Petzl Croll S
Lighter and more compact(by about 1/3) than the older versions.
New cam (longer and narrower) for tenacious grip on ropes from 8mm - 11mm. Stainless steel plate reduces friction an improves wear; especially useful for those Pantin users whose technique wears the front plate of the jammer more quickly.
For users who require a larger chest ascender, the CT Evo Chest May be worth a look.
Weight 85g, alloy frame, stainless steel cam and wear plate.
