Quick Summary
The Black Diamond Momentum 4S Climbing Harness in grey, XXS is a climbing harness with adjustable fit features on the waistbelt and leg loops. It uses two pre-threaded Speed buckles on the waistbelt and one on each leg loop for maximum adjustability.
The XXS/S size has 2 gear loops rather than 4 due to size restraints on the waist belt, so this size should be checked carefully if gear carry matters to your setup.

- Gear carry: This size has 2 gear loops, so compare that with the amount of equipment you want to rack.

Who This Product May Suit
This harness is for buyers who need a grey climbing harness in XXS with a highly adjustable waistbelt and leg loop setup. It is also relevant if the reduced 2 gear loop layout on the XXS/S size still meets your climbing carry needs.
When to Consider a Different Option
Choose a different harness if you need more gear loops, a larger size, or a different fit layout. The XXS/S size has 2 gear loops, so it is not the right choice when a fuller rack is important.
Before You Decide
Confirm the XXS fit, check that 2 gear loops are enough for your gear, and make sure the adjustable waistbelt and leg loop setup suits the way you want to wear the harness.
