You're standing at your local outdoor retailer, staring at the multitude of backpack options. Do you need a pack made of ripstop nylon? What capacity do you need? And what about all those features? We've all been there trying to select the perfect bag for our needs. We are here to offer some tips that will eliminate some confusion and aid your choice.
Consider Your Activities Before Purchasing a Pack
No matter what activities you enjoy, a daypack is an essential piece of gear. However, some are tailor-made for specific uses. Before you choose one, you'll want to determine your primary purpose for a daypack. If you need a bag that can accommodate a variety of your activities, note that too.
With a hiking specific pack, you're looking for one that can carry everything you need for a day hike (water, extra layers of clothing, first aid kit, etc.). It also must maintain a level of comfort and support. Typically, hiking packs will range in capacity of around 15 to 30-liters and come with with a few key features. Look for compartments for smaller items (phone, maps, compass), a hydration compartment, carry options for trekking-poles or ice axes, and some side pockets for water bottles or sunscreen. If you're set on having a pack that is super comfortable to wear, pay extra attention to cushioning and ventilation.
Depending on your style of climbing, you may look for smaller pack around 12 to 20-liters that would be great to carry up with you on multi-pitch routes. Or you may be looking for a slightly larger pack that will cart all of your gear to the base of a crag. Either way, you'll probably want to look for a pack that has a more narrow profile. This allows for greater range of motion for your arms and shoulders. Also, pay special attention to comfort and consider plenty of structure to handle heavier loads. Climbing packs may also have additional features such as daisy chain attachments on the outside for clipping gear. We found the REI Co-op Flash 18 to be a great multi-pitch climbing companion.
Alpine and Ski Touring
Packs for skiing tend to be on the larger side, 20 to 40-liters, and favor the fast and light attitude over flashy features. For these bags, a smooth and narrow profile is a plus, and a sternum strap and hip belt are essential. Most of these types of packs will have a place to stow your ice axe, and sometimes bonus feature compartments for crampons, a shovel, and a probe. If you are specifically looking for a ski touring pack, you'll also want to pay close attention to the ability to attach your skis to the pack. None of the contenders reviewed in this test were designed specifically for skiing, but we found the Deuter Speed Lite 20 to work for this purpose.
Trail Running and Adventure Racing
Typically, these types of packs run on the small side (25-liters or less) and are really for essentials only, such as the Flash 18.
Around Town, Commuting, and Travel
All of the daypacks we tested can fit into this category. Some of them, however, definitely work better than others for around town use. Ideally, an around town pack will have a compartment to fit a laptop. Look for a few other organizational compartments for writing utensils etc. A padded back panel is also helpful in keeping stuff from poking your back. You may even want some cycling specific features, such as a bungee helmet clip and blinker attachment.
How to Choose a Daypack
Here are the main factors to consider when selecting your pack.
Twenty to 30 liters is the ideal volume for a daypack. The smallest pack we tested was the Fjallraven Kanken 16, while the largest was the Granite Gear Virga at 26 liters. Unless you seek technical use, like alpine summits or ski touring, anything over 30-liters is too big. That begins to enter into the realm of multi-day backpacking and becomes excessively bulky for just day use. Anything much smaller than 20-liters becomes difficult to fit the essentials. The REI Co-op Flash, Deuter Speed Lite, and Osprey Talon 22 are on the smaller end of this scale, and each held our hiking specific essentials.
Ventilated Back Panels
While Jansport invented the first daypack in 1967, technology has come a long way. Those first day packs that were adapted from those used to haul books around in school. An awesome advancement is the implementation of ventilated and structured back panels. There's little worse than hiking on a bluebird day and feeling like you're wearing a warm sweater on your back that's just collecting sweat.
Many of the new packs are using a tensioned back panel design system. This is a rigid mesh panel that sits against the back and a frame that pushes the load slightly away from the back, leaving airspace between. This design compromises the carrying capacity of the pack. We did not test any models like this for 2017. Our team does not feel they are worth it. The result is indeed a steady flow of air behind you. However, because the weight is not situated close to your body, there is a trade-off. The pack may begin to pull you backwards with heavier loads. With daypack loads we found that this feature is ok with some. You are typically carrying much less weight than with a backpacking pack.
Weight vs. Features
Some daypacks have a fast and light attitude and are simple, straight forward bags. Others come loaded with a full range of bells and whistles. Extra features can make your life easier, especially with organization within the pack. You trade convenience for added weight. The trick is figuring out what your specific needs are for your pack and balancing the features, you need with how much weight you want to carry. No matter how much or little you put in your bag, remember that you'll always have to carry the base weight of your pack.
Top-Loader vs. Panel-Loader
Packs come in two different loading styles: top-loaders and panel-loaders. Top-loading packs tend to be lighter and more simplified. The top-loading design is more in-line with a backpacking pack where all of your gear fits into a single compartment from its top access point. These types of daypacks are great for fast and light ascents. Top loaded closures are also more durable than zippers.
Panel-loading packs usually have one or more compartments accessible through a curving zipper. These bags tend to have more organizational features and are easier to rifle through once loaded. Panel-loading packs also tend to be more versatile for activities beyond hiking.
While only one pack we tested included a rain cover, most companies also sell them separately. If you're planning on hiking in high humidity or rainy weather, consider purchasing one. These will cover the pack body, helping ensure that its contents will remain dry. Also, they look nicer than a garbage bag.
How to Size and Fit a Pack
Once you've chosen your must-have attributes and figure out what activities you'll pursue, the last and most important step is fit. Ideally, you want most of your weight sitting on or close to your hips. Therefore, it is imperative that the pack you buy fits your torso. Most daypacks come in only a single size. Choosing the correct size is not as important as with a backpacking pack, but it is still a factor to consider. Make sure it will be comfortable.
Measuring Your Torso Length
You'll want to measure the length of your torso to makes sure the pack will fit on your back. To measure your torso, you'll want to use a flexible tape measure. Stiff construction measuring tapes tend to complicate this task but can get you close. Grab a friend for this measurement, and have them locate the largest bony bump at the base of your neck. This is your C7 vertebra. The C7 is easiest to locate if you tilt your head forward, and will be the top of your torso measurement.
Then, locate your iliac crest, which is where your pack will hold the brunt of the load weight. With hands on top of your hips, fingers wrapping around your pointy pelvic bones, point your thumbs to your spine. This marks the iliac crest and the base of your torso measurement. Have your friend measure between your C7 and the spot between your thumbs. Compare this measurement with the size range of the pack you are eyeing.
Note that you can adjust the harness of the Osprey Talon 22, Editors' Choice winner, to fit different torso lengths. This makes this pack even more versatile for many users.
Though the sizing around your hips is a little less important, it may be helpful when looking at packs with interchangeable hip belts. A well fit hip belt will sit about an inch above your latitude line, which runs out from the high points of your hip bones.
You're looking to measure around this latitude line. It is slightly lower than your waist line; your hip belt size will differ from your pant size. To figure out this measurement, wrap your tape around your hips, making sure that it sits on top of your hip bones.
If you are struggling or are unsure with any of this, your local outdoor retailers will have staff prepared to assist you. A professional measurement will ensure that you will get a well-sized pack.
Also, if you're looking at an Osprey pack, they have a comprehensive guide that may help you take this measurement on your own.
Adjusting Your Pack
While some daypacks may not have the adjustability features of a backpacking pack, some do. Consider the Osprey Talon 22. It is very adjustable. Others have varying degrees of adjustability. According to the Gregory fit guide, "a pack is not carried, but worn". It is important to adjust your pack every time you throw it on your back. Double check that the load is situated and comfortable on your body.
You'll want to start by loosening all the straps, including the hip belt, and place the pack on your back.
First, you'll buckle the hip belt and tighten it. Make sure it straddles your hips, and that the padded sections, if any, wrap centered over your iliac crest.
Next, you'll batten down the hatches with your shoulder straps. By doing so, your straps should hold the pack close to your body, but not carry the weight. The anchor points should sit one to two inches below the top of your shoulders.
Load Lifters (if applicable)
Many daypacks have "load lifters" that help take pressure off your shoulders. They suck the pack into your back. The straps are near your collarbones and should angle back and up toward the pack at a 45-degree angle. They work to pull weight off of your shoulders. Gently tighten these straps, but take note that over tightening them will create a gap between your shoulders and the shoulder straps.
Most daypacks come with an adjustable the sternum strap. Slide this up or down on the shoulder straps to find a comfortable height on your chest. Aim for just above nipple line. These straps pull the shoulder straps inward to a pleasant position on your shoulders. Buckle and tighten this strap, but make sure your arms are still able to move freely.
Last but not least, you may want to tweak a few things to make sure your load is equalized. Your body is rarely happy with a pack on your back, but it shouldn't be screaming. Your daypack may be equipped with stabilizer straps on either side of the hip belt. These allows you to bring the pack even closer to your body, creating greater stability for the load. You can also loosen the tension in your shoulder straps just a smidgen to ensure that your hips carry the majority of the weight.
Other Uses For Daypacks
The primary appeal lies in the fact that they are so versatile. Few other products can transition smoothly from the outdoors to office. These are the types of packs that can go with you anywhere, from a short shady hike to an afternoon reading a book on the beach, to a stroll to the grocery store. We evaluated these packs for their usefulness on day hikes. There are several other reasons you may want to consider a daypack.
Backpacking gear is becoming lighter and more compact, and the trend is to take less and lighter gear. If you are the type of backpacker who carries ultralight sleeping bags and ultralight tents, you may find that you no longer need a standard backpacking backpack. When your entire pack (without food and water) weighs less than 12 pounds, often a day-specific pack will work, or you should consider an ultralight backpacking pack. Most diehard ultralight backpackers will want a pack minimally designed. The Granite Gear Virga 26 is an excellent pack for this use and is the only pack reviewed that was well suited to ultralight backpacking and for use as a daypack.
With checked baggage fees rising, many are looking to pack for trips using only carry-on luggage when possible. One great way to accomplish this is with a large "personal item" in combination with your carry-on bag. The Osprey Daylite Plus was one of our favorites for this. Many of the small packs reviewed meet airline requirements for a personal item. We advise double checking guidelines before you buy.
While a carry-on bag beats checking luggage, one step above is a bag that fits under the seat in front of you. The larger packs reviewed can substitute for your carry-on luggage and can be compressed enough to slide under a seat. That said, we prefer to bring a laptop backpack because they are more stylish and better equipped to protect your computer. We used a hybrid between a laptop backpack and a daypack, the Patagonia Arbor for OutdoorGearLab founder Chris McNamara's trip to see the New 7 Wonders of The World in 13 days. With so many tight flights, the trip was only possible because he used a day-specific pack instead of a carry-on.
