Outdoor Vitals Stormloft 40 Review: A Gold-Infused Quilt Revolution

For transparency I was sent this gear prior to release to test. As I live in hot and humid Texas a 40 degree quilt is the lowest we typically require. I am under no review requirements, these are just my opinions and thoughts.

I've got my hands on the brand new 2024 release of the Outdoor Vitals Stormloft 40 quilt, and I must say, the gold-infused down technology has caught my attention. It's not every day you hear about nano-particles being used in backpacking gear, let alone a precious metal. But does this innovative approach to moisture management really make a difference in the field?

I've been putting this quilt through its paces in various humid Texan conditions, and I'm here to share my findings. If you're curious about how gold can improve your camping experience and whether it's worth the investment, you'll want to stick around for what I've discovered.

ExpeDRY Down Technology: How It Works

At the heart of this revolutionary gear lies a technology that sounds more at home in a sci-fi novel than on the trail: gold-infused down. The star of the show is the pioneering ExpeDRY Down technology, developed by Allied Feather. This innovative insulation uses FUZE Technology to permanently bond gold nanoparticles to each down cluster.

Here's where the magic happens: these nanoparticles create an electrostatic shield that weakens water molecules' hydrogen bonds. The result? A quilt that dries a whopping 50% faster than those treated with traditional DWR. Unlike chemical treatments that can wear off over time, this nanoparticle infusion is permanent and chemical-free.

For us thru-hikers, this means saying goodbye to damp, clammy sleeping bags and hello to consistent warmth and comfort, even in challenging weather conditions. The ExpeDRY Down technology maintains its insulating properties even when faced with humidity or unexpected rain, preventing moisture from condensing into droplets.

Design and Comfort Features

The Outdoor Vitals Stormloft quilt series boasts several thoughtful updates:

• Extended corners that wrap around you better
• An easy-grip tab on the button for improved neck snapping
• New horizontal baffle arrangement for optimal down distribution
• Drawcord retention loops to prevent cord dangling
• A differential cut to prevent down compression
• Tapered shape for enhanced warmth and comfort
• More earthy color options, including a sleek black for the 40-degree version

These small details make a big difference when you're out in the wilderness, ensuring you stay cozy throughout the night.

Performance in Challenging Conditions

To truly understand the Outdoor Vitals Stormloft 40's capabilities, I put it through its paces in simulated rain and high-humidity conditions typical to my area. Here's a snapshot of my testing conditions:

The results were perfect for typical Texan needs and probably for those who dont have extreme cold or summer use other areas. In my head-to-head comparisons, the Stormloft 40 outperformed my Zpacks Summer quilt, drying faster and maintaining loft better.

Even after exposure to heavy humidity day and night, it bounced back to its original loft within hours. This rapid drying and loft retention isn't just about comfort—it's a crucial safety feature for multi-day treks in unpredictable weather.

Sustainability and Durability

For the environmentally conscious hiker, there's good news. The Stormloft 40 uses PFAS-free fabrics and DWR treatments, aligning performance with sustainability. The focus on durability and repairability also means less waste in the long run.

The longevity of the ExpeDRY Down treatment is particularly impressive. Being both permanent and chemical-free, you don't have to worry about its effectiveness diminishing over time or with washing. This durability is a crucial factor for thru-hikers and frequent backpackers who put their gear through rigorous use.

Comparison with Competitors

While specific competitor comparisons can be challenging, the Stormloft 40 is described as consistently outperforming other 40-degree quilts in high humidity conditions. It maintains loft and insulation better than traditional down quilts, especially in challenging weather conditions.
