One harness, one device, one carabiner — everything needed to get on the wall today
What Our Gearhead® Experts Are Saying:
"This package is what I'd hand someone on their first day at the crag or point a gym regular toward when they're ready to start climbing outside. The 4 Slide fits over layers without a fight, the Smart 2.0 is forgiving enough to build good lowering habits, and the carabiner is purpose-built to work with the device. Everything in this bundle is actually designed to work together, which matters more than people realize when they're learning."
Getting to the base of your first outdoor route with your own gear changes something. The Mammut 4 Slide Harness Package removes the guesswork from that first purchase by pairing a do-it-all harness with a belay device and carabiner that are purpose-matched from the start.
The 4 Slide's four Slide-Bloc buckles make dialing in fit fast, whether we're pulling it on over a softshell at a cold crag or trimming it down for a hot sport-climbing day. Wide padding zones keep us comfortable through long belays and hanging rests without creating pressure points that build into a distraction. The Smart 2.0 adds assisted braking to the system so the mechanics of lowering stay controlled even on long days when focus starts to slip, and the HMS carabiner's safety gate keeps it locked into position and loading correctly every time we clip in.
