Advantages of the Mariposa Backpack

The Mariposa has mostly positive reviews, with these two advantages being the most popular.

Plenty of Sizing Options for Tall or Short Backpackers

Just one look at the specs lists shows you the huge range of sizing choices you get. Unlike most backpacks, the Mariposa hip belt is sold separately. This allows for a more custom fit since some have issues with one size fits all or basic S/M/L choices.

The smallest backpack option would be for someone 4′ 11″ to 5′ 4″ with a 22″ to 28″ waist. This means even youth and teens would likely wear this backpack comfortably. Those who often have trouble due to unique body types, like being very short but stocky or very tall yet very thin can find something that will work for them.

The harness fits equally well on both men and women, with plenty of adjustment for individual body shape. This really is backpack men and women of all sizes and ages will enjoy carrying on long hikes.

Extremely Well Designed and Constructed

This backpack truly is unisex in design. Unfortunately, many brands that try to make unisex backpacks end up just creating a bag more comfortable for men.

While this does make sense since most outdoor enthusiasts are men, it leaves women with much to be desired in terms of comfort. Gossamer Gear kept these issues in mind and was able to devise sizing options to work with literally everyone.

Another awesome thing about Gossamer Gear as a brand is that they will go back and redesign popular bags to improve them even more. The Mariposa has been redesigned from its original form to incorporate a new belt with additional stability, a more unisex belt shape, and larger hip pockets. It also now has a removable stay which can come in handy for some.

At a 60 liter capacity and a 35lb maximum load weight, the Mariposa offers plenty of space for most weekend backpacking trips. If you are adept at backpacking you can likely get even more out of this bag by packing in an ultralight fashion.

This bag is versatile enough to be used for air, bus or car travel as well. It won’t take up too much space but still gives enough room for a few days worth of clothing, accessories, shoes, etc.

Disadvantages of the Mariposa Backpack

The Mariposa is easily a strong 4.5-star backpack with numerous positive reviews from customers of all kinds. Despite everything it has going for it, there are still some little complaints some have found. Here are two of the most commonly cited downsides.

Requires a Rain Cover in Wet Conditions

While the 100 denier Robic nylon on the majority of the backpack is somewhat water-resistant, don’t expect it to keep your gear dry in heavy rain. Most customers find that light rain isn’t an issue on the actual fabric but rather through the zipper of the bag. There is no water protection on or under this zipper which means rain can easily gather at the seams and enter.

Unfortunately, the Mariposa doesn’t come with an integrated rain cover so you will have to provide your own. Typically you can find an elastic one to fit this 60L backpack for under $20.

Slightly Overpriced Compared to Competition

Depending on the options you go with, the Mariposa backpack runs anywhere from $175.97 to $215.97.

While most agree the bag is worth the money and don’t feel it is a waste, it’s still worth noting that the Mariposa is more expensive than other competing bags. If you have a very strict budget this bag may not be worth it when you could save $50+ on a comparable backpack.

Similarly, if you are only a casual backpacker spending $200+ on the backpack you only use a handful of times every year may leave you feeling like you aren’t getting your money’s worth. All in all, this bag is worth every penny if you have had issues with other backpacks and are a frequent/serious backpacker that will use this model regularly.

Overall you’ll find the Mariposa backpack to be an excellent example of the quality that Gossamer Gear produces. The bag is the perfect size for most backpacking trips and general travel. It is incredibly comfortable and the sizing options ensure almost everyone can find a near-custom fit for their body.

Many brands struggle with creating truly durable, attractive, and spacious unisex backpacks yet Gossamer Gear seemed to hit every requirement with the Mariposa. If you’re in the market for a new bag, this one is definitely worth considering.
