Clothing

• Hikers should layer their clothing. Pack a base layer that wicks perspiration away from the skin as well as a soft shell jacket for the wind and cooler weather. Also bring an insulating layer such as fleece and a hard shell outer layer. Hikers should wear durable, comfortable boots and bring multiple pairs of thermal socks. The trail can be rocky and the high-altitude weather cold and wet.
  
  

Sleeping Gear / Backpack

• Hikers should bring a sleeping bag that fits in a compressed stuff sack and lightweight tent. Your sleeping bag should be down or synthetic and should be rated at 25 degrees Fahrenheit. A thermal sleeping pad to put on the ground will help keep you warm. Again, remember to pack several pairs of socks so you have a dry pair to wear at night. Your backpack should be comfortable and large enough for all of your belongings. Be sure to try out several before making your purchase. REI offers several comfortable and durable trekking packs at reasonable prices. Other good recommendations are the Lowe Neutrino and the Black Diamond Speed 30.
  
  

Miscellaneous

• Pack a pocket knife, headlamp or flashlight and a water bottle along with water-sterilizing tablets or a purification system. Sunblock and lip balm are essential. And don't forget toiletry items and insect repellent. In your first-aid kit, remember to pack plenty of ibuprofen to treat swelling and inevitable aches from the long trek. You may also wish to carry a blister repair kit, Band-Aids, antibiotic ointment and rubbing alcohol pads. Cloth bandages are essential to bring for use on a variety of injuries, from sprained ankles to cuts and bruises.
  
  In terms of food, if you are going with a hiking outfitter, most of your meals will probably be included in the price. If not, be sure to pack an adequate amount; you won't be coming across any shops on the trail. Pack food that is light to carry and is high in calories and salt. You will perspire a lot and burn an above-average number of calories on the journey.
