The rugged Mountainsmith Apex 100 internal frame backpack offers over 7000 cubic inches of storage space. Load-carrying capability and organizational features combine to make the Apex 100 an ideal option for extended backpacking trips.

Utilizing a Parallel Y-Frame adjustable suspension, the Apex 100 is designed to comfortably haul heavy loads by efficiently distributing weight, providing better load control and increasing flexibility. A dual-density, compression-molded backpanel is channeled to allow air to circulate, keeping your back cool and dry while in the backcountry. Fit is adjustable to accommodate torsos ranging from 17"-22" in length. A dual density waistbelt supports weight and provides cushioning while conforming to the contours of your hips. Adjustable shoulder straps, load-lifter straps and an adjustable sternum strap further enhance fit and comfort. Side and bottom compression straps allow you to cinch down your load for better stability and maneuverability.

The large top-accessed packbag of the Apex 100 offers a standard capacity of 6100 cubic inches and an integrated spindrift collars expands usable capacity to a full 7078 cubic inches. The height of the Apex 100's top lid can be adjusted to accommodate the expanded collar. The lid can even be detached entirely for use as a lumbar pack or shoulder sling. A vertical zipper on the front of the Apex 100 enables you to quickly put hands on contents without having to open the top lid. A separate sleeping bag compartment can be accessed through a zipper on the front of the packbag. This compartment is separated from the main packbag by an internal divider that can be unzipped to convert the interior of the Apex 100 to a single, oversized compartment. Large zippered side pockets serve as additional gear storage options.

Other features on the Apex 100 include trekking pole mounts, ice axe loops and daisy chain gear attachment points. An internal lined pocket and drinking tube exit port makes the Apex 100 hydration system (sold separately) compatible. External canted mesh pockets safely stow water bottles and provide convenient on-the-go access.

Great opportunity for a great product

Likes: This was a previous year model that was on clearance. Such a great value for all of the features:
1- fully adjustable for height, width, and more slight variations
2- great material construction and zipper design (i.e. number is f zippers and placement)
3- lightweight overall with solid equipment
4- great color and profile

Dislikes: Some zippers are positioned to be more exposed, thus an additional cover purchased may solve this (cover not included).

Caverous Pack that hauls it all!

Likes: I have taken this on three outings, two camp outs and one short backpacking trip. I have loaded this pack to its limits and it is more comfortable than my previous pack, a K2 Terraframe. Having been an external frame devotee, this is high praise. The fit/finish is top quality; the side and lid pockets are great. This is my first Mountainsmith backpack purchase, I would buy it again.

Dislikes: The front center pocket is not fully divided from the main compartment. The top is open, presumably to allow you to access the contents from the large top opening. This needs a closure, when my pack was laying flat, items tended to fall into the main compartment. I am an organizer and this is a problem. Also, the key fobs need their own small pocket, even if its just an elastic closure. They need more options for colors, perhaps they did, I bought this as a closeout. Really, these are minor issues but the only problems I see.

Likes: Omg best bag ever love it and so will my back.

Dislikes: Norhing at all.

Reviewed by Carl I. - March 6, 2015

Likes: The features of this pack almost seem endless. It was very easy to dial in the fit of the pack which felt very nice on the trail. With 100liters to work with, the compression straps let you take this pack on shorter trips without being overkill on size, however, on the longer treks you can carry plenty of food and extra warm/dry gear.

Dislikes: Nothing.
