Long pants, shirt and jacket

For your hike, you should wear long pants and a jacket. The temperature can be warm during the day, but it can also drop at night and early in the morning. You’ll want to have a jacket that is lightweight and has room to layer underneath it.

Your hiking shoes

Hiking shoes are designed for comfort and support, and they’re not just for hiking. They have a stiff sole to prevent slippage, which can be dangerous if you’re climbing over rocks or walking on muddy trails. They also have good grip on the sole so that you don’t slip in mud or ice patches.

Your best bet is to wear hiking boots with ankle support since this will help protect your ankles from injury when going up steep inclines or down steep declines. If you don’t want hiking boots but still want some protection against rough terrain, try out trail running shoes instead—they tend to be lighter than regular hiking boots but provide better traction on slippery surfaces like mud or snow.

Sun protection (long sleeve cotton shirt, wide brimmed hat and sunscreen)

You should always wear sunscreen when you are in the sun. It’s important to protect your skin from sunburn, which can cause serious long-term damage. You can get a wide brimmed hat to shade the face and neck, or even better: a baseball cap with a neck flap that goes down past your ears. If you do not have one of these hats already, consider buying one for this trip—they’re very helpful!

Wear sunglasses to protect your eyes from the sun, UV rays, and dust, dirt and debris. While hiking in Colorado in September you will be exposed to all of these elements. One of the best ways to protect your eyes is by wearing sunglasses that shield them from the wind as well.

Sun Damage: The sun’s ultraviolet (UV) rays can cause sunburns and skin cancer if they are not properly protected from exposure. Many people associate these kinds of problems with summer months when they spend a lot more time outdoors than during other times of year but this isn’t always true; even on cloudy days outside you can still get burned by UV light rays that manage to filter through cracks between clouds or reflections off water surfaces or snow fields – especially if those surfaces reflect light at an angle parallel to where you’re standing! Wearing quality sunglasses is one way you can help prevent this kind of damage while hiking Colorado in September weather conditions which tend toward cloudy skies but still pose some risk due their reflective qualities

Water bottle and water

You can never bring enough water on a hike. In Colorado, you’ll be exposed to the elements and exerting yourself more than you might at home. That means that hydration is important for your body and your energy levels. You don’t want to leave your bottle at home because it takes up space in your bag, but if it has to come with you, make sure it doesn’t weigh down your daypack or backpack. A collapsible bottle is ideal here—they pack down small but expand when full so they don’t take up too much room in your bag.

Having something easy to drink from can also help keep you feeling refreshed as well as energized during longer hikes or multi-day treks. Look for a water bottle that has a wide mouth opening so ice cubes can fit inside without taking an extra hour out of your day trying not to spill them everywhere (and wasting precious water). If possible, find one that allows easy refills so there’s no waste in carrying around an empty container all day long!

Food: energy bars or dried fruit

Dried fruit is a great source of calories when you’re hiking and has a long shelf life. You can buy it in bags at the grocery store and keep it in your backpack for easy access. Dried fruit also makes a good snack on the go, which is helpful when you’re navigating trail obstacles or scrambling up steep slopes to get to the top of something (like Mount Elbert).

Extra clothing and first aid kit in a backpack

  • Wear extra clothing and a first aid kit in your backpack. If you are hiking with a group, make sure everyone has an adequate amount of food and water. If you are hiking alone, make sure to have enough food and water for yourself to get back safely to the trailhead or car.
  • Listen carefully to instructions from park rangers about weather conditions before going on any hike or mountain climb.
