How To Be Better Prepared
1. Waterproof your Gear (Gore-Tex is not a solution).
You will carry less weight (as water) and your gear functions better when it was waterproofed.
2. Use a Vestibule
Nobody likes putting on wet boots before hiking. Get a reliable freestanding Tent that is quick to set up, has a vestibule, great waterproofing and a separate ground tarp is recommended too.
3. Know your surroundings - Find Shelter If Possible
It rained for 4 days in a row when I was in New Zealand but because we knew where the National Park hut was, we were able to start a fire to dry our clothes, oh what a luxury.
4. Extra Cover Is A Godsend
Even when going out for day hikes it's a good idea to bring along a tarp in case you get caught in the rain, our hammock tarp is a quick set up and will keep you dry for hours while you wait out the rain.
5. Bring a warm sleep system
Being wet and cold is a recipe for disaster if you have to camp in the rain. You need to be able to stay warm and comfortable whilst resting your tired body, it is critical.
