Ultra-lightweight and technical harness for high-performance climbing and mountaineering
The WHISPER® harness is perfect for climbers and mountaineers seeking minimal weight and maximum mobility. Its MATRYX® fabric ensures comfort, durability and compact design. A slim waist belt and leg loops provide freedom of movement, while five gear loops carry all your essentials. Built tough with reinforced tie-in points, it's ready for your most demanding adventures.
So What Is MATRYX® Fabric
MATRYX construction is composed of woven HMPE strands, with special strands interwoven in specific areas. It allows the harness to be exceptionally low-profile, lightweight, and flexible, so the harness moves seamlessly with the climber while being practically unnoticeable when worn.
Description
- Extremely lightweight and compact:
- 170 g in size M
- Ultra-compact, it takes up minimal space in a pack - Optimal freedom of movement:
- Exceptionally slim waistbelt and leg loops provide absolute freedom of movement, making it practically unnoticeable when worn

Comments
What's the difference between this and the Petzl Altitude? (Apart from 20g). I'm struggling to differentiate the two products
Competing with the Blue Ice Addax, light trad harness
The Addax (140-150g) has limitations, gear loops aren't great but relatively cheap £70
Whisper slightly heavier and presumably slightly more room in pack but if the gear loops are good might be a winner, expensive currently £150
Presumably the lower weight is the difference. It's a bigger market now than in the past. There is room for similar but not identical products. It does look a very nice harness, but not cheap!
Only two caritool slots, shame. Looks really nice otherwise.
The altitude has a lot slimmer waist band which (i presume, I haven't compared them) will be far less comfortable. It also had two perfunctory gear loops, that are plenty for skiing but not sufficient for climbing.
