If you enjoy rock climbing, then winters can be problematic since most of your favorite climbs aren t exactly accessible, so ice climbing may just be the answer to your problem. Don't add too many items that add to the weight of the backpack or you will tire out quickly.
Ice climbing boots require more insulation than for alpine climbing since it s important to keep ice and snow from entering the boot. Ensure that you are aware of insect bites and stings, plants and weeds that may cause allergic reactions, exposure to various climactic conditions. Hiking to the top of a mountain is incredibly rewarding.
Be careful about not eating too much salty foods when doing heavy hiking in high heat or desert areas though, because you can become dehydrated more quickly. A tent which refuses to stay up due to some flaw is not going to be of much help to you and neither is a flashlight with no batteries or a first aid kit with outdated medicine. Even on longer backpacking trips, I use thin nylon socks and lightweight running shoes.
Like everything that you buy, a flashlight too must be purchased keeping all your requirements in mind. You should also develop a routine for keeping your feet dry and comfortable.
