Two hollow stays add the structure you need to carry 70-pound loads. and they can be removed for lighter alpine quests.

Meanwhile, a large, stowable front strap condenses the main compartment when you’re carrying a smaller load during those less gear-intensive missions.

Mountain Hardwear gave the pack its low-bulk FitLock waist belt to redistribute the majority of the load to your legs. The removable top lid features a rope strap for alpine climbing trips and utilizes glove-friendly compression straps to shrink the load on the go. The FlapTop design means that the pack remains weather-resistant with or without the top lid attached.

Your selection of a backpack depends on materials, construction, and features. Find out what’s best for you.How To Buy A BackpackThe keys to buying a backpack are fit and capacity. While fit should be determined by your body type, capacity (the types and amount of gear a pack is capable of carrying) should depend on intended use and length of trip.

Here is what to look for to determine what backpack is right for you.Pack styles and usesThe more weight you carry, the more supportive your pack needs to be.A waist or lumbar pack or small daypack is best if you are taking a short hike with little gearIf you’ll be carrying a bulky or heavy (10 pounds or more) load, or if you plan to be out for more than a day, consider an internal or external frame packBoth internal and external frame styles have a harness system comprised of shoulder straps and a hip belt; compression straps pull the pack and load closer to the bodyInternal frameRefers to a support system that is built into the interior of a packInternal frames transfer a large percentage of the pack’s weight onto the hips, which can bear far heavier loads than the shoulders. This frame style is comprised of a hip belt that works with an internal suspension system.The internal frame suspension system usually consists of one or more aluminum or carbon fiber stays that curve to fit your spineThe stays extend from the top of the pack to the hip belt, and their job is to stabilize loads and transfer weight to the hipsMany models also include a framesheet, often made of high-density polyethylene, to stiffen the back of the pack and allow for better weight transferInternal frames offer better balance because of their low profile and

close-to-the-body fitExternal frameThe first generation of framed packsThey feature a rigid support system, or framework (usually constructed of tubular aluminum), to which a pack and harness attachExternal frame packs transfer weight and stabilize loads, but are much more rigid than internal packsUsually have a wider profile than internal frame packs. On an open trail where balance isn’t a critical factor, this should present no major problems, but in the backcountry, the frame could snag on branches or get tangled in brush.Because the rigid frame keeps the pack away from your back, such models tend to be comfortable when used in hot weatherUsually less expensive than their internal frame counterparts because their design and production is less complicatedDaypacksDaypacks are ideal for carrying light loads over short distances.SizesGeneral purpose daypack capacity range is from 500 to 2,500 cubic inchesIn daypacks of 3,000 cubic inches or more – for ski touring or a long day of hiking–look for models with a framesheet and at least one internal stayA padded hip belt and padded, contoured shoulder straps are also nice to haveFeaturesThe features you choose should be based on your intended activityOutside mesh pockets are handy for carrying water bottles

The size you need depends on what you’ll be doing and the amount and type of gear you want to carry.For a warm-weather weekend trip (two or three days), look for a pack in the 3,500 to 4,500 cubic inch rangeFor a week-long trip or more: 5,500 to 7,000 cubic inchesAvoid using a pack that is too big.

Most people tend to fill available space, which makes for a heavier than necessary load to haul.Fitting tipsYour height has little bearing on what size pack you should wear; it’s your torso lengththat matters.If the pack is too long, it will sag onto your rear endIf it’s too short, it won’t support your lower backDetermining your proper pack sizeTo determine your torso length, measure from the seventh vertebra (the bony protrusion at the base of your neck between your shoulders) to the small of your back (level with your hipbones)For torso length less than 18″ (45 cm.), your suspension size will likely be SmallFor torso length between 18″ and 20″ (45-50 cm.), your suspension size will likely be MediumTorso length over 21″ (52.5 cm.), your suspension size will likely be LargeDetermining your hip belt sizeThe hip belt should cup your hips and when cinched tightly, the pads should not touchWomen with straight or narrow hips may prefer a standard hip beltWomen (and men) with more curve to their hips should choose a women’s-specific modelShoulder straps should anchor
