Our Verdict

The Moon Climbing Hubble X Slim Fit Jeans are a fantastic trouser. They deliver functionality and durability. When you are wearing them, they do not feel like a typical jean and allow a full range of movement. They are also good looking enough to wear around town or to go and grab a drink with mates after the climbing session is over.

We really like the fact that they are understated. There are no massive branding marks, although if you turn the jeans up, the ‘Moon’ print is seen on the inside of the pant leg. It is a great little quirky design. Overall, these trousers deliver in terms of price and performance. A good cut, they can be worn both inside and outside.

We had a full range of movement from these trousers, this is owing largely to the stretch insert. The pants also come in two colour styles. Even so, the colours are an acquired taste, and you can really tell they are climbing pants! The pockets are very big, and there is also a handy pocket for a bouldering brush. Overall, they are top trousers for bouldering.

Our Verdict

Coming in three different colours, the Arc’teryx Kestros Pant is as stylish as they come. They are very light and very stretchy. We are not sure how durable they will be, but they stood up to our testing. There is a tapered leg, and this could annoy some.

Another unique feature is the zipped back pockets. No other pant features something like that and means if you need to stash some coins or similar, you can do. Overall, these bouldering trousers are the perfect crossover. You can easily wear them around town, or at the wall.

An up and coming trouser. Ocun knows what to offer at a good price. They are very robust and look the part. There are plenty of pockets for those of you who like to have as many as possible! The dedicate brush holder is also a nice touch. What’s more, the integrated belt with buckle is really helpful to get the perfect fit.

They are a bit on the heavier side, at 660g for the ‘M’ size, but that is what you get for the price. The Ocun brand is up and coming in Europe and we are very happy with their products. The trousers fit well and allow the full range of movement. If you are on a budget these are the ones for you!

How to Choose Bouldering Trousers: What We Looked Out For

There are a number of things you need to consider when choosing your preferred bouldering trousers. Namely, the fit, comfort, and material used. You also need to consider your use of the pant. Will you use them inside, outside? Do you want to wear them for things other than bouldering? Such questions must be factored into your decision. Only you can know for sure.

The Fit of the Trouser

For us, freedom of movement is an integral factor when it comes to analysing bouldering trousers. They definitely shouldn’t be too tight. An adjustable waist will also allow you to find the perfect fit in this regard. Furthermore, if the leg has elastic or drawstring to keep it out of the way of your shoe then you are on to a winner.

Stretchiness and Durability – Material Used

Another very important factor is the stretchiness of the material used. Your trousers should be stretchy enough so you can move around unimpeded. Nevertheless, this should not come at the cost of durability. The perfect pant will combine the two effectively. The ones we listed here do.

Pockets and Extra Features

Although this didn’t really affect the overall ranking too much, having extra little things on your pants could really sway your decision. If you want pockets, then make sure you choose some pants with them! Things like brush holders, a loop for a chalk bag, or even an integrated belt can also be beneficial.

Comfort and Style

You have to make sure you enjoy wearing your trousers. If the style is important, and you want to match with your bouldering shoes, then things like colour and how the pants are tapered will affect your choice.

What’s more, they should be breathable and the material should not rub on your legs. At the end of the day, you will be wearing them a lot, so it should be a pleasant experience.

Overall the Best Bouldering Trousers Need to Fit You!

Just like any other type of bouldering gear, the trousers need to fit you and your body type. Yes, we have tested these thoroughly, but you really need to try them for yourself to get a feel for them. Everyone is different, what works for us may not for you.

We’d recommend giving a couple of pairs a chance and seeing which one fits best. Then you will be crushing in no time! We have also provided tips on what to wear bouldering to complete your outfit!
