Trouser Design Consideration

I had earlier suggested that TROUSER pocket sizes must be increased ro accommodate most smart phones 5 1/2" sizes today. I am confident you have passed on thr message to your design team. Second point, Indian currency notes are bigger in size than in most countries, so our purses are bigger, therefore wer struggle to zip close/ open the pockets. So, I suggest the TROUSER and backpack pockets size must be accordingly redesigned. Thank you.

Trousers Ideal for Wear in Thailand!

These are the ideal hiking trousers to wear in Thailand. If the weather is too hot and humid, the lower part of the trousers zip-off to become hiking shorts. The material is breathable, water-resistant and will not mildew. They can be hand or machine-washed (gentle cycle) and dry rapidly, much faster than cotton. It can be packed tightly into a suitcase or backpack with very little wrinkling. The material is flexible enough to use as bicycle shorts with the advantage of having pockets.

OK product to me

May be its my fault, purchased this as a day to day trousers, rather than specifically for hiking. To me the pockets is hardly usable, backpack or a bag is a must as a company to these trousers.

Good value

Excellent trousers with well designed zip-off legs. Hip pockets are a bit small & the thigh one could be bigger too. Too long in the leg for this shorter-than-average Scot! But, overall, really good value for money.

I love these trousers, very comfortable and easy to clean. The fabric is stretchable that adds to your mobility. Very versatile. You have an option to make shorts. Another thing I love about this is the free belt. I also got this with a very special discount.
