With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

What are the Motus AR Bottoms?

The Motus bottoms are warm, quick-drying, high-wicking, comfortable baselayer leggings designed for virtually all mountain activities, ranging from trail running to scrambling and everything in between. 

What are they made of?

They're made using Phasic AR II, an ultra-breathable, high-wicking polyester with a durable anti-odour coating. This fabric actively wicks away sweat when you work hard, keeping you warm and comfortable, while the anti-odour coating means you can wear them for multi-day trips without offending your campmates. As well as all the techy stuff, they feel great next to skin and can be worn all day without a second thought. 

What are the Motus' features?

They feature a low-profile merrow stitch construction for optimum comfort and strength, plus Arc'teryx's brilliant articulated patterning to enhance freedom of movement. 

How do they fit?

They feature a trim fit for optimum moisture-wicking performance and an ankle-length to prevent them from getting in the way of your footwear. A gusseted crotch, articulated patterning and a naturally stretchy fabric means you're never restricted.
