Overview
Four Slide-Bloc buckles let the wearer center the harness on the waist and tune the leg loops for different clothing. A red material woven into the tie-in loop shows through the fabric if the loop is damaged, and cushioning is listed for long sessions.
Easy buckles suit beginners and experts who change layers or share a harness, and the wear indicator adds an inspection aid. The size range is broad, and the listing offers no waist or leg numbers to confirm the fit.
Who it's for
Gym and crag climbers from first-timers to experienced users who want quick adjustment and a damage indicator on the tie-in. Buyers who need exact measurements or standards marks should confirm them with Mammut before purchase.
Pros and cons
- Four buckles adjust quickly
- Tie-in loop shows wear
- Cushioning for long sessions
- Light with medium stretch
- Hand wash only
- Certification marks not shown

- Limited warranty terms unlisted
Performance notes
Waist and leg buckles slide to set the fit, and the cushioned panels spread load so hanging stays comfortable. The woven red material in the loop is meant to show through as the fabric wears, giving an early sign to retire the harness.
