Cut 220g from my standard alpine rack without touching protection count. Sponsors started asking about the gear before they asked about the route.

The violet-on-black rack is the only piece of gear I've ever had strangers compliment at the crag. And it's still lighter than my old Petzl set.

I have a spreadsheet. Every single Crimp piece beats my previous gear by 8–22g. Full double rack is 340g lighter. That's a 500ml water bottle.
