Comfiest shorts ever

These are the most comfy denim shorts I’ve ever owned and they look fab. They stretch in all directions without losing shape - just amazing. I’d recommend these to anyone who wants a fabulous pair of shorts that you can do anything in, dog walking, chasing the kids around, overeating at a barbecue. Everyone should own a pair even if the only thing you will ever climb is stairs (like me).

Love these shorts!

I absolutely love these for climbing indoor and outdoors. Fab fit, feel secure that nothing is going to ride down or legs ride up! Extremely comfortable and move really well with the body. I'm so glad I got them :)

Women's Thor Shorts

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!

Women's Reese Dungarees Shorts

  • Fit: Close fitting, customisable fit.
  • Fabric: 94% Organic Cotton, 6% Elastane
  • Suitable for: Climbing, Lifestyle, Hiking

Dungarees. For climbing. What's not to love?!

I wear dungarees all the time, long ones, short ones, baggy, tight. But they've never felt quite right for climbing, they either restricted my movement or flapped around too much. So I obviously had to try the Reese dungaree shorts. And they did not disappoint. They have pockets! That is so rare for women's garments.

The fit is great (I had to downsize a bit but once I got the right size they were perfect). The material is super stretchy for those high feet or wide splits moves. Also, they have pockets! I love the print and have already had a bunch of compliments. The little carabiners are very cute and obviously just add to the climbing vibe. You know your dungas mean business when they need to be clipped like a quickdraw. Anyway, absolutely love them. Did I mention they have pockets?


So your much loved item couldn't keep up with you, but you're not ready to give up on it just yet. After all, you've been through a lot together.

Good on you, high five! Welcome to the repair club.
