I hope it fits, and I hope I like it, because I just joined, wheeee! I'm 5'3", followed the Zpacks fitting video, and self-measured at 18.5." I bought the small frame, with a small hipbelt. I measured ~32-33" around, going over iliac crest. I'm wondering if I should buy any additional accessories from the Zpacks site? Thoughts?

I’m a tad over 5’3” but my torso comes out around 14.5” so never can find a pack that works. Do you have super short legs? Mine are a little long for my body but not 4” longer to make up for your 18.5” torso so i’ll be really interested to hear your feedback after you receive your pack and wear it full? I’m still messing with my ULA circuit. My old heavier Deuter ACT lite SL fits perfect, unfortunately so i light need to go back to it. .

A pair of pants I like to hike in are 29" inseam. When I measure my body, it's more like 27.5" - 28.5" (I'm not great at measuring hehehe). I'm 39" from my natural waist to the floor (I marked the wall next to my natural waist above my hips, then measured from that mark on wall to the floor.) I had my roommate measure my back following the REI video instructions, and I come out to 16.5" - 17". I'm about 29-30" circumference there (waist is 26", about 2.5-3" above REI measurement location) so it's a higher measurement point than the Zpacks instructions. I'm rockin' a decent amount of fat right now, so it makes measuring iliac crest tricker than when I'm thin. I'm really not sure if this pack will work or not, but decided to risk it. There is the Scout on their website that I was also considering. I can always sell this one if need be. My two previous packs are a 2009 Gregory Women's Jade 50 size XS and a 2017 Gossamer Gear Gorilla size Small, Hipbelt Small. That Gossamer Gear hipbelt was way too small! Their website says, "Small hip belt (24" - 34" waist) (61 - 81 cm)" My waist ranges from 24.5 - 26.5." No where close to the maximum end of their waist range. My hips are 34.5 - 36.5" I didn't realize it was men's sizing, since it didn't say the Gorilla was a man's pack. Won't shop there again, that's for sure! (Missing stitching didn't help my opinion of them either..) Two years later I'm still pissed off... and two years later they still have men's sizing in a supposed unisex pack. OK /end rant I'll follow up here once I get the Zpacks backpack, and let you know how it fits me.

Can anyone speak to the internal volume of this pack, compared to the ULA Ohm? I pretty much max out the volume of that pack on some trips, so I wouldn’t want to go smaller.

I'm surprised at the number of people willing to pack their bear canister upright. Seems like a nonstarter for me. It would seem to be to often too unstable on end like that. Do others have favorable experience with canisters packed vertically/on end like this pack requires?

I have packed a backpack with the bear canister both ways over the years. I find my pack sits better on my back with the canister vertical, keeping the weight closer to my center of gravity. With the canister sideways it put more weight to my sides. On a rock scramble it is harder to control like that. I guess it's a personal choice. I like to stuff my lighter stuff down the sides keeping the heavy gear in the center.

Hey, at only $0.57 a gram shipped for a M/M how can you go wrong (MD forgot to add the 42 gm for the two pockets) ? But seriously, if you want this pack, for this season I don't think you'll find a better deal. Money saved is money saved. If you can wait for Christmas I think you can get 10% from Zpacks. I've had an Arc Zip for a few years and I love it. For me, definitely worth the dollars.

The last Black Friday they had was for the pack at normal price with free strap pockets (I think). It was a savings of $50 but only available after the season ended. As you say, this is before the season really starts and is some savings. Could it be more, yes. Why would it be though? Demand is only going to increase as we get closer to June-October.

WOW! $355 after shipping - a whole savings of 5%. They couldn't even get to the 6% of sales tax for my state. This is a JOKE! A savings of $20. The cost on the website is $375 with pack and pouches + free shipping. I am sorry to be the one who keeps saying this, but I am ready to stop the whole Massdrop membership. The savings is pathetic from when it first started. this is getting to be simply access to my interests from companies shopping their products.

I agree in this case, Zpacks is probably not the right value proposition for Massdrop. They are going gangbusters on their own - they don’t need to discount for anyone. Why would they offer Massdrop a big discount?

I was amazed at the listed weight and surprised the frame material wasn't listed anywhere, so I sleuthed it out. Carbon fiber.

Bear can - required in sections of California so it would effect those doing the JMT and for a portion of the PCT so its a consideration for those hiking those areas.

It can be a real problem to figure out how to strap those bear canisters onto your pack. They often don't fit inside the pack so that is a real selling point.

I've had my Blast 3 years now. Light as a feather and tough. I carry 8.2 lbs plus 10 liters in a bladder for extended desert trips. No problemo. Use the sizing chart by Zpacks. There is quite a bit of adjustment either way. Get it!

Question: does anyone know if the pack in XS and short might fit a woman who is 5’4” and narrow shouldered? Male set standards would be uncomfortable.

Height is not a good method of determining that. Measure your C7 vertebrae to your Illiac Crest (hips). Video on such here - https://www.youtube.com/watch?v=IwYSHHGqdh4 If you're under 18-19" in this measurement, you may want to consider the Arc Scout backpack instead, if Zpacks is what you're looking at.
Apr 14, 2019
For what it's worth, I just joined this drop and bought the small, with the small hip belt. I used the video alfredo posted, and measured about 18.5." Might not be perfect because I measured myself. I like to have my hip belt centered on my illiac crest. I am a 5'3" female. Hips are roughly 35-36", waist is probably 26.5" right now. I put on a Gregory pack, tightened the hip belt, took it off, and measured it. Roughly 32". I measured my waist/hip area where I want my hip belt to sit, and that was 33". The 1" difference is likely due to current squishiness (have 1.5 - 2" excess fat on waist). Hope this helps! :-)

You have to click on the "buy" button to find out your total cost. There is no obligation to buy doing this. However, if you are an international customer, there may be customs duty, taxes, handling charges, and currency exchange applied once it gets to you...

I get it but the purpose of Massdrop is to get a discount for buying in bulk. There's very little incentive to save $25 by buying this in bulk here. I know DCF is expensive, and that they have a rabid following but if they can guarantee a chunk of sales, that allows for great forecasting in the biz for a project like this. If the margins are so low that the reason they can't offer it less then that would be better for them to be more transparent, otherwise, the discount doesn't make sense to buyers. Basic marketing and sales is that confused minds don't make decisions, AND from a persuasion angle, context sets the frame. The positioning on this offer just isn't good. I'm sure the gear is amazing and I've trekked with friends that have this, just needed better positioning as to why it's still so high priced.

If anyone in California is on the fence about ordering this via the drop, the pack and 2 belt pouches is cheaper via the Zpacks website when you take into account CA sales tax and shipping. It's approximately $5 cheaper on their website.

Wow, first we saw the ULA Equipment Circuit Pack, now this!
+ You will never find much of a discount on Cuben Fiber items. + ZPacks has a pretty outstanding reputation as a company.
NOTE: This pack is made for the lighter side of backpacking, with a recommended max load of 30lbs, but does have plenty of room 45L+, the BearVault 500 will fit in the upper half of this pack standing on end.
Now if we could get some sleeping quilts in the mix! dro.ps/v/pQro9Lf
