Let’s face it, every mother has a favorite child – ours is the Circuit. Weighing in at just over two pounds, we don’t think there’s a pack out there that can compare to the load-carrying capabilities, comfort, and durability of the Circuit pack. If you have your total pack weight down to around 30 pounds and want to feel the freedom of traveling light, this is the pack for you. The Circuit has been the most popular pack on the Pacific Crest Trail for the past 3 years according to the Halfway Anywhere annual survey of PCT thru-hikers.

The Circuit pack utilizes a 1.2 oz carbon fiber and Delrin suspension hoop in conjunction with a dense internal foam frame and a single aluminum stay to give you excellent back panel support, maximum load control, weight transfer, and pack rigidity without limiting your range of movement.

The downward slope of your shoulder profile usually determines strap preference. You can assess your shoulder slope profile by looking in a mirror or having a friend look at the angle of your shoulder from the base of your neck to your shoulder point.

If there is relatively little or no downward slope, you have what is referred to as flat or squared shoulders.

If there is a noticeable downward slope, you have what is referred to as standard or sloping shoulders.

J-straps are the traditional straight straps. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.

S-straps contour body curves. They are best suited for people with standard or sloping shoulders, as their contoured shape better hugs your shoulder slope.
