We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

The Sierra Designs Flex Capacitor 40-60 Pack is a truly unique take on a lightweight backpack. Yes..that says Flex, not Flux, sorry time travelers. For the rest of us linear time travelers, this pack rocks a gusset system that easily expands from 40-60 liters. This is done with the easy adjustment of a few straps. The Y-FLEX DAC Pressfit aluminum stay provides an internal structure, meaning you can carry heavy loads comfortably. The EVA foam that pads the lumbar area and shoulder blades provide space for air flow between the pack and the back panel. Cutting down on the back sweat, whether this is an overnight trip, or thru-hike.

Product Reviews
Rated 4 out of 5 by from the dream of connoisseurs of universal equipment h Conclusions. It seems that with the Sierra Designs Flex Capacitor 40-60, the dream of connoisseurs of universal equipment has come true. If you are just starting to lighten your equipment, the Flex Capacitor is a good choice, because it will still hold everything you have and withstand the loads placed on it. And when your equipment is reduced in volume, tighten the front slings and get a wonderful and, at the same time, light (1250 g) backpack. If you usually go to the mountains for a few days - a week, but in the future think about longer trips or expeditions and doubt whether you will have enough backpack for 40-50 liters, Flex Capacitor will again be a good solution. Because +20 liters at any time. Do you often go to the mountains on your own, but from time to time you take your children with you and dream of extra volume in your backpack? Flex Capacitor again. Do you want to fly with hand luggage and do not want to buy a separate small backpack, which then have to cling to the outside? And here is the Flex Capacitor. In my opinion, Sierra Designs Flex Capacitor 40-60 is a great universal backpack with excellent weight and load, good strength, thoughtful details, good design and a good price for all these benefits. But if your loads constantly exceed 15 kg, I would advise to look in the direction of Osprey Atmos AG. Fill both backpacks with your weight in your favorite store and determine which one will be more convenient for you. Or, take the Flex Capacitor for a test in our #BankEquipment and play with it to your heart's content in real camping conditions. Advantages: incomparable transformer from hand luggage to 60 liter monster with perfect adjustment of the center of gravity, transformation does not require effort and time, extremely easy for the loads specified by the manufacturer, practical and beautiful design, large pockets on a belt, big side pockets with reasonable zoning of fabrics, large pocket on the strap, a large margin of safety in fabrics and accessories, good price. Disadvantages: it takes time to get used to the lack of a front elastic pocket, no reinkaver, you should improve the pullers on the runners, I miss the inner pocket on the valve.

Rated 5 out of 5 by from Solid Pack Got this pack for a short trip in the eastern sierras. It did a fantastic job with all the weight and never felt too heavy. All my gear was able to fit with room to spare. Loved the front water holders though I'd recommend softer plastic bottles for it. Overall a great pack.

Rated 4 out of 5 by from Flexible pack Seems like a great pack. Purchased for a thru hike that I haven’t gone on yet so I haven’t gotten too much time with it. But it’s comfortable when loaded. Plenty of ventilation on the back and the pockets are nice. Very cool that you have freedom to go between two different sized bags. Frame and hip belt are both removable for an even lighter pack for a quick day hike.

Rated 5 out of 5 by from a review that has purchased both the old and new m I thought it was just a simple color. ​ There were many revisions in the previous version. ​ The main fabric has been changed. ​ Gray is more stiff than the new black. ​ The new model was softened with a lower Dyer thread. ​ According to Andrew Skurka, who developed the product, the new fabric has improved tensile strength compared to the old version. The number of water bottle pockets has increased and the material of mesh has changed. ​ The mesh pockets that were only on the right side of the backpack shoulder strap ran on both sides. ​ Messi's material has also been changed to a lighter material. In addition, we added a part that holds the string to improve the fact that it was not handled well when using 40 liters. ​ I thought it was just a change of color and a sale, but a lot of the improvements have been made.

Rated 5 out of 5 by from Lightweight and Secure Ordered this bag for a hiking trip and it was the most comfortable bag of my group. It is very lightweight which was a concern when I unboxed it but the material is durable (just keep sharp objects from poking at it!). I was able to secure/compress the contents of my pack using the many straps on the face of the bag- nothing shook around inside as I hiked. This makes it much easier to keep balanced and feel in control when hiking. The interior of the bag is spacious but it is essential my one big open compartment. This is where the compression straps come in. The light weight of the pack is excellent but I packed clothes in/around items with rough/sharp edges to avoid any punctures or cuts to the thin-but-durable feeling material. If you pack smart and like a light/med weight camp setup this bag will be very comfortable. I carried around 30 lbs of community camp gear for 8-10 miles per day and the bag was comfortable. Can’t speak for more weight than that. The internal frame is small but helps prevent the back strain I’ve experienced with frameless bags.

Rated 5 out of 5 by from Updated Straps Look good While the older version’s notorious weak point were the volume straps, the construction on this looks really solid. I look forward to getting out on the trail with it.

Rated 5 out of 5 by from Nice Pack! Although I have not had a chance to run this pack through it's paces, I am already impressed with quite a few features. I am going to be able to adjust this pack to all sorts of trips. I can literally adjust it's volume down to a very small capacity and also be able to fill it right up. It seems like it will be quite sturdy enough to pack up a full 60 liters. Right now it feels very comfortable, I am sure once I wear it a while I will have to make some adjustments. Already this is 1/3 rd to 1/4 the weight of my old NorthFace pack I am replacing. I am getting older and now more cautious about the weight I carry, this pack should help out a lot! I love Sierra design equipment!

Is there any schedule that M/L torso with M/L waist belt will be restocked again?

Asked by: ken93
Thanks for reaching out! That combination is currently unavailable with the manufacturer. And unfortunately we do not know when it will be restocked. My best suggestion is to keep checking back. Please don't hate us.

Is there a torso length and waist circumference size guide?

Asked by: Cacamik
Thanks for reaching out! Looks like we really dropped the ball on this listing. I will get that size guide added ASAP. In the meantime, below are the measurements: Torso Size S/M = 16" - 19" Torso Size M/L = 18" - 21" Hipbelt Size S/M = 29 - 32" Hipbelt Size M/L = 32 - 35" The size options are torso first and then hipbelt. IE: size option S/M - M/L correlates to a Small/Medium torso with a Medium/Large hipbelt. I hope this info helps!

Good day. Maybe the question is stupid, but I want to make sure that I understood correctly)) In "choose the size" first is the size of the torso and then the waist !? Thank you very much.

Asked by: oldRenegade
Hey there thanks for the great question. It is incredibly confusing but you are correct. The sizes are displayed 'Torso/waist' I'll work with our team to see if we can figure out a better way to communicate that. The Sierra Designs Flex Capacitor 40-60 Pack is somewhat unique letting you choose the size on both harnesses, it really helps to ensure a good fit on all bodies. I hope this info helps!
