Product Description

The Mariposa™ Plus continues the ultralight backpacking revolution with the same incredible array of important features at a weight of just over a pound! This is the same great pack as the original but constructed of ripstop nylon for added durability while keeping the weight penalty to about 3 ounces. We've also made the side pockets bigger and beefed up the interior stay pockets to make them more sturdy. For those of you who prefer a more "stealth" color scheme it comes in a light Sage.

The only change for 2011 is the new aluminum curved stay that replaces the two carbon fiber straight stays. This new feature greatly improves the fit and comfort of the pack. It also increases the load transfer capability and allows the pack to hug your back better providing a snug fit and virtually eliminating the need for load lifter straps. This single enhancement, we believe, make this the perfect all-around pack. You won't believe how good this pack feels with this new stay until you try it. The approximately 3 ounces that it adds won't even be noticed.

We have also changed sewing contractors for 2011 so you will notice higher quality sewing, more consistency, better craftsmanship and more reinforcement areas on all of our products without adding any weight, and in some cases even shedding weight.

We feel that the 3 different pack sizes together with the 3 removable hip belt sizes gives the customer the ability to customize his or her pack in order to achieve the best fit. We have often heard from women that our packs are too large for them so we've resized the packs and now have a true "Small" pack size. This pack will also fit younger hikers allowing kids to "see the light"! This system also provides thru-hikers the ability to utilize two different size hip belts on those months-long, weight-shedding long distance hikes. A hiker could start out with a larger hip belt and then mail the smaller one to a mail drop up ahead on the trail when they feel they will have lost enough weight to justify the smaller belt. No more field sewing of the hip belt with floss to make it fit better!

The Mariposa™ Plus continues building on the popular features of the stalwart G4™ backpack, effectively incorporating the "dual use" technique of ultralight backpacking. Your sleeping pad (NightLight™, Z-Lite™/Z-Rest™, Thermarest® 3/4 length, or other 20"-wide pad) becomes part of the pack frame by inserting into the back of the pack. This way it can be extracted during rest stops to sit/lay on without unpacking your pack. The shoulder straps and hip belt are designed to accept unused articles of clothing as padding. Foam inserts are included if you don't want to use sleeping socks, gloves, etc as your padding. Both side mesh pockets are deep enough to swallow a 3-liter Platypus®.

The Mariposa™ Plus utilizes a new aluminum rod curved single-piece stay for real load transfer (removable for lighter loads), a unique asymmetric side pocket design (right hand pocket is accessible while wearing the pack), a dual function removable and adjustable sternum strap/emergency whistle and a hydration bladder pocket with ports on each side. Cushy wicking fabric on the shoulder straps and hip belt prevent slipping and the 3-dimensional weave aids in faster drying times. Multiple pockets help you organize your load. Tons of strategically placed lashing loops enable you to easily adapt the pockets to carry longer items by lashing them to the sides. The unique "Y" top lash strap allows for a more stable 3-point connection to secure items such as rolled sleeping pads or bear canisters with still only one buckle to operate. The sturdy shock cord compression lacing allows you to reduce the pack volume so it still carries the load tightly for shorter trips. Many of the features are removable, so you don't need to carry the weight if you don't require that feature for a particular trip. You can configure the basic pack, with sternum strap and curved stay, for a little over one pound.

You'll love the attention to detail such as the angle on the bottom right pocket to make it more accessible, the use of "V" lash loops to spread the loads over a wider area and for ease of use, and the lining of the shoulder strap and hip belt with silnylon against the wicking fabric, for easier insertion of socks, etc, and to help prevent those socks from getting soggy from sweat.

IMPORTANT NOTE: The shock cord does not come pre-installed in the loops, but we have included the shock cord with two cord locks for the customer to place where they need it most. This gives the customer the option of cutting the cord into two pieces and using it on the sides of the pack to compress the depth of the pack.

All Mariposa™ Plus backpacks ship with the following:
Aluminum curved stay
2 foam hip belt pads
2 foam shoulder strap pads
120" of shock cord and 3 mini cord locks.

"I had the opportunity to take my Mariposa with the new curved aluminum stay on a 3-day 37-mile trip through the Cohutta & Big Frog Wilderness areas last week. The new aluminum stay is wonderful - a tremendous improvement over the straight arrow shafts. You have consistently provided excellent gear and outstanding customer service - I really appreciate you, your products, and your service." - Jim Moore

"Like I mentioned on the phone, you helped to keep me on the trail into my sixties (I am now 62). Three years ago the old body just gave out while humping over 60# on a 3 day desert backpack trip with my son. It was at that time that I discovered Ultralight Backpacking and its related gear ---after much research I decided on Gossamer Gear for my pack (the Mariposa). With your new hip/shoulder pad pouches my pack is complete. My Base Weight is now about 8.5# on any given trip, and I hike the kids into the dust (including my grand kids)." - Steve Dennstedt | Sgt USMC 1965-1971, Vietnam 1967-1968

"The pack felt great and I am so pleased with it that I am probably going to use it on most of my planned backpacking trips this year when I’m carrying 25 lbs or less. Width-wise, the main compartment on the Plus is narrower than my other main pack and it felt like this translated into much better load transfer to the hips." Read Full Review
