Does anyone know what diameter the side compression cord is and/or what the lineloc is? It looks like the cord is 2.5mm and a lineloc 3.
Yes that's correct. It's a LineLoc3 with 2.5mm.

Sadly I purchased this at the pre order price of 150, and now am told its going to be delayed in shipping and it gone on "sale". Hey Drop what's the incentive to pre-order?

I contacted support and asked for a price adjustment. They gave me a refund for the difference if that helps!

I cancelled and repurchased. :)
Well, it's that time of year, (November 2020), when we start to see the Black Friday type of sales, Markdowns, and Deals! Many of us could be looking to purchase new outdoor gear, or perhaps an additional Backpack to add to our gear arsenal. I'm looking at three backpacks... 1) The Gossamer Gear Mariposa 60, made from durable 100 and 200 Denier Robic Nylon, weighing in at less than two pounds. https://www.gossamergear.com/products/mariposa-60-lightweight-backpack 2) The new Outdoor Vitals Shadowlight Ultralight 60 Backpack, also weighing in at less than two pounds, and made from 100D Robic Nylon w/ 200D Spectra Ripstop & 210D Robic Nylon w/ 400D Spectra Ripstop, and a Water Resistance WP Rating of 1500mm HH. https://outdoorvitals.com/products/ultralight-backpack 3) The Drop 40L Backpack designed by Dan Durston, also weighing in at less than two pounds, and made from Waterproof Dimension Polyant VX21 and VX07 X-Ply fabrics. https://drop.com/buy/drop-40l-backpack-designed-by-dan-durston?utm_placement=0&referer=TZUUQ8&mode=guest_open&utm_campaign=Automated%20Daily%20Promotional%202020-11-18&utm_source=SparkPost&utm_medium=email&utm_term=Daily%20Promotional&utm_content=1605689527974.131998824686880894366550#overview According to my basic research, VX21 and VX07 are actually referred to as X-Pac fabrics, and VX21 is a laminate fabric comprised of the following layers: a C6 DWR 210D Nylon face, Black Polyester X-PLY at 22 degrees, 0.25 mil PET film, and a 50D Poly Taffeta backing for abrasion resistance. It is interesting to research, and to see just how far modern (space age) backpack materials have come from canvas, and nylon Cordura. Extremely light, and extremely durable too! I have to say that I am leaning towards the larger capacity 60L packs, as the weights are the same, despite the capacity differences between the Drop 40, and the Mariposa 60, and the Shadowlight 60, and I like the colors better on them too. Costs are as follows: 1) $202.50 for the Gossamer Gear Mariposa 60 on sale now. 2) $150.00 for the Outdoor Vitals Shadowlight 60 on pre order now for their OV Ultralight Members. Note: I have a $40.00 credit, or balance with them now, since I joined their $10.00 per month OV Ultralight membership plan, so my cost after using my credits would be $110.00. 3) $120.00 for the Drop 40L Backpack designed by Dan Durston. I know that Dan will probably want to comment on this, and that is fine, as I would expect Dan to be proud of his design, but I would also like to hear what you other guys and girls think about my choices, and I would love to see some comments about the materials and fabrics used to make these different backpacks, especially from those with actual hands on outdoor use and experience.

I'll get things started with a few comments. 1) Indeed the weights are all fairly similar despite different capacities. That's because most of the weight of a pack is in the frame/pockets/straps/hipbelt whereas the actual size of the bag doesn't affect weight that much. You can see that with the OV packs where their 45L and 60L versions are only 1oz different. If you sometimes need a 60L pack then it would make sense to opt for that, but it has downsides too where an excessively large pack isn't as nice to carry since it's bulkier. 2) Note that the rated capacities of backpacks can be wildly misleading because there is no standardized way of measuring. For example, you'd think the Mariposa 60 is a much larger bag than the Drop 40, but it's not. The Mariposa actually has a 36L main compartment and only gets to 60L by GG counting how much they can stuff into the external pockets. Only a few companies do that (ULA being the other notable one). Like most companies, we rate the Drop 40 based on the only the internal volume (33L + 10L in the roll top) so the internal volume is roughly the same as the Mariposa. We haven't counted the external pockets because it's a grey area where the volume really depends on how much you stretch things out, but these two packs are fairly similar in size. 3) You are correct about the X-Pac fabric. Traditionally packs were made of nylon with a PU coating on the inside for waterproofness. The problem with that is that the PU coating routinely degrades/flakes/peels after a few years of use, so it's not reliable waterproof. Thus, while OV says the Shadowlight is 1500mm waterproof, it won't actually be waterproof during normal use. It will be at first, but even in the first season you'll likely see it leaking. Conversly, X-Pac has an actual layer of plastic inside so the material will basically never leak. You can get water thru the seams (you can seam seal) but it's far more waterproof to the extent that I use it without a pack liner even in steady rain, and there's only minor water inside. I handle that by having my essential stuff (e.g. sleeping quilt) in a silnylon dry sack. 4) Besides the X-Pac fabric, the unique thing about the Drop 40 are the pockets that give you quick access to your stuff. All these packs have hipbelt pockets but the Drop 40 goes further with shoulder strap pockets (e.g. phone, sunglasses, sunscreen) and the zippered side pocket that lets you grab larger stuff like hats, mitts, maps etc without taking off the pack.
Wow! Great concise and informative reply. First, and yes, a smaller pack has its place, especially when you don't need to carry a lot of gear, or like when it is warm, or just out on a day hike. That is why I have different sized of packs now. To be fair to the Gossamer Gear Mariposa 60, it has always received mostly 5 Star reviews, and high praise, even at Backpacking Light where Dan is a contributor, and at many other review sites. Some people like the myriad of pockets, (6 or 7, not sure), so they can organize their gear better, or at least to separate, and organize it the way that they want. The larger pocket on the left side is a great place to store a tent that might be wet, so you can easily carry it, but you do no have to put it inside you pack. When I worked as a Ranger in Alaska, I was always trying to figure out the best way to wrap up, and store my tent that still had some moisture on it from the night before, so that the dry inside part of my tent would not get wet. Luckily I was mainly traveling by Kayak, and could just shake it off, fold it so that the innr stayed dry, and then to put it in a bag, and then stow it inside one of the compartments. No pack was involved. Anyway... The waterproofing, or at lest water resistance pf the X-Pac laminate is definitely a plus, as it is evident that it would be hard for water to pass through the sandwiched layers. Of course, a pack cover, trash bag, or a dry sack as Dan noted solves those type of problems in most cases, and there are different DWR products, and other water repellent products that could be applied if desired. All great points! After reading Dan's response, I might have to purchase all three packs! LOL If only Dan's tent only came in OD Green, OCP, a/k/a Scorpion 2 Camouflage, Multicam, or even better Vietnamese Tiger Stripe Camo pattern!

Which bear cans will fit in this? I'm pretty sure the Wild Ideas Expedition won't.
I'm not entirely sure. I know many people are using the BV450. If you look at the measurements of the bear can and of the pack, you should be able to tell:
The Wild Ideas Expedition is listed at 9" diameter and 14.5" tall. A 9" diameter equals a 28" circumference, so that would fit vertically in the pack. It would not fit horizontally since it would be (9" x 2 + 14" x 2 = 42" circumference).

I've had this pack out twice now and it's darn near perfect. The one thing I'd like to add is a set of straps at the bottom to carry my tent. I tried using a couple of shock-cord loops but the tent bounced around too much. I'm considering sewing a couple straps onto the lower part of the daisy chain - has anyone done this and willing to share some pics? Thanks!
Nov 6, 2020
Thanks for the ideas, Dan. I probably do need to re-think my packing strategy.
Nov 7, 2020
I’ve always liked to have the option to carry something attached to the bottom of the pack. I’m seeing a newer to me trend with stretchy material acting as a kangaroo pouch . That could work here too maybe. As it stands, I find the pack a perfect size for my style of outings. ~RL

Just make a true Large already!
Nov 16, 2020
Agreed! I'm right on the boarder and the load lifters are basically useless. Short hikes are fine but longer ones I start to feel it. I'd buy a Long version in a heart beat!

Hi. I was wondering what the height of the pack is. I am wondering if the overall height is small enough for european carry-on...which is , i think, 21 inches. Usa domestic carry on is about 22 inches. Anyway ...just wondering!
The height of the frame is pretty much right on 21". It fits in USA carry on for sure, provided the pack isn't stuff full higher than the frame. Unsure if it fits on European carry on - it would be close.
Is there a way to jeri rig some 20 ounce Smart Water or Gatorade bottles onto those front shoulder straps in their mid to upper region? Do you think water bottle/water weight in this area is a bad idea for spine /shoulder ergonomics? I can always use the side pockets on this pack.

It has been done. Check out my review (from back in June?)for more details.

Will do. Thanks so much.

Hey Dan, I am a little confused on how the put the frame back into the backpack correctly. Does the bigger bend face towards your back or away from it?
You want it to bend in to your lumbar area.
