Rated 5 out of 5 by from Awesome Pack! I bought this pack just prior to starting the Wonderland Trail in Rainier and it performed incredibly well! It was easy to adjust, super sturdy, and able to accommodate 10 days worth of food and gear comfortably. I was impressed with how it handled about 40+lbs of weight. The pack is well-constructed and surprisingly light. I backpack for a living and am pretty picky when it comes to gear. This is my new favorite piece of gear :) [This review was collected as part of a promotion.]

Rated 2 out of 5 by from Carries well but flaws in stitching are a problem The horizontal compression straps on this pack really help to center a load. As a result the pack carries really well. The shoulder strap pouch is very handy and the pack feels sturdy in comparison with other lightweight packs. However, the stitching on the inside water reservoir pouch came completely unraveled before I had even used the pouch. This has caused me to question the pack's durability. I sent a message to Sierra Designs asking about the availability of a replacement pouch but received no reply. Based on that experience, I cannot recommend this product.

Rated 5 out of 5 by from Thoughtful design A thoughtfully designed pack. The compression strap design allows it to expand or contract between 40-60 liters keeping contents packed tightly so the carrier is always in balance. Like any new piece of gear, it takes time getting used to the fit as the pack rests on the lower back and shoulders to reduce sweaty back syndrome. A great balance of weight to durability and can handle a heavy load comfortably. The sizing demonstration video is also spot on. Although the mesh is lightweight, a more durable material for the side pouches would be preferable. A great pack at a great price. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Practical pack I have wanted to find a lightweight backpack. I was interested in this pack for design. (such as: a wide belt, adjustable capacity, and the lid), When I got this pack for Fjallraven Thailand Trail hiking (4 days, 12-13Kg, total 49km), at first I was worried that the pack would be too big for me who is 157cm tall, but after adjusting the strap, I felt suitable. Very satisfied with this backpack. I thought the only disadvantage is that the shoulder width is wider because the designer is male, but it has no big impact.

Rated 5 out of 5 by from Super light and well thought out I have several different backpacks and decided to get the Flex Capacitor as a light weight option for light hiking but I soon realized it can do anything I need it to do and it quickly became my preferred bag. The suspension design is excellent and air flow to your back is the best. You can definitely feel Andrew Skurka's design influence because everything has been very well thought out...Very interested to see what they do in the future to make this pack even better!

Rated 5 out of 5 by from Great all around pack I wanted a cross between the ultralight stripped down style of a frameless bag and the Cadillac style bells and whistles of an osprey. This pack fits nicely in the middle. Not as comfortable as the ospreys but carries well and is more versatile. I would prefer it have a “shove it” style pocket on the outside but I have learned to adapt. Great product. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Unbeatable Multi-Purpose Pack I've been waiting for this pack to be released for some time now and have read a lot about it on Andrew Skurka's blog. Although I have not taken it for a trip yet, I CAN speak to the quality of the craftsmanship and materials used along with design principles. I usually backpack with an Osprey Atmos and love that pack, but was looking for something much more simple and a lot lighter. My Osprey is close to 5 lbs where this pack is closer to 2.5 lbs. I'll take that weight savings every day of the week! The water bottle pocket on the right shoulder harness already seems like a no-brainer. Even if all you are doing is using a bladder, you can still use that pocket to store the hose so it's not collecting dust and dirt before it's put in your mouth. I'm also already a fan of the idea that the pack can be tightened up after loading - no one likes shifting weight when walking long distances. I know a lot of packs can crumple or become uncomfortable under heavier loads too. The FC has been tested with loose loads up to 70lbs and still performed comfortably. You can see a video of this on the Sierra Designs website. I find the fit of the pack to be excellent when loaded up. The straps are all simple to adjust and do not require a second person to assist with adjustments which will be super convenient when doing long trails by myself. I'll try to remember to come back and update the review once I've had a chance to take it for a spin. Thanks! [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Revision of previous negative review In an earlier review of the Flex Capacitor I noted that Sierra Designs failed to respond to my request for help with a quality control issue in the stitching on water reservoir pouch in my pack. The company has now sent me a new pouch so the issue has been corrected. Sierra Designs stands behind their product. [This review was collected as part of a promotion.]
