What Our Gearhead(R) Experts Are Saying:"I use the Stonehauler 125L Duffel Bag for expedition climbing trips where I need to haul a full rack, ropes, and camp gear in a single bag that can take serious abuse. The HaulLoop carry system rated to 2kN is not a marketing claim; it is the kind of confidence you need when your bag is getting dragged across talus or clipped to a haul line."The drive to the range is long, and the gear list even longer, and the Black Diamond Stonehauler 125L Duffel Bag was built to hold every piece of it together without complaint. At 125 liters, this is the largest bag in the StoneHauler lineup, engineered specifically for climbers and alpinists who need to move serious amounts of equipment to serious places. The HaulLoop carry system wraps the entire duffel in a continuous tubular webbing loop tested to 2kN by the same machines that load test carabiners and Camalots, giving you a clip-in point and a carry system that you can trust no matter how the bag ends up moving through the world. The side-to-side padded body construction uses 5mm closed-cell foam to resist puncture and abrasion on rough terrain, while the LockOut Internal Compression System brings order to a fully loaded bag and keeps the shoulder strap carry feeling controlled rather than chaotic. A DirtBag internal storage system handles muddy climbing shoes and chalk bags without contaminating the rest of your kit, and two interior mesh zipper pockets alongside exterior accessories storage keep small essentials organized and reachable. Built from 100% recycled polyester and stashable as a puffy carry for lighter duffel needs, the Stonehauler 125L is as thoughtfully designed as it is relentlessly capable.
