Fold names describe how a pad closes, but the landing surface depends on the exact construction. Metolius says its angled hinge design eliminates the gutter; Black Diamond lists hinge and Z-fold models, and Organic describes a hybrid-hinge pad. Compare open coverage, seam placement and folded dimensions on each model.
A fold affects how a pad packs and where its panels meet. Compare the landing face and carry format on the exact model.
Compare maker-described folds
| Design example | Maker description | What to compare |
|---|---|---|
| Angled hinge | Metolius Basic Pad and Session II describe angled hinges designed to eliminate the gutter | Open face, seam position and folded dimensions |
| Hinge | Black Diamond Circuit is described as hinge-style | How the face sits on uneven ground and how the pad carries |
| Z-fold | Black Diamond Circuit Z uses a Z-fold design | Panel count, open coverage and packed size |
| Hybrid hinge | Organic Simple Pad uses a hybrid hinge | The exact fold geometry, landing surface and carry features |
These are model-specific examples. A construction label is not a common performance rating; compare the maker’s open and folded specifications.
Use the landing area to decide
Think about the problem’s landing zone, uneven ground and how pads will be positioned together. Then compare fold layout, carry straps and closed size. Our crash pad size and coverage guide explains dimensions and UIAA 161.
Common questions
Do hinged crash pads always have a gap?
No. Metolius says the angled hinge on its Basic and Session II pads is designed to eliminate the gutter. Check the exact model's open surface.
What is a Z-fold crash pad?
It uses a Z-shaped multi-panel fold. Black Diamond describes its Circuit Z as a Z-fold model; compare its open and folded dimensions with your approach and landing.
What does hybrid hinge mean?
It is a maker's construction description, not a uniform size or performance standard. Organic uses the term for its Simple Pad; check that model's dimensions and design.
Does UIAA 161 define a fold style?
UIAA 161 covers crash-pad safety requirements and tests. It does not prescribe a hinge, Z-fold or hybrid construction.
