• Fit: Carrot Cut, loose at the crotch & fitted at the calf
• Fabric: EcoMORPH 4 way stretch denim. 86% Organic Cotton, 11% Polyester, 3% Elastane
• Suitable for: Climbing, Lifestyle, Cooler Temperatures

FITZ jeans are really confortable. The cut is a bit wide, but if you need to dress formal for work it work perfectly with a shirt. I've been surprised that I can do stretching with those pants on, without feeling anything :) total freedom of movement. Now I have no more excuses for skipping the stretching sesh...

• Fit: Loose / traditional climbing pant style
• Fabric: 94% Organic Cotton, 6% Elastane
• Suitable for: Climbing, Martial Arts, Yoga, Warmer Temperatures

I bought these for Tai Chi instead of traditional overly baggy heavy trousers. They are great! Their lightness yet durability and the all important flexibility makes these a good all rounder. All martial art trousers don't have pockets where these do, they are great for everyday casual use and eco friendly aspect is of great importance to me. I wasn't sure their flexibility would be adequate but they are surprisingly quite brilliant. I actually have been looking for trousers like this for years!

• Fit: Tapered, fit to waist.
• Fabric: 98% Organic Cotton, 2% Elastane
• Suitable for: Climbing, Lifestyle, Warm & Cool Temperatures

Mercury Climbing Jeans - From Another Planet!

To put simply. Excellent! The jeans are incredibly comfortable and the range of motion I have when wearing them has been more than capable of dealing with all my bouldering adventures. Minus the chalk marks I leave on them they are also great as a casual wear item, whether chilling at home or out at a pub with friends. I would thoroughly recommend these jeans!

• Fit: Tailored, slim leg.
• Fabric: 97.5% Organic Cotton, 2.5% Elastane mix
• Suitable for: Climbing, Lifestyle, Warm & Cool Temperatures

I am delighted with my purchase of Ramblas. The fit is great, the built in belt adjustment works well, they have a quality finish and the material feels so comfortable and light no matter what activity you do.

• Fit: Slim Jogger/Yoga Pant. Flexible fit waistband & ankle cuffs.
• Fabric: 94% Organic Cotton, 6% Elastane
• Suitable for: Yoga, Climbing, Lifestyle, Loungewear, Warm & Cool Temperatures

Best and most comfortable trousers

These trousers fit perfectly and are incredibly comfortable. The material and design ensure great movement and no restriction. I love the higher waist band too, a lot of thought has gone into these trousers.

• Fit: Mom Fit. High waisted.
• Fabric: EcoMORPH 4 way stretch denim. 86% Organic Cotton, 11% Polyester, 3% Elastane
• Suitable for: Climbing, Lifestyle, Cooler Temperatures

Best pair of jeans I own

I love these jeans. I bought them for climbing but I’ve lived in them since they arrived. They are so comfortable and have amazing stretch for climbing. They are also completely on trend at the minute and work well as an everyday jean. Also it’s nice to find a pair of jeans for women that are not super low cut and also have pockets that are functional. 100% recommend :)

• Fit: High rise, tapered leg.
• Fabric: 94% Organic Cotton, 6% Elastane
• Suitable for: Climbing, Lifestyle, Cooler Temperatures

Feels bespoke!

Super happy with these trousers, I’m a size 12/14 and I don’t often find trousers that fit well, but I love the flexibility and high waist fit, it feels like they’re made for me! Highly recommend.

• Fit: High rise, tapered leg. Fit to hips.
• Fabric: 98% Organic Cotton, 2% Elastane
• Suitable for: Climbing, Lifestyle, Cooler Temperatures

Love love love!

Absolutely delighted with my Margo trousers!! The design pattern around the waist and pockets is very stylish, and the colour is awesome. I'm quite tall (5'9 with long legs) and find these a better fit than many other ladies climbing trousers. The elasticated ankle cuffs help make the length seem right, and also let you see your feet well when climbing! They are comfy and flexible, and the drawstring waist means you can make them fit perfectly to your own shape. Love!

Lightweight and comfy!

I absolutely love these trousers, they're amazingly comfy and very flattering. They aren't restrictive when climbing either on my home wall, outdoor bouldering or trad. Great for some summer climbing!
