Essential hiking gear and equipment
Before you hit Boulder hiking trails, make sure you have the essential hiking gear and equipment.
Here's a checklist of items to pack:
Hiking Boots: A sturdy pair of hiking boots is a must.
Hiking Poles: Did you know that when you use trekking poles, you're getting a full body workout? Hello toned arms and shoulders.
Also, according to The Sport Journal, using hiking poles can reduce compressive force on your knees by up to 25%. Learn all the benefits of using hiking poles.
Backpack: Strap on a comfortable backpack that offers enough room to carry all your essentials, like lots of water, snacks, extra layers of clothing, a first aid kit, and navigation tools.
We love the Osprey Sirrus and Stratos series.
Navigation Tools: Carry a map, compass, and/or a GPS device to help you find your way on Boulder hiking trails. Familiarize yourself with the route beforehand and always be prepared for changing weather conditions.
Summer in Colorado means thunderstorms often roll in around noon, so start your hike early and prepare to have a Plan B.
Layered Clothing: Colorado's weather can be unpredictable, so it's essential to dress in layers. Start with a moisture-wicking base layer, add insulating layers, and top it off with a waterproof and windproof outer shell.
Among some of our go-to things of what to wear while hiking:
Patagonia Torrentshell Rain Jacket
Nano Puff Jacket - an excellent three season jacket and layer
Free Fly Highmile Joggers - perfect comfy, style and durability for hiking Colorado trails
Food and Water: Take along high-energy snacks and plenty of water to stay hydrated throughout the hike. Consider bringing a water filter or purification tablets for refilling water from natural sources, in case you run out of water. We use a 2L or 3L Water Reservoir — this affordable reservoir is easy to fill.
Sun Protection: Protect yourself from the sun's harmful rays by wearing sunscreen, sunglasses, and a hat. The higher altitude can intensify the sun's effects, so lather on the sunscreen before you hit the trail. Tanya and I both have this Sun hoodie - a must have in Colorado
Emergency Essentials: Carry a whistle, flashlight, and a lightweight emergency shelter in case of unexpected circumstances. It's always better to be prepared for any situation. Bring a small Med kit.
