Perfect for extended backpacking trips, the classic Mountainsmith Circuit 3.0 internal frame backpack offers more than 5000 cubic inches of storage space. The Circuit 3.0 delivers durability and an array of features at a budget-friendly price.
Utilizing Mountainsmith's patented Load Dispersion Technology (LDT) suspension system, the Circuit 3.0 is designed to comfortably haul heavy loads. Twin aluminum stays cross in an "X"-pattern, efficiently distributing weight, providing better load control and increasing flexibility by creating a central pivot point. The suspension is wrapped in an airmesh fabric that wicks moisture. The Circuit 3.0's suspension is adjustable to fit a torso range of 18-22". A dual density waistbelt is reinforced with supportive plastic. Firm foam supports pack weight and provides cushioning under the load while softer foam nestles close to the body, 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 Circuit 3.0 is perfect for the backpacker who considers organization and pack access a priority. A detachable divider between the top loading main compartment and front entry sleeping bag compartment allows for organization and separation of wet and dry gear. When hauling longer items or in need of access between the two compartments, you can disconnect the divider and convert the Circuit 3.0 to a single, large compartment. The top lid houses a pocket for further storage and a clear panel/packet allows you to view a map without having to remove it entirely. Large side pockets enable you to organize gear and provide quick and easy access to contents. Pass-throughs behind the pockets allow for hauling of longer items like tent poles or collapsed trekking poles. An additional front, zippered compartment features internal organization sleeves and a fleece-lined optics pocket.
Other features on the Circuit 3.0 include a spindrift collar for full protection of pack contents and trekking pole and ice axe attachment points. An internal lined pocket with dual exit ports makes the Circuit 3.0 hydration compatible. Exterior mesh pockets make it easy to grab water bottles while on the move.
