    Description on Durstongear.com

    Very interested in the material, ALUULA Graflyte™, and construction “heat bonding and laser cutting”.  30L is too small for my use case(s), but I’m certain it hits the spot for a lot of people.

    The total volume is (M/L) 46/48 litres with the external volume for comparison, since some other brands count those in the total. So it might be bigger than the 30L sounds.

    Looks like a worthy competitor to my ZPacks Nero 38L

    My video provides a lot of detail for the pack including a lot of info on the new ALUULA fabric (a lot more than on our product page):

    YouTube video

    The fabric is really neat. It was just released today at the ISPO show in Europe and lots of companies are interested in it. Alpacka and Arcteryx and showing off prototypes at the show.

    I can’t find sizing information for torso or hipbelt sizing; where is that on the site?

    When I’ve used dynema, after a year the waterproof layer delaminated

    Do you think ALUULA will be different?

    Jerry he addresses that in the video, also Ultra has been doing a pretty good job of not delaminating. Bought mine this morning. Stoked.

    Excellent design and the material sounds awesome.

    The graflyte is woven uhmwpe heat bonded to polyethelene sheet (?).  There must be a very narrow temperature range combined with high pressure to do that without damaging the fibres.

    In the production process, I assume there is also a very narrow temperature range to weld/bond without compromising strength?

    The total volume is (M/L) 46/48 litres with the external volume for comparison,

    I noticed that, and it might very well handle the volume of my gear with occasional overflow under the top strap.  However my total pack weight is routinely in the 24-26 lb range and I think I really need a frame to make that all-day/multi-day comfortable. I’m excited to see where Dan takes his design ideas going forward as this pack is extremely attractive from both a technical and aesthetic standpoint. And as usual with Durstongear the price point is very good.

    Nifty. Now make a light weight framed version with load lifters and we are talking!

    ahhh…

    I think the dyneema I had that delaminated was mylar

    Maybe the polyethylene is better

    Thanks everyone for the kind words.

    With regard to delam, any other composite material is held together by glue, which can work well but also the glue can fatigue. Whereas with ALUULA there is no glue but it is somehow fused/melted at a molecular level (this is ALUULA’s special process) to essentially become one.  It’s still a new material so only time will tell but it sure seems very robust to delam. The film feels like melted right into the weave where I can’t see it ever peeling off. Also they have been using the since same process with other ALUULA materials for quite a few years now and it has been working there.

    “I can’t find the sizing…where is that on the site?”
    At the bottom of the page are several tabs. The one called ‘specifications’ has the sizing info.

    All the attachment points look great, as do the front and bottom pockets, plus the cinch cord on the (same size, nice!) side pockets. I like it all except the shoulder pockets but that’s because they don’t work well with the soft flask bottles I use. Are the shoulder pockets the same size as on the Kakwa or has it become less tapered at the bottom? Tough to tell in the pics.

    Thanks Charlie. The shoulder strap pockets are wider than the Kakwa ones because they extend to the edges of the strap, whereas the Kakwa shoulder straps use edge binding so you lose about 10mm of width on each side. The width of the pocket is about 55 mm on the Kakwa and 75mm on the Wapta (so about 2 1/8″ versus 3″ wide). So these are 35-40% wider through the length of them.

    That makes sense, I see the difference in this edges of the shoulder straps now…. and so we just need to add the weight of the Kakwa frames plus a couple ounces for the extra material and that’s what we can expect the next line of the Kakwa 40/55 to weigh?  :)

    I see dimensions for circumference but can you share width/depth numbers for the body of the pack please?

    Nice pack! I’m exited about the design direction this pack and the new material are leading the industry into. Kudos to Dan for once again being such a force of innovation.

    I love all the attachment points and it’s great to finally see a bottom pocket out of durable/non stretch material (I’ve been surprised nobody has done this until now, it really seems like a no brainer). Also the single pull top  strap seems like  such an elegant and user friendly solution that in retrospect it makes one wonder how this has not been done more.

    Dan your shoulder straps look great but personally I’d love to see an option for running vest style straps on something like this pack , you could even add some more attachment points so the straps could be swapped out giving people the option and  if you had multiple tiered attachments you could have some adjustability in the torso length.

    Like others have said it’s going to be awesome to see this  material and these design elements hybridized with the kakwa , also I think a minimalist frame design with say a 35 liter version could be interesting.

    -cheers

    I’m curious what the cost of Aluula is by the yard over Ultra or DCF, I assume it’s quite pricey

    “However my total pack weight is routinely in the 24-26 lb range and I think I really need a frame to make that all-day/multi-day comfortable.”

    Durston lives in the PNW where bear canisters are less required–or were, when I lived and hiked there. I like to use a Bearikade Scout, on 4-5 day trips, in part because it fits so easily horizontally at the bottom of a pack. But most canisters are larger than this. Partly because of the need for a canister, on a six day trip, my starting weight is also about 25 pounds. The geometry and hard sides of canisters require large-ish pack volume to comfortably carry. (I can’t stand trying to carry a bear canister up top, even when empty.)

    All UL frameless packs don’t address this issue, IME. I wonder if packs have to be designed around the fact of having to carry a bear canister in order to start to answer the issues they bring up. They aren’t soft; they don’t compress; they don’t adjust to load–just the opposite. Load has to adjust to them. And to be fully and easily functional, a full 5-7 day or more load of food has to be inside of them. Even with a Bearikade, you have to add a couple of pounds to your base weight when using one, or more with other canisters.

    For me, this required a frame pack in order to keep the load on my hips and the canister off my spine or back.

    geeze, thread drift here, sorry! Dan’s pack looks awesome. I use a Schnozzle as a dry sack, and so don’t worry about wetting out my pack contents. But of course rain adds weight to absorbent pack fabrics, so a durable waterproof layer would be a good advance.

    This material seems perfect for an UL ski/splitboard pack, I’d like to see one made  with similar style attachment points for multiple ski/board carry options that would have quick access sleeves on the perimeter of the back panel for your shovel handle and probe this would be to utilize them as the frame structure terminating at the hip belt. Also multiple access options into the main pack body , back panel access  being  a must.

    If only I had the ear of a backpack designer who would be capable of executing such a thing…….

    “can you share width/depth numbers for the body of the pack please?”
    At the bottom the pack is 29″ circumference. The width/depth can vary since neither is defined by a frame but typically it’s about 10″ wide and 7″ deep. You can put a 12″ long tent in the bottom and then the depth is more like 6″. The hipbelt connects to a 6″ wide sleeve, so the fit isn’t really affected as the shape of the main compartment morphs.

    Up top the circumference is 35″ which tends to be about 13″ wide and 9-10″ deep but those also can trade against each other, although not as much because the shoulder straps hold the width at close to 13″.

    “personally I’d love to see an option for running vest style straps”
    Yeah that would be cool. It’s not in the works but would be nice to do eventually.

    “I’m curious what the cost of Aluula is by the yard over Ultra or DCF”
    It’s early days so the cost may change over time (e.g. improve). I’m not able to disclose pricing specifics but it’s definitely a premium material. By the pricing of our packs you can probably guess it costs more than Ultra or DCF.

    Locale: The West is (still) the Best

    It’ll be interesting to see how the new fabric compares to Ultra-X and the like.  Are there any abrasion studies? (think previous fabrics were tested by dragging a sample behind a vehicle).  Read elsewhere the fabric is UV-resident and “waterproof”.  It’d be nice to compare..

    total volume is (M/L) 46/48 litres

    That is pretty good. Barely adjusting to a 35L (50L total) pack for 4-5 day load outs,  using an accordion foam pad for back ventilation,  but I like the ventilation pads on this new pack.

    bear canister

    Think it’s the circumference a pack can take.  I’ve read trip reports when some (not all) packs down into the mid 30L-ish can carry a BV 450 to 500.  May not be a lot of space left inside though.

    Abrasion on UltraX is excellent so it can be a bit of a moot point but ALUULA Graflyte V-98 that we are using is about 50% higher yet for ASTM wear cycles.

    Sweet looking pack.  I don’t have a smaller volume pack for shorter trips, so looks like this is on the top of my “small volume pack” list.
