Description

Description The Mariposa™ Ultralight backpack, is absolutely loaded with size, features, pockets, and new materials. Built on the same basic platform as previous iterations we have upgraded it for fit, comfort, durability, functionality, and feature set. The Mariposa™ is constructed largely of our custom 100 and 200 denier Robic nylon fabric for a sweet spot blend of toughness and weight. New for this model is a completely revamped unisex harness, which coupled with our new plush padded hipbelt with integrated pockets makes for a comfortable functional ride.

The Mariposa™ has 7 exterior pockets for loads of options for organizing and accessing your gear.

The Mariposa™ Ultralight is a top loader and utilizes our OTT™ (over-the-top) closure system for a simple, solid, secure closure that also includes our largest zippered top pocket. Inside the pack you'll find an updated version of our proprietary removable stay.

At just over a pound and a half complete, the Mariposa™ remains Ultralight to the core and is tougher and more feature rich than ever.

The Mariposa™ ultralght backpack is a LARGE volume pack that is suitable for most any type of backpacking trip.

The Mariposa™ is best with loads under 30lbs but will handle up to 35 just fine.

Great Transition to UL PackReview by BeeKeeper

This is my second Mariposa (4th and now 5th generation). Previously I had an adjustable off-the shelf big-box manufacturer pack, as well as a competitor UL pack. However, after receiving my GG Mariposa, I sold the competitor pack, and never looked back. The small fits my 16.5" torso just about perfect. The 5th generation shoulder harness is very comfy for my small frame. Hip belt and pockets are also a great fit. I have a severe sway back and having an adjustable stay has made a huge difference for me in pack fit and carry.

I love the large side pocket for storing my tent and ground sheet. The mesh outer pocket is great for carrying camp shoes or other items needed for same day. I don't use a stuff sack for my down sleeping bag and there is plenty of room for leaving it unfurled. Although it is rated to carry 30-35lbs, I most often carry around 18-22lbs.

This pack washes well. I just remove the stay and waist belt and throw it in my washing machine then hang to dry. It looks new after a good year of use, my gen 4 also looks new after 2 years of use. (Posted on 2/11/15)

First thing I notice when opening the box.... WOW this bag is much more durable and built much better than I expected it to be considering it's weight. Normally there's a trade off in quality/durability when you want something this light. Not the case here.

Second, Although I am 6' tall my back measures just small enough to fit a med. That doesn't bother me because I like the little bit lighter weight and to wear my pack fairly high on my back. Although the pack is VERY comfy the shoulder straps are extended as long as possible in order for me to wear it. I am thick in the chest, ribs, and shoulders so that doesn't help but maybe a little more room to adjust the shoulder straps would be nice... after all they do include a clip so you can clip the excess strap material together so a little more length wouldn't really get in the way... plus trimming excess strap material is easy if it is in the way but adding is impossible. If I were any bigger this bag wouldn't work for me because the straps are just that short.

All in all I love this bag. It's insanely comfy when you use a sleeping pad as your back rest but also keep in mind if you sweat your sleeping pad will get wet and you must dry it before you sleep on it. The pockets are huge and the mesh is MUCH stronger than one would expect. Besides the short shoulder straps (for my big frame) I have nothing to complain about. Easily the best bag I've worn.

I'm 6' 215lbs I bought this bag with my own money and was not asked to do a review. This was done simply to help others make informed decisions. I have one trip on this bag so far but will be doing many more. I will continue to update my review if anything changes. NOTE FROM GOSSAMER GEAR : It is Very possible this customer would be better suited in a Large Mariposa at 6' tall. (Posted on 1/20/15)
Great UpgradesReview by Jen A

I started out with the original Mariposa and recently upgraded to this latest version. It keeps all the wonderful features that attracted me to the Mariposa in the first place (long side pocket and general comfort), but adds some great new improvements. First and foremost is the extra padding on the shoulder straps, which adds to the overall comfort of the pack. The straps also are narrower. All in all, the Mariposa is a great pack for people looking for a versatile and sturdy option. I love it! (Posted on 11/4/14)

I have been very pleased with this model backpack. I started out with the original Mariposa Plus back in 2010, and upgraded in 2012 to that years version. The color and features have changed since then but from what I see its for the best. I've been on week long adventures with this pack and really pushed its limits. It has been with me on the top of Whitney, bushwhacking my way through the Sisquoc river and it even held my snowshoes while hiking in the winter. The pack has defiantly proved it self worthy. My load, depending on the trip, is about 25 to 30 pounds but I'm pretty sure I've maxed it out a couple of times. Still going strong! The new features since I bought my last Mariposa are very cool. The ice pick and trekking pole holders are a useful addition. I would recommend anybody that wants a comfortable light weight backpack to look no further! Gossamer Gear is quality, enough said! Thank you for providing me with a great backpack that holds up to my abuse. (Posted on 10/20/14)
Love My First MariposaReview by Thistle

I received this pack recently for my birthday. (Of course I did the hard work of researching it and picking it out!) I absolutely love it! It is only the 2nd pack I've owned, but I don't think I'll need any other pack for quite a while. I love the large main compartment. I managed to get my 20 degree top quilt, my 0 degree bottom quilt,clothes and food for a couple of days, hygiene items, and quite a few misc. items and had room for quite a bit more if needed. My hammock fit nicely in the large side pocket, along with my stakes. The 2 pockets on the other side-The bottom pocket: My 1 liter Smartwater bottle and my Platypus gravity works filter system. (Waterbottle easily reachable without removing the pack! The top pocket held: my cook kit and fuel bottle. The very roomy back pocket held all the rest! From my tarp to my repair kit, first aid kit, pack cover, rain coat, seat pad (homemade), flip flops, rain pants and various other items! The pockets on the belt are roomy and held snacks, a camera, insect repellant, my buck knife, lip balm, and a small tin of altoids! I am a" wanna be light" backpacker, not an ultra light one. I have been working on lightening my load, and getting this pack saved me about 3 pounds. I am aware of some other gear upgrades that I am willing to make that will ultimately save me about 5 more pounds. My perfect pack will weigh between 19-23 pounds with food and water included. right now I'm at about 26. Thanks to the Mariposa, I am well on the way to my goal! Even at 26lbs, I get a pretty comfy carry! Can't wait to see what it's like at a lower weight. (Posted on 10/4/14)
