Understanding Hiking Backpack Types

Hiking backpacks come in several styles, each designed for different lengths of trips and types of terrain. Day packs are the smallest, typically ranging from 15 to 30 liters, perfect for short hikes where you only need essentials like water, snacks, and a light jacket. For longer day trips or ultra-light overnighters, a 30-40 liter pack offers a bit more room. Multi-day backpacks, often called internal frame backpacks, range from 40 to 70 liters and include a sturdy frame to support heavier loads.

If you're planning a multi-day trek, an internal frame backpack is the way to go. These packs have a built-in frame that transfers weight to your hips, reducing strain on your shoulders. The Shasta 55L is an excellent example of a technical frame pack that offers ample storage and support for extended adventures. For day hikes, a lighter option like the Ridge Day Pack provides just the right amount of space without weighing you down.

Ridge Day Pack
Ridge Day Pack
  • Day packs (15-30L) for short hikes
  • Mid-size packs (30-40L) for longer day trips or minimalist overnights
  • Internal frame backpacks (40-70L) for multi-day expeditions

How to Choose the Right Hiking Backpack Size

The capacity of your backpack should match the length of your trips. As a rule of thumb, a day hike doesn't require more than 30 liters, while a weekend trip might need 40-50 liters. For week-long adventures, you'll want 50-70 liters. But remember, bigger isn't always better—a larger pack encourages you to carry more, which can lead to unnecessary weight and fatigue.

To measure your torso length, have a friend measure from the base of your neck (the prominent C7 vertebra) down to your hip bone. This measurement helps you choose the correct pack size. Most packs come in small, medium, and large, and some offer adjustable torso lengths. The Shasta 55L, for example, features an adjustable harness to accommodate different torso sizes, ensuring a custom fit.

  • Measure your torso length for the correct fit
  • Match capacity to trip duration: day hikes (15-30L), weekends (40-50L), week-long (50-70L)
  • Try on packs with weight to test comfort

Key Features to Look For in a Hiking Backpack

When comparing backpacks, pay attention to the features that matter most for your hiking style. A hydration reservoir sleeve is essential for staying hydrated on the trail—many packs, like the Mist Hydration Backpack, come with a built-in sleeve and hose port. Look for multiple compartments to keep your gear organized, and external attachment points for trekking poles or a sleeping bag.

Weather resistance is another crucial feature. A rain cover or waterproof material can protect your gear from sudden downpours. The Poncho Backpacker is a clever accessory that covers both you and your pack, keeping everything dry. Additionally, consider the hip belt and shoulder straps—they should be padded and adjustable to distribute weight comfortably. Ventilated back panels are a plus for hot weather hikes.

  • Hydration reservoir sleeve and hose port
  • Multiple compartments for organization
  • External attachment points for gear
  • Weather-resistant material or included rain cover
  • Padded hip belt and shoulder straps

Fit and Adjustments: Getting the Perfect Fit

A properly fitted backpack is crucial for comfort and injury prevention. Start by loosening all straps, then put on the pack and tighten the hip belt first—it should sit snugly on your hip bones, transferring most of the weight to your hips. Next, adjust the shoulder straps so they fit comfortably without digging into your shoulders. Finally, adjust the load lifter straps to pull the pack closer to your body.

The torso length adjustment is key. Many packs, like the Shasta 55L, offer a range of torso lengths, so you can fine-tune the fit. For a day pack, the Ridge Day Pack offers a simpler, one-size-fits-most design that still provides a secure fit. Remember, a pack that fits well should feel balanced and stable, with no pressure points.

  • Tighten the hip belt first to transfer weight to hips
  • Adjust shoulder straps to avoid pressure points
  • Use load lifter straps to stabilize the load
  • Test the fit with a loaded pack before buying

Packing Tips and Organization

How you pack your backpack affects its balance and your comfort. Place heavy items close to your back and in the middle of the pack, around your shoulder blades. Lighter items like clothing can go at the bottom, and often-used items like snacks or a rain jacket should be in easy-to-reach pockets. Use packing cubes to keep everything organized and compressible.

For day hikes, a smaller pack like the Ridge Day Pack might have a single main compartment and a few pockets. Use a hydration reservoir for water to save space and keep your hands free. For longer trips, consider a pack with a sleeping bag compartment and side pockets for water bottles or trekking poles. The Deluxe Duffle is a great option if you're combining a hike with a road trip, offering spacious and durable storage.

  • Place heavy items near your back and mid-pack
  • Use packing cubes for organization
  • Keep frequently used items accessible
  • Use a hydration reservoir to save space

Specialized Backpacks for Specific Activities

While a general hiking backpack works for many situations, some activities call for specialized designs. If you're cycling to the trailhead, a bike frame bag or a handlebar pack like The Burrito Handlebar Pack can carry your gear without compromising your ride. For water sports or boating, a dry bag is essential to keep your belongings dry.

For those who prefer a minimalist approach, a waist pack like the H2O Mojave Waist Pack offers a lightweight way to carry essentials on short hikes or runs. And if you're traveling, a duffel like the Deluxe Duffle provides versatile storage that's easy to carry. Consider your primary activities and choose a pack that meets those specific needs.

  • Cycling: bike frame bags or handlebar packs
  • Water sports: dry bags
  • Minimalist: waist packs
  • Travel: duffels

Choosing the right hiking backpack is a personal decision that depends on your trip length, the features you value, and your body type. By considering the type, size, fit, and features, you'll find a pack that enhances your outdoor experience. Remember to try on packs with weight and adjust them properly. With the right backpack, you'll be ready for whatever adventures lie ahead. Happy trails!
