Gear Review: Cinder Cone 4-Person Pyramid Tent By SlingFin

The SlingFin Cinder Cone 4P Pyramid Tent is built for mountain expeditions, group camping trips, and serious weather. With a roomy four-person capacity and modular setup options, it’s a versatile shelter for those who need reliable wind protection and spacious sleeping quarters. This review takes a closer look at how the Cinder Cone 4-Person performed during field testing in variable weather and how it stacks up against other pyramid-style shelters.

Standout Features:

• Modular Setup Options: The Cinder Cone 4P can be set up as a double-wall tent with the mesh body or stripped down to the pyramid fly for a more minimalist, ultralight setup.
• Exceptional Wind Resistance: The pyramid structure and tensioned guylines kept the tent stable in wind gusts up to 40 mph during our testing.
• Ample Headroom and Interior Space: With a 4-person capacity, there’s plenty of room for campers, gear, and even a small table for basecamp setups.
• Durable Construction: SlingFin uses top-tier materials, reinforced stitching, and a bombproof center pole to ensure the Cinder Cone 4P can withstand extended use in harsh conditions.
• Multi-Season Versatility: The mesh body option is ideal for warm-weather trips, while the full fabric setup can handle snow and cold.

My Experience with the Cinder Cone 4-Person Pyramid Tent

I tested the SlingFin Cinder Cone 4P during a multi-day trip through the San Juans, setting it up in high winds, rocky ground, and hail. The tent’s pyramid structure excelled in wind resistance, with its single center pole and guylines holding firm against gusts that would have collapsed lesser shelters.

Inside, there is enough headroom for me to stand up straight at 5'6", and the 4-person capacity made it comfortable for two people plus all our gear. This tent provides excellent ventilation during warmer nights, but the full fabric setup keep drafts to a minimum when temps dropped. While the Cinder Cone 4P isn’t the lightest shelter, it is quite lightweight and packs down super small.

This is a pretty massive tent when it comes to ground space, which isn't a huge deal for many adventures. But I will caution that finding the space to pitch the Cinder Cone in a dense forest, in a cactus-filled desert or wherever else space may be limited is complicated. And this tent might not be the best choice for those adventures. For those, I would recommend the Portal 3 by SlingFin.

Pros and Cons:

The SlingFin Cinder Cone 4P Pyramid Tent is a beast of a shelter, built for high-altitude basecamps, packraft trips, and unpredictable weather. It may not be the lightest option, but it is indeed very light. The wind resistance, modular design, and ample interior space make it a standout choice for those who need serious weather protection without sacrificing comfort.

Whether you’re setting up a basecamp for a mountaineering mission or just need a roomy, durable tent for a multi-day trek, the Cinder Cone 4P delivers on both stability and versatility. It’s not the easiest setup for beginners, but once dialed in, it’s a fortress against the elements.
