Years of field testing and feedback from ABC's athletes have convinced them that their etriers are among the toughest and most comfortable on the planet. Reinforced triple sewn steps stay open, even in windy conditions, and provide unparalleled stability. Top steps are perfectly seated for high, out of reach placements that demand levering out. On his recent ascent of Mount Poi in Kenya, Paul Piana said, "ABC Etriers are better than any other etrier I've ever used." Each 7-Step Etrier weighs 380 grams.
