Yes! Climbing is an extremely expensive hobby, mountaineering and ice climbing even more so.
He would have had to have spent thousands if he's doing it at that level.
There is NO way one of his mates has all the gear unless he's a millionnaire and even then, it wouldn't work because you don't usually climb with the same person every single time.
Climbing's a great way to meet people in that respect.
But we spent an absolute bomb on gear alone.
It also wears out, ropes especially, and gear can often enough get damaged or lost, particularly in mountaineering.
Most real climbers who also mountaineer and ice climb have about 5 or 6 different sets of shoes or boots: mountaineering boots (more flexible sole, but plastic), heavy backpacking boots for long approaches with heavy packs in non-winter, ice climbing boots (VERY stiff, inflexible sole), climbing shoes for sport climbing, climbing shoes for long routes, approach shoes for walk-off descents, etc.
Ropes. If you have double ropes you usually buy one and your mate buys another because they cost a load.
I won't even go into ice tools v. mountaineering ice ace, types of crampons, ice screws, or trad v. sport rock climbing gear.
