While $50 membership dues may seem like a lot, you can easily make your money back in discounts on caving gear, events, training, and more. There are also events you can only attend if you’re an NSS member, and caving organizations you must be an NSS member to join! And remember that the NSS has a discounted student membership for members under the age of 26!


  • Expertvoice: The NSS has partnered with Expertvoice to bring pro deals to NSS members, up to 45% off! These vary through the year but often cover clothes, hiking gear, and other outdoors gear. Instructions here.

  • Highline Ropes: HIGHLINE offers rope at 35 cents a foot for new members’ first order! This is a great deal for starting your gear collection out right!

  • Inner Mountain Outfitters. IMO offers new members 10% off their first order of gear. Also, when the NSS sends out an anniversary pin to an NSS member that entitles them to that amount of one item at their store.
