The Mach Express excels in each of these areas. The Nano 22 on the gear end situates perfectly on any kind of pro from wires to cam slings to bolt hangers and pitons. Their low profile also takes up less space on gear loops than traditional carabiners and they fish in and out of cracks, chain links and other tight spaces with ease. The Photon Wire is the lightest full-size carabiner on the market making it the optimal choice for the rope end. The 10 mm x 60 cm Dyneema® slings are light, strong and thin making them the perfect choice for long routes. The unique properties of Dyneema® also make them particularly well-suited for wet conditions common with alpine terrain.

A good draw for long routes should be:

Light – they are being carried a long way
Compact – sometimes you need to carry a lot of them
Versatile – you never know what big routes will throw at you
Functional – easy to use in any situation
