Many trekkers and expedition members donate part of their equipment to their Nepali team of guides and porters.
Consider donating your equipment to local guides and porters. It could be a tool you know you won’t use again, but they surely will. Or it can be a small gift so they don’t have to spend their money to buy it.
It could be a jacket, a thermal shirt, a hat, or boots. Imagine the second life you’ll be giving them!
