FAQs

Are these trousers suitable for cold weather?

No, the Rab Momentum Trousers are specifically designed for warm conditions due to their lightweight and breathable materials. They are not insulated for cold weather.

How much storage space do these trousers offer?

These trousers feature two open hand pockets with mesh venting bags and one YKK zipped rear pocket. They are designed with a minimalist approach to storage.

What type of activities are these trousers best for?

They are ideal for high-output activities in warm weather, such as thru-hiking, fastpacking, summer trekking, and approaches where mobility and breathability are key.

How do I ensure the best fit?

The trousers have a pull-on elasticated waistband with a drawcord and cleat closure for adjustment. Refer to the sizing chart and adjust the waistband for a snug but comfortable fit.

Can I wear a baselayer underneath?

Yes, you can wear a lightweight baselayer underneath for added comfort or warmth in cooler conditions. However, the trousers are primarily designed to be worn alone in warm weather to maximize breathability.

What is the main benefit of the articulated knees?

The articulated knees are designed to provide enhanced flexibility and freedom of movement, allowing for easier climbing, stepping over obstacles, and general agility on uneven terrain.

Troubleshooting

Trousers feel restrictive during high steps.

Ensure the waistband is properly adjusted and not too tight. The articulated knees and gusset are designed for mobility, so check that they are aligned correctly with your leg.

Fabric feels clammy or less breathable.

This can occur if the fabric's moisture-wicking properties are compromised. Ensure you are not using fabric softeners during washing. Wash with a technical fabric cleaner if build-up is suspected.

Waistband closure feels insecure.

Tighten the drawcord and ensure the cleat closure is engaged correctly. If the drawcord is frayed or damaged, consider replacing it.

Zipped pocket is difficult to use.

Check for any debris caught in the YKK zipper. Lubricate the zipper with a small amount of paraffin wax or a specialized zipper lubricant if it feels stiff.

Pros and Cons

Pros

  • Extremely lightweight and packable.
  • Excellent freedom of movement due to stretch fabric and articulation.
  • Highly breathable, keeping the wearer comfortable in warm weather.
  • Streamlined design minimizes drag and bulk.
  • Moisture-wicking properties help manage sweat.

Cons

  • Limited pocket capacity (two hand pockets, one rear zip pocket).
  • Pull-on design might not appeal to everyone.
  • May not offer sufficient durability for rugged, off-trail scrambling.
  • Minimalist features might lack utility for some users.
  • Not designed for cold-weather protection.

Setup, Compatibility & Care

Setup:

These trousers feature a simple pull-on design. Ensure the elasticated waistband with its drawcord and cleat closure is adjusted for a secure, comfortable fit before activity.

Compatibility:

Designed primarily as outdoor activewear. They are compatible with most hiking boots and approach shoes. The minimalist design pairs well with lightweight, breathable mid-layers for varied conditions.

Care:

  • Machine wash cold with similar colors.
  • Use a mild detergent.
  • Do not bleach.
  • Tumble dry low or hang dry.
  • Avoid fabric softeners, as they can impede moisture-wicking properties.
  • Cool iron if necessary, avoiding printed logos.
