The ULA Circuit is an easy choice when deciding what backpack to purchase. It can carry big loads with comfort and durability and weighs less than 41 oz. This pack is nearly indestructible made with ULA 210 Robic fabric. You can use it for 2500 miles with minimal signs of wear. The design of the Circuit is a 1.2 oz. carbon fiber and Delrin suspension hoop in conjunction with a dense internal foam frame and a single aluminum stay, which provides back panel support, load control, weight transfer, and pack rigidity without limiting your range of movement.
Hipbelt Sizing: (Please let us know what size hipbelt you want in your purchase notes)
Choosing A Shoulder Strap Style:
J straps are traditional and work best on men and women with average builds. If you are very large in the upper body you might need XL shoulder straps. Men with athletic builds who have strong square shoulders will find the S straps work better. If you are a climber, weight lifter, triathlete or similar, consider purchasing the S strap.
Measuring Your Torso
Length: Torso measurement is the best guide for proper pack fit. If you are between sizes on the torso choose the smaller size. Conversely, if you are between sizes on the hip belt, choose the larger size. Follow these steps to accurately measure your torso. Stand upright and tilt your chin to your chest. Locate the largest lump on the back of your neck located close to the base of your neck. Make sure your pants or short are sitting just above the top of your hipbone. From the large bone at your neck, measure the length and natural curvature of your spine to the top of your waistband. This is your torso length
