Excellent Trousers

Thought I’d give these a go having seen the reviews. Got them today, straight out on a three mile dog walk in a howling gale with new Marino long johns underneath. Very impressed. Beaded a lot of water off and dried very quickly. These will be perfect summer mountain pants. Wish cargo pockets were slightly bigger but left hand one was big enough for pair of seal skins gloves. I own two pairs of Fjallraven trousers and whilst their features are generally better, they are also vastly more expensive.

Great comfort and flexibility

Used this for a Himalayan trek where it rained for a few days, very comfortable. Used two pairs over 10 days, not a single complain.

Poor Quality Fabric

The description says "Tough, hard-wearing fabric," yet it was worn and bobbled after a couple of wears, with stitching coming away. The mesh pockets are uncomfortable with keys in the pockets pretty much rubbing against the skin. I don't trust them for keeping my keys safe either - it seems like they could easily tear. On the plus side, the trousers are comfortable.

Hi, thanks for taking the time to review our Trek500 Men's Mountain Trekking Trousers.


As durability is one of the key aims of Forclaz products, i'm sorry to hear about your negative experience. The fabric on these trousers is normally very durable, it sounds like in this pair there was perhaps a manufacturing defect. I would invite you to return them to your nearest store for an exchange or refund at your convenience.


I shall pass on your feedback with regards to the pockets to the product developers, we are always looking for ways to improve and develop our products and feedback like this really helps us achieve this.

Regards

Great trousers

Quality trousers at a great price

Really good!

I bought these as a last-minute purchase for a trek to Everest base camp. They were really excellent. Good fit, pockets in the right place for wallet, phone etc. I highly recommend them. They do come up small though so I bought 3 different sizes to try on and went bigger. I'm waist 34 but took the XL (normally I'm L). Sizing is somewhat confusing so do try them.

Excellent utilization of pockets while hiking

— comfortable — sweat proof — zipper pockets are amazing — amazing price

Map Pockets

The trousers are excellent quality for the price, they are light in weight and very comfortable. My suggestion to the manufacturer's would be to extend the depth of the leg pockets to be able to accommodate a map in either side, currently they are about 1" inch short.

Hiking trousers

These trousers were excellent. I wore them whilst walking the Camino trail in Spain last week. I covered 183 km in hot weather but they kept me cool and because they are made with stretchy materials they were super comfortable. They walked and dried easily ready for the next day. I'm going back in March to complete more of the trail and will definitely be buying another pair. Great value and perform just as well if not better than other expensive trousers.

Additional Product Information

Composition

Main fabric

  • 100% Polyamide

Outer fabric

  • 88% Polyamide
  • 12% Spandex

Pocket

  • 100% Polyester cationic

Yoke

  • 85% Polyamide

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.

Accessories

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

Straight cut that, thanks to the use of stretch fabric where it is needed, guarantees a high level of comfort when moving. Choose your usual size. Inside leg length of 33" in size 36 (L) Width at the bottom of the Pants: 8.4" in size 36 (L)
