Pre-Order

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!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Move fast, travel light, and cover more ground with the Momentum Pants.

Designed without a gram of excess material, these tapered, multi-activity pants are super light, streamlined, and breathable, ideal for keeping cool on hot days in the mountains. Rab has used a lightweight, stretchy Matrix™ fabric that gives total freedom and leg lift, and expels moisture to preserve that dry, comfortable feel.
