We offer the 40 liter Worksack in two distinct versions: the 40L and the 40B. The overall shape, volume, and innovative Cilo Gear systems are identical.
The 40L features a generous stow pocket on the front panel. This pocket is ideal for energy bars, cameras, and the little things you keep needing throughout the day. A Pocket-in-Pocket improves organization even further. Access is easy when you clip the pack in on the back panel haul loop.
AMGA certified guide Marty Molitoris weighs in on his 40L:
The 40L was the perfect size/weight for the objectives—plus being able to compress it allowed for me to use it as my approach pack and the pack I used to climb with. It was big enough to fit all the essentials; small enough to keep from stuffing that “extra” item in. The pocket was especially handy when I used the pack without the lid.
Marty used the 40L recently while passing his AMGA Alpine Exam.
40B Worksack
We introduced the 40B after extensive feedbacka number of top climbers including Mark Twight, Kelly Cordes and Maxime Turgeon. They wanted a smaller bag for “day” trips and general use. They wanted nothing extraneous, but they wanted the durability of our 60L WorkSacks.
The 40B eliminated the stow pocket and 35 grams. The addition of the internal load compression strap controls the main compartment contents, and effectively transfers the load for quick, active movement and climbing.
How do you decide between the two? Is 35 grams a big deal?
It comes down to the style of your climb and to your style as a climber. Let’s assume that the pack easily holds all of your gear, but you want better access to some of it and the benefits of the organizational pockets. Then the 40L will help you stay organized, even stripped of the lid for a day’s climb. On the other hand, perhaps you’re planning to carry over, or simply don’t need any crutches for organization. The 40B carries your bivy gear as well as anything else, while keeping the pack as a simple top loader without any extra pockets.
