Basic climbers are allowed to bring 32 kilos each free, after that, they need to pay extra luggage transport charges.
If they want us to arrange their baggage, then the cost per person is as follows (must be payed 60 days in advance):
1. Baggage UP from Kashgar to basecamp: $3/kilo above 32 kilos.
2. Baggage DOWN from basecamp to Kashgar: $3/kilo above 32 kilos.
