Hyperlite Mountain Gear Porter 4400 Backpack Review

@Tom:

Doh, busted!

Don't hold it against me :)

I've learned a lot over the years. One of the major shifts I've made, especially as I've worn out more and more gear, is that I'm tired of wearing out gear.

I really like that there are more durable options than the old Whisper. Poor girl just didn't have any seam strength, they wear out quick.

Nice conversation piece, though, and while I used it, it gave me a lot of opportunity to tell people about what UL was all about.

But my style has changed through the years and I'm carrying quite a bit more bulk now than then – packrafting gear, photo/video gear, and I most often travel with others in a group style, so we have group gear to share, like big shelters and big pots.

A good review, Ryan.

I think that the seam failures you are seeing on the pack are related to the strength and type of the fabric. It appears that the seam is OK, but the fabric is tearing around the "score" line of the stitching.

The actual attachment (be it a seam, patch, strap etc) will always be a weak point in any sewing. Where you let multiple stresses build up in a single area, THIS is where a failure will occur. In this case the seam, a compression strap sewn into it, and it is used to hold a paddle: Seam + Compression + Mounting. Coupled with walking/movement and stresses from the inside (applied, perhaps, a bit unevenly,) this becomes a predictable point of failure. Lengthening the strap over the seam would eliminate this type of failure, in this case. Seperating the stress points is the same as distributing the load over an increased stitching area, in effect, strengthening the seam and strap/mount area with more stitching per inch and more fabric per ft/lb of stress applied.

The waist belt is a different problem. All of the above applies, but is accentuated by the "Figure 8" motion of the hips. As you walk, your balance shifts from left to right. The seam stress will roll from left to right, too…following your hips. With independent stays, (such as with the Porter or older Miniposa/Mariposa,) or with flexible internal frames (like the old Ghost,) this is pretty much accommodated by fabric movement. Both stretching, wrinkling and slipping contribute to following the natural walking motion of your hips. As weights increase, you find rigid frames need less rigid mount points to accommodate this. (My old training pack uses a 1/4" magnesium frame w/buckles to mount the waist belt. I think Gregory used large diameter rivets to accomplish this hip following.) I believe you have hit about the limit (with current technology) at 40-45 pound weight handling with rigidly mounted waist belts. I would expect seam failures for anything more. Your occasional "bail outs" for altitude ailing clients probably stressed these well beyond the 40-45 pound range, and, repeatedly with each step… Both types have their uses.

But I agree, this appears to be a good light weight pack, though the newer ones are 31.1oz, per their web site. I would miss the two lower pockets, though. My drinks have a permanent place there.

The water resistance looks really good to me. Spending as much time canoeing through the ADK's as hiking, I can really appreciate a highly water resistant, and, one that does not absorb water. My boat, paddle, spray deck and PFD weigh a bit more than 22 pounds. But rafting 300 miles, mostly across lakes, and other still waters through the Fish Creek Ponds/St Regis areas really precludes a pack-raft. Water is an inevitable companion.

Coupled with Phil’s review, Roman Dial’s and Andrew Skerka’s comments, this is one well reviewed pack.

Will the 3400 handle similar weights in the 40-45 lb range?

He Travis,

I have the 3400 Porter and the pack handles a weight of 40-45 pounds without any problem. Tested it several times.

I also wrote some notes about this pack.

How would you carry a wet tarp in a pack with no external pockets?

You lash it to the outside of the pack using cordage and the vertical daisy chains, and/or secure it to the top of the pack using the Y-strap.

Doesn't that defeat the purpose of not having external pockets? I thought the whole idea was that you don't have stuff that's hanging out.

Andrei,
Did you read the section on "The No-Pocket Controversy" in the review?

In some cases it matters, and in others, it doesn't.

HYOH and YMMV apply here.

"The frame being limber enough (or bendable enough) to accommodate the more pronounced longitudinal lumbar curvature of a woman’s lower back in the lumbar-butt area…"

"Longitudinal" rolls off the tongue nicely, but I think the curvature is more "latitudinal".

I did. I asked the question hoping that there would be a good way of storing the shelter inside that I just hadn't thought of, because I really like the pack otherwise. The section only discusses the design decision from a convenience point of view, which is not so much of a concern for me, whereas carrying a wet shelter inside the pack, in my view, poses some "functional" risks. I still think people like Ryan, who seem carry all of their stuff inside (for very good reason), must have found a solution to this problem, and I would just like to know what that solution is. The only thing I can think of is to pack all the sensitive stuff in waterproof stuff sacks, but that seems somewhat inefficient, since the pack itself is waterproof.

I'm a "pocket guy".

Fuel, wet gear, food for the day, "personal kit", spare clothes, stakes, water bottle, and more are all on the outside. I try to never open the main body of the pack during the day…to much risk For Me to leave something behind, not to mention trying to find that wind shell.

My wet tent goes under a lid (gasp) until I can dry it out. Then it goes back inside, on the top of everything else, because I want to be able to get to it first at night.

"Clean" is appealing, but I'm with Skurka on this one.

I am too, currently. But I would like to become a "clean" guy, if I can figure it out :).

Waterproof packs are only waterproof until (not if) they get a hole in them.

Oh good, a "no pockets" thread. : )

I have no pockets and waterproof pack.

I keep wet tarp in 1 gallon zip top bag. Occasionally it leaks a bit but it's near bottom and anything below it is in a waterproof bag too.

I have a strap on top of pack, for compression, and occasionally strap wet tarp or jacket on top of pack held on by strap. Sometimes, it's so the wet jacket will dry out, more than keep pack contents from getting wet. If I'm packing in the rain, I'll probably pack up under tarp, close up pack, take down tarp, and strap it on top of pack, thus keeping contents of pack dry.

Thanks for all the replies, I have a better picture now of what a "clean" pack actually entails.

I asked HMG a query via email but they are a bit slow in responding, so I'll ask it here too….

I have seen HMG's recommended pack fit procedure, but I was wondering about back panel lengths between pack sizes. I have seen a small Southwest pack, a medium Ice pack, and medium Porter 4400 in person. The small SW had a distance of 18" from the shoulder strap attachment point to the bottom of the hip belt/lumbar pad. The same measurement on the medium Porter was 20". Is it safe to assume this back panel length measurement increases by 2" as you go up in pack size (i.e., the large would be 22" and the tall would be 24")? Does someone have a size large or tall handy they could hold a tape measure to? The stock hip belts and lumbar pads are all ~4" tall, I assume.

Was there an upcharge for customization (an extra strap sewn on, or making a modular hip belt-lumbar interface)?

TIA

I am a new owner of the HMG 4400 Porter, but I talked to Mike for him to make a modification. Mike designed a pocket mesh in the front. For me it is important to keep the wet stuff out on a pocket mesh, but also the Daisy chains are importants where I can tie more things in my trips with Packraft.

It looks good. How come your pack is black? Did you dye it yourself, or is this a new option from HMG?

A mesh front panel pocket really adds a lot of volume and utility for little weight. I stow my sit pad and rain gear, ready for instant use without opening my pack and pawing through everything. I do like having a buckle at the top.

The No-Pocket Controversy

"For me, perhaps, I grew up toting around single compartment rucks with nothing more than ice axe loops and the occasional top lid (which I often cut off, finding that it interfered with the ability to secure a bunch of gear under the climbing rope strap). I’m a huge fan of this very simple and aesthetically clean approach to wilderness packing." RJ

So you guys aren't to only ones with a new pocket…

Chase Jordan likes them too.

The black color is an option you can to ask HMG, this will be available soon on its website.

The black cuben is stronger but is 10% more expensive

HMG has the option of pocket stuff but I think that the mesh fits better on my necessities because is more simple, less weight and I always use it in my trips.

Cheers

To answer my own question, I am posting the response I got from HMG on the distance between the top shoulder strap attachment point and the lower edge of the lumbar pad/hip belt:

Med – 20 1/4"
Lg – 22 1/2"
Tall – 23 1/2"

I have a black pack and hate the color. Not because I don't like the color black; but because a black pack makes it harder to find things inside. Especially in a low light situation. Or in a bright light situation for that matter.
