Superb trousers

I bought these trousers on the spur of the moment and I am so pleased that I did. Well made, robust and versatile. In the first week I wore them on a cliff path walk, to put on after a mornings kayaking, to cycle into town and to visit the local pub and at no time did they feel out of place. It is no exaggeration to say that they are quite possible the most comfortable trousers I have ever worn. 3RD Rock, wasn't a company that I had heard of before but if all their products are as good as these I will certainly be order some other items.

Great but green!

I really like these trousers a lot. They are fantastic to climb in, without restricting flexibility and movement. I was a bit surprised by the colour as I was expecting them to be blue, but they are definitely green. I know that colour can vary between screens, but even the name ‘Night’ suggests blue. However I still really enjoy wearing them and they fit really well. Would have given 3.5 but I can’t so I docked 2 stars as they weren’t as expected because I wanted a pair of blue trousers.

Good Jeans!

very comfortable, soft touch but they seems very resistant. I am very please with the purchase. I will repeat!
