You can rent sleeping bags and jackets from trekking shops in Thamel (Kathmandu) or Pokhara, a deposit is usually required. Your guide may be able to help you with this. If your guide does go with you to help you rent gear please compensate them for their time. We can also rent sleeping bags both standard and feather (lightweight smaller ones). We may be able to rent jackets but check with us on size and the number needed for availability.
Send us a message if you are interested in renting gear.
