Choosing the right ultralight backpack is a critical decision for any thru-hiker or weekend adventurer. Two brands consistently top the list: Zpacks and Gossamer Gear. Both are renowned for their innovative designs, featherlight materials, and loyal followings. But which one is right for you? This Zpacks vs Gossamer Gear showdown breaks down the key differences in weight, durability, comfort, and price to help you make an informed choice.
In this comparison, we'll look at popular models from each brand, examine their construction and features, and consider the trade-offs. Whether you're a gram-counting purist or a hiker who values comfort above all, this guide will point you in the right direction.
Brand Philosophy and Design Approach
Zpacks is known for its use of Dyneema Composite Fabric (DCF), an incredibly lightweight and waterproof material. Their packs are minimalist, often frameless or with a simple carbon fiber frame, designed for hikers who want to shed every possible ounce. The Zpacks Sub-Nero Ultra 30L Backpack is a prime example, offering a streamlined design that appeals to fast-and-light enthusiasts.
Gossamer Gear, on the other hand, focuses on a balance between weight and comfort. They use Robic nylon, which is more durable and abrasion-resistant than DCF, and they often incorporate more padding and suspension systems. Their packs, like the popular Mariposa, are designed for hikers who want to carry a bit more weight without sacrificing too much on the scale.
- Zpacks: DCF construction, ultralight focus, frameless options.
- Gossamer Gear: Robic nylon, durability focus, more suspension features.
Weight and Materials
When it comes to raw weight, Zpacks generally takes the crown. The Sub-Nero Ultra 30L weighs in at around 14 ounces (400 grams), making it one of the lightest packs on the market. The use of DCF means it's also fully waterproof without a pack cover, saving additional weight and hassle. However, DCF is less abrasion-resistant than nylon, so you'll need to be mindful of sharp rocks and rough brush.
Gossamer Gear packs are slightly heavier but still ultralight. The Mariposa, for instance, weighs about 24 ounces (680 grams) in its standard configuration. The Robic nylon fabric is more durable and less prone to punctures, making it a better choice for off-trail adventures or hikers who tend to be rough on their gear. Additionally, Gossamer Gear packs often come with more padding and a more substantial hip belt, which can enhance comfort on longer carries.
- Zpacks Sub-Nero Ultra 30L: ~14 oz, DCF, waterproof.
- Gossamer Gear Mariposa: ~24 oz, Robic nylon, more durable.
Comfort and Fit
Comfort is subjective, but there are clear differences in how these brands approach it. Zpacks offers a simple, adjustable harness system that works well for many body types, but the lack of a rigid frame means the pack's load transfer depends on how well you pack it. For loads under 20 pounds, the Sub-Nero is supremely comfortable, but heavier loads can cause discomfort.
Gossamer Gear excels in this area. Their packs feature a more robust frame, often with a removable stay and a well-padded hip belt. The Mariposa can handle loads up to 30 pounds with ease, making it more versatile for hikers who occasionally carry more weight, such as when carrying extra water or food. If you prioritize comfort over the last few ounces, Gossamer Gear is likely the better choice.
- Zpacks: Best for sub-20 lb loads, minimalist harness.
- Gossamer Gear: Handles up to 30 lb, padded hip belt, more suspension.
Durability and Longevity
Durability is a major factor when investing in a backpack. Zpacks DCF is incredibly strong for its weight, but it can delaminate over time and is susceptible to abrasion. Many hikers report that Zpacks packs last for a thru-hike but may show signs of wear after extended use. The Sub-Nero Ultra 30L is no exception, so you'll want to handle it with care.
Gossamer Gear's Robic nylon is more abrasion-resistant and less likely to suffer from punctures. It's also easier to repair in the field with simple tape or a sewing kit. For hikers who plan to use their pack for multiple seasons or who frequently hike in rocky terrain, the increased durability of Gossamer Gear can be a significant advantage.
- Zpacks: Lightweight but less abrasion-resistant.
- Gossamer Gear: More durable, easier to repair.
Price and Value
Price is often a deciding factor. Zpacks packs are premium-priced, reflecting the high cost of DCF materials. The Sub-Nero Ultra 30L retails for around $300, which is a significant investment. However, for ultralight enthusiasts, the weight savings are worth it.
Gossamer Gear offers more budget-friendly options, with the Mariposa priced around $250. While still not cheap, it provides a better cost-per-ounce of durability and comfort. Additionally, Gossamer Gear frequently has sales and discounts, making their packs even more accessible.
- Zpacks: ~$300 for Sub-Nero Ultra 30L.
- Gossamer Gear: ~$250 for Mariposa, more frequent discounts.
Which Backpack Should You Choose?
The decision ultimately comes down to your priorities. If you're a gram-counting purist who wants the absolute lightest pack and are willing to handle it with care, the Zpacks Sub-Nero Ultra 30L is an excellent choice. It's also a great option for hikers who prefer a frameless, simple design.
If you value durability and comfort over the last few ounces, or if you often carry loads above 20 pounds, a Gossamer Gear pack like the Mariposa is the better investment. Its robust construction and superior load-bearing capabilities make it a versatile companion for a wide range of adventures.
Both Zpacks and Gossamer Gear produce outstanding ultralight backpacks, but they cater to different types of hikers. Consider your typical pack weight, the terrain you'll tackle, and your budget.
