Awesome Jeans

Very good quality! It is so comfortable to wear for climbing and for chill out as well, thanks to its stretchy charakter.

Mercury Jeans

A great pair of trousers. These are my second pair. I've used them mainly at the wall over the winter and have found them comfortable, a good fit and completely unrestrictive (although it takes a few wears to break them in to maximum stretch, so bear with it). I also use them for general outdoor wear. I would definitely recommend these trousers. I'll be back for the shorts in the spring

Best Jeans I have ever worn!! Awesome product, awesome brand.

I never knew the world could be so comfy! Haven't had a sad day wearing these jeans yet!!
On a more sensible note, these jeans are really nice, don't feel like conventional jeans at all yet they are just as durable.

My special.

Great trouser when you climb.


Love these trousers... less time for climbing these days, but find them really useful for getting in and out of those pesky loft hatches etc whilst at work. Big thumbs up :)
