Gossamer Gear Mariposa Backpack Review

I've asked Santa Claus to search for the best backpack for my 5-year trip to Africa. Naturally, I told Santa to start the search by looking at the latest offerings of Gossamer Gear, which sponsored my last two thru-hikes, the Pacific Crest Trail and the Continental Divide Trail.

For my thru-hikes, I favored a minimalist backpack. When I backpack in the wilderness, I prefer a pack that weighs less than 226 grams (half a pound). Such ultralight backpacks have a small capacity and are uncomfortable when you carry more than 10 kg (22 pounds). That forces you not to take junk. For example, my CDT packweight was less than 3 kg (under 6 pounds).

However, in Africa, I won't be hiking nonstop. Instead, I'll mostly rely on vehicles to get around. Furthermore, I'll be able to buy food nearly every day. Translation: Low daily mileage + Frequent access to food = I can load up on luxury items :)

My ideal backpack for Africa

The requirements for my backpack are:

Less than 1 kg (2.2 pounds) when empty
High storage capacity (I won't use the capacity most of the time, but I want the option to carry extra stuff)
It should hold comfortably carry 15kg (33 pounds).
Several pouches/compartments to help organize stuff
Few zippers (they often break over time)

Mariposa Backpack Highlights

The Medium sized version weighs 765 grams (27 oz.)
The backpack is made out of custom 140 denier Dyneema GGridstop™ fabric.
7 exterior pockets
The OTT (over-the-top) closure system for a simple, solid, secure closure includes a zippered top pocket.
The "Shock Top™ shock cord top-of-the-pack lashing system for attaching your foam pad or other gear to the top of the pack
The Mariposa is best with loads under 30lbs but will handle up to 35 just fine

For capacity, it carries nearly 70 liters or 4,244 c.i. Let's break that down:

2860 c.i. (47 l.) in primary pack body/extension collar
1384 c.i. (22 l.) in all 7 pockets combined

Let's break down the 765 grams (27 oz.) backpack:

Pack Body = 15.85 oz (409 g) (Average for medium size)
Removable hip belt = 5.15 oz. (146 g.) (Average for medium size)
Aluminum curved stay = 3.5 oz. each (96 g.) (Average for medium size)
Sit-light Pad = 2.0 oz ( 51 g. ) (Average)
extra shock cord and cord locks .55 oz (16 g.)

Verdict

With just two months to start my Africa trip, this looks like the backpack I need. Of course, thru-hikers and backpackers will also appreciate this backpack, especially for winter trips or trips where you have to carry more than a week of food. Its durability gives me the confidence that it will last three years. Yes, it will be mangled, but it's tough.

The only downside is that there are two closure clips to lock it down. I miss the old Mariposa backpack, which just had one closure. Still, given the other improvements, it seems we've got ourselves a winner! I'd give it 4 out of 5 stars. Buy it!
