Description

The G4™ Ultralight Backpack is one of the "granddaddies" of ultralight packs. First designed in 1998, the free downloadable instructions have been used by hundreds of do-it-yourselfers, making it the all time most-requested pattern from Quest Outfitters.  The pack features a detachable hip belt to better fit more folks and to increase the carrying capacity of the G4™ without adding weight. The G4™ is designed to effectively incorporate the "dual use" technique of ultralight backpacking. Your sleeping pad  becomes the pack frame by inserting into the back of the pack. ( We recommend the Nightlight Torso ) This way it can be extracted during rest stops to sit/lay on without unpacking your pack.

The bottom of the pack "flares" out to provide more area for your sleeping bag to minimize loss of loft from overstuffing. The HUGE side pockets will hold, as an example, two 2-liter soda bottles on EACH side! A generous mesh pocket on the back of the pack gives you a place to put sodden items where they won't dampen the other contents of your pack. Multiple lashing straps allow you to hang socks out to dry or secure loose or wet items onto the outside of the pack. A top lashing strap helps secure a rolled sleeping pad or similar gear to the top of the pack. Most common bear canisters will fit in the pack horizontally.

This pack is recommended for loads of 30 pounds or less.

I just received my new G4 in black and its perfect. Its going to replace my DIY pack I made 20 years ago. Thanks for the simple, useful design.

I've only used it for hauling items home from the library an grocery store, but have plans later this winter for a ski trip to the BWCA and a spring thru hike of the superior hiking trail. (Posted on 12/22/14)
New Black G4 vs older G4's?Review by Darryl
Quality

I just received my all black G4. I have 2 others (dk green) that I bought within the last 4 years that I just love. I also own 2 of the older & lighter Mariposas. Black looks really cool but I noticed that this newer pack does not have the Velcro shoulder straps that allows the user to add more padding like my other G4s. Not so sure I want to take this newer pack on a trip now as I am a older guy and do like the option of adding additional padding. (Bubble wrap). I also don't see the "made in USA" tag as on my other G4 packs so maybe the manufacturer has changed. Still a very good pack and the value is great but maybe no longer a tremendous value without having the ability to add padding and maybe not made in the USA?. (Posted on 11/28/14)
Best backpack for a small kidReview by Kai

My 71 lb 12 year old son is determined to through hike the John Muir Trail this summer and while he has lots of experience backpacking since he was 5 this involves a long carry between supply. His old pack just can't cut it. Since I am a happy user of the Mariposa I started looking for a small high capacity pack for him at Gossamer. At first it looked hopeless to fit his 13 inch torso (barely) and 23 inch waist but with some thought we tried the G4. What a great choice. Using the sit pad and lightly inflate his ground pad the small waist strap closes just fine. Took it out for a pretty rugged 20 mile overnight outing and the pack worked great. The hike involved trail, cross country and a couple of miles through a major burn out with lots of burned down trees to scramble over our under. Nothing ripped and pack was really stable. He loves the pack. If you have kids who are hard to fit and need capacity this it the pack for them. (Posted on 4/13/14)

The "standard"; can't go wrong with this one but there's a few downsidesReview by Gideon

Firs off, I'm an ultralight hiker; the GG Murmur is my main 3 season pack but I needed a winter pack that was still an ultralight pack. The G4 fits this bill and it's a simple, straightforward workhorse. You can't go wrong with this pack, however...

There are a few minor issues I have with this pack.

First of all there's no place inside the pack to secure a small stowage sack; no little loop or place to clip to. Secondly, the shoulder strap's are a bit too short. When stuffed with quilts for hammock camping I was at the full length of the shoulder straps. It's a bit different how they go to the outside bottom edge. So when the pack is full it makes it too tight/short. Weird how there's a buckle and clip on the ends of the two shoulder straps; seem odd and almost as a means of keeping the straps from pulling through the buckle. I'm a short guy using the medium size and have to figure out how to mod the shoulder straps so they're long enough when I'm wearing my winter gear.

Finally, I hate the separate waist belt pockets. The move too much and fall towards the buckle; go with out them or figure out a way of securing them to the waist belt so they don't move.

So, all in all a decent pack but I think there are much better ones out there!

SIDE NOTE FROM GG STAFF : A velcro tab is located on the hip belt pockets that attaches into the the velcro on the belt - if attached the pocket will not slide (Posted on 2/9/14)

I've owned my G4 for well over 10 years and it's never let me down. It's been to the top of Kilimanjaro and 3 weeks trekking in Africa, trekking through Alaska, as well as many many backpacking trips. I've over loaded it too many times and not one ripped thread. (Posted on 12/14/13)
G4 pack FTW!Review by Frank Patriot

The G4 was my first ultralight pack. I switched from a 65L Sierra Designs pack to the G4, which saved me around 3lbs just on the weight of the pack itself. I was amazed that I could fit all the gear into the G4 that I could fit into the big huge SD pack. I really like the big mesh pockets that wrap around it. There is no top lid, so I really have to take care in closing the roll top correctly. You definitely want to grab a pair of GG pack liners to use, to keep your gear dry. There are small loops on the back for looping the shock cord that is included, which is so handy to have in case you want to stuff a piece of clothing in there and let it dry out as you hike. I wasn't sure how I'd like the frameless construction, but if your gear weight is reasonable, it's just fine. I cut a section of my Thermarest RidgeRest foam pad off to use as a camp seat and also, it fits inside a dedicated mesh sleeve to give the pack some shape. If you remove your sleeping bag from the stuff sack and just cram it down into your pack, it will give it some shape, too (again, use a pack liner). Also, I kinda missed all the little hip belt pockets that were on my SD pack, but fortunately, Gossamer Gear sells some hip and shoulder strap pockets that you can use to pimp out your pack. I grabbed one to keep my Sawyer min filter, headlamp and a snack into. I love my G4, and recommend it to everyone I know who doesn't have one. (Posted on 12/11/13)

Great value and quality. Stuffed it, fell on it, dragged it through the White mountains. It's not designed to last forever. Will buy another just like it for the PCT. (Posted on 10/21/13)
The BestReview by Sierra Pete

Bought this on sale some time ago. I was looking for the lightest pack that I could use for a week long trip in the Sierras. The G4 worked perfectly. I was a bit concerned about how comfortable it would be and how well it would transfer the load to my legs (vs. my shoulders), but it was as comfortable as any backpack I've used. I was also concerned about durability, but after my trip I realized that I'd much rather have a light pack than one that lasts for 20 years, and I had no problems with rips in the light fabric or even the exterior mesh. It's a great pack. (Posted on 10/3/13)

I originally purchased a G4 in 2002 to give to my son for Christmas in preparation for our trip the following summer to Philmont Boy Scout Ranch. I liked it so well I purchased one for myself. It's been on three 10-day hikes through Philmont along with many other trips. It's light weight, well made, but you can't abuse it by sliding it along sharp rocks, sitting it against a thorn bush, etc. I've carried up to 45 lbs in it with no problem. I'd get another one.

I did a ton of research before I bought this pack. I was looking for the cheapest option that was also ultralight. This pack delivered on both of those scores admirably. I was worried that it wouldn't be durable, but so far it has held up well. It's not the most durable pack in the world, but you can't expect an ultralight pack to be super-industrial-heavy-duty. But, I've been very happy with its durability. No rips or cuts at all so far, even on the net pouch which I thought surely would rip when I stuffed Mountain Home freeze dried pouches down in there with their sharp corners. (Posted on 7/2/13)

I have used this pack on several dayhikes and a few overnight trips in the mountains of New Hampshire and Massachusetts. It is without a doubt the most comfortable pack I have ever used ! My load outs are usually 14-18 lbs. The simple ,no nonsense design is just wonderfull.I also ordered a size medium hip belt pocket that is awesome. (Posted on 12/3/12)
