The same UL gear works in California, Oregon, Washington, New mexico, Colorado, Wyoming, Montana, Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine.
I might have been born in California but i have hiked across all those states using UL techniques and gear in the past three years.
I have not been to New Zealand but several hikers I met during my hikes live there and use the same techniques and gear as me.
Does the rain come up from the ground in New Zealand or something? Maybe my kiwi friends forgot to tell me that!
