are a great product

Snug fit round the bum and thighs. Nice length though. Not much space for thermals for the bigger legs.

Versatile trousers

Great for walking and as a casual pair of trousers when taking the hybrid bike for a spin into town to save on the diesel!!!

As described, wish they did them in Grey & Black

Very happy with these, have been using the shorts version for years. Fit is excellent and materials very robust. Pity they don't do them in a grey/black colour combination like the shorts.

Excellent trousers really comfy and the stretch is ideal . True to size on the waist and leg a little snug in the department area but nothing major

excelent product

I'm using one of these almost every day for the last year and a half; absolutely perfect for most walks and hikes early spring to early winter!

Outstanding trousers

These trousers are absolutely fantastic...well made.. Durable and lots of stretch in the material when hiking or scrambling up hills and mountains.,... I have worn these mainly in the summer months but could be used in winter with a base layer underneath.... These trousers are really easily in a par if not better than much higher priced trousers from famous manufacturers....

Great purchase

Comfortable, practical, fantastically stretchy and move with you without restricting movement. Draw chord at ankle is a useful feature.

Additional Product Information


Main fabric

  • 100% Polyamide

Outer fabric

  • 88% Polyamide
  • 12% Spandex


  • 100% Polyester cationic


  • 85% Polyamide
  • 15% Spandex

Hybrid construction

Pants designed with 2 different components: - a durable fabric (7.3 oz/sqm) on areas that need protection from rubbing (buttocks, bottom of the leg at the front). This fabric is slightly stretchy, offering great freedom of movement - and a light and breathable fabric (4.4 oz/sqm) on the rest of the pants.

Water-repellent properties info

These pants have water-repellent inserts (bottom of the legs at the front, buttocks) that enable the water to slide off the surface of the fabric. Please note, this does not mean WATERPROOF. The water-repellent property prevents the pants from getting wet too fast but will not keep you dry under steady rain. For this, we recommend that you wear overpants such as the Trek 500 (ref. 8493660). Water-repellency can be reactivated by tumble drying the pants for 10 min on low temperature.


2 zipped hand pockets 1 zipped left thigh pocket 1 right thigh pocket with flap and 1 internal smartphone compartment. Elasticated tightening system at the bottom of the leg for perfect adjustment of the pants on the shoes. Pants sold with a belt

Sizing information
