I recently came into possession of a pair of Solutions. Approximately size 43, good condition, not the newest model. Pictures here. Asking price is $100, but that is not firm.
The Black Diamond Solution harness has no signs of wear. Asking price is $50, but that also isn't firm. Pictures can be provided upon request.
Available for shipping (fees not included in listed prices above), or pickup in the Raleigh, NC area.
