Its 0.1 micron absolute filter removes harmful bacteria, protozoa, and sediment, providing safe drinking water.
This system is highly versatile. It can attach directly to the included drinking pouch, a standard disposable water bottle, or the tube of a hydration pack.

Darn Tough Vermont Men’s Hiker Midweight Micro Crew Sock
Foot comfort can make or break a hike, and it starts with a great pair of socks. Darn Tough socks are knit in Vermont with a blend of merino wool, nylon, and Lycra spandex. The merino wool naturally wicks moisture away from your skin, helping to keep feet dry and reduce blister-causing friction.
The midweight cushion provides comfort and protection underfoot, while the True Seamless toe eliminates irritating seams. The micro-crew height sits just above your hiking boot, offering coverage without bulk. These socks are also known for their exceptional durability and are backed by a lifetime guarantee.

The shoe features a secure, comfortable fit with Salomon’s SensiFit technology and a quick-lace system for easy adjustment. The protective toe cap guards against rocks and roots, while the waterproof versions (available in some models) help keep your feet dry in wet conditions. Their lightweight and responsive design reduces fatigue over long distances.
Buying Guide: What to Look For in Your Day Hike Essentials
Packing for a day hike seems simple until you’re halfway up a trail wishing you had something you left in the car. I’ve been there. The key is balancing preparedness with not carrying your entire closet on your back. Let’s talk about what to actually look for when picking the 9 items you need in your day pack for a day hike.
First, your pack itself. Don’t use an old school backpack. Look for a dedicated hiking daypack (20-30 liters is a sweet spot) with a hip belt. This transfers weight to your hips and saves your shoulders. Padded shoulder straps and a breathable back panel are non-negotiable for comfort. For hydration, you have two main choices: a classic water bottle or a hydration reservoir (like a CamelBak). Reservoirs let you drink hands-free, which I prefer, but bottles are easier to refill and monitor your intake. Consider a pack with a dedicated sleeve for whichever you choose.
Your navigation tools are critical. A phone with a mapping app is great, but it can die. I always carry a physical map and a compass, and I know how to use them. Look for a detailed topographic map of the specific area. For your headlamp, brightness (measured in lumens) matters, but so does battery life and weight. A model around 150-300 lumens is plenty for trail use. Check if it uses standard or specialty batteries.
When selecting a first-aid kit, don’t just buy the smallest, cheapest one. Open it up. It should have supplies for blisters (moleskin!), gauze pads, adhesive bandages, antiseptic wipes, medical tape, and basic medications. You can build your own, which I often do, to tailor it to your needs. For sun protection, a broad-spectrum sunscreen of SPF 30 or higher is a must. Look for sweat-resistant formulas. A wide-brimmed hat and UV-blocking sunglasses round out your defense.
Finally, your extra layers. Cotton kills, as the saying goes. Your insulation layer (like a fleece or puffy jacket) and your rain shell should be made of synthetic materials or wool. They keep you warm even when wet. The rain jacket should be truly waterproof, not just water-resistant, and pack down small. Remember, the goal is to carry these items and hopefully not need them, but you’ll be incredibly grateful you have them if the weather turns.
FAQ
How much water should I carry for a day hike?
This depends heavily on the weather, your intensity, and the hike’s length. A good rule of thumb is to plan for about half a liter per hour of moderate activity in moderate temperatures. For a 4-hour hike, that’s at least 2 liters. Always err on the side of carrying more, especially if there are no reliable water sources on your trail. I often use a 3-liter hydration reservoir to ensure I have enough.
Do I really need a physical map if I have my phone?
Yes, you really do. Phones can break, run out of battery, lose signal, or get dropped in a stream. A physical map and compass are reliable, never-run-out-of-battery tools that could be vital if you get lost. I use my phone for convenience and the GPS, but my paper map is my backup plan. Make sure you know the basics of reading it before you head out.
What kind of food is best for a day hike?
You want high-energy, low-mess foods that won’t get crushed. I avoid anything that will melt or turn into goo. Great options include trail mix, energy bars, jerky, whole fruit like apples or oranges, nut butter packets, and sandwiches on durable bread. The goal is to keep your energy steady, so pack more than you think you’ll need—hiking makes you hungry!
Can’t I just use a regular backpack for hiking?
You can, but you’ll likely be less comfortable. A dedicated hiking pack is designed to carry weight efficiently with padded straps and a hip belt. It also usually has accessible pockets for water and gear, and is made from more durable, often water-resistant, material. After switching to a proper daypack, my hikes became much more enjoyable because my shoulders didn’t ache.
What’s the most commonly forgotten item on a day hike?
From my experience and talking to other hikers, it’s often a simple thing: extra socks. Getting your feet wet can quickly turn a great hike miserable. A fresh, dry pair of socks (wool or synthetic) can feel like a miracle. Other frequently forgotten items are a headlamp (even for day hikes, in case you’re delayed) and a basic repair kit, like some duct tape and a multi-tool.
How do I pack all this without it being too heavy?
The trick is to prioritize the essentials and choose lightweight versions where possible. Your big three weights are usually water, food, and extra layers. You can’t skimp on water, but you can choose calorie-dense, lighter food. For clothing, choose packable layers. Spread the weight out in your pack, keeping heavier items close to your back and centered. Remember, having the right 9 items you need in your day pack for a day hike is about safety and comfort, so every item has a purpose.
