SlingFin Cinder Cone 4P Pyramid Tent

What We Think

For backcountry travelers who need a shelter that laughs at alpine wind and still packs down to the size of a water bottle, the SlingFin Cinder Cone 4P delivers a rare combination of storm-ready durability and ultralight portability.

This pyramid tent scored a 8.6 overall, earning that mark through genuinely impressive weather performance and a 9.8 from owners who have put it through real mountain conditions.

At 2 pounds 7 ounces with 81 square feet of floor space, it occupies a sweet spot that most 4-season shelters simply cannot reach.

Weather Resistance

The Cinder Cone scored a 9.0 in Weather Resistance, and the engineering behind that number is worth understanding.

The 10-denier sil/sil nylon fly paired with an ALUULA-reinforced top cap creates a structure that owners consistently describe as "bombproof" in high winds.

The 1800mm PE-coated floor provides serious wet-ground protection, well above the 1200mm threshold where we start worrying about groundwater seepage.

What really separates this shelter from typical pyramids is the multi-vent system: upper thru-vents combined with perimeter pull vents create a chimney effect that owners report dramatically reduces the condensation problems that plague single-wall designs.

Space & Comfort

The 81 square feet of floor area and 72-inch peak height earned a 9.0 in Space & Comfort, which is exceptional for a shelter this light.

Owners with gear-heavy setups consistently praise the ability to store packs, boots, and equipment inside while still sleeping two people comfortably.

The single-door design is a tradeoff worth noting: it works fine for solo use or couples, but becomes a coordination exercise when multiple people need midnight exits.

Quality & Durability

The Cinder Cone scored a 8.0 in Quality & Durability, reflecting both premium materials and one notable gap.

The carbon 3K twill pole, YKK Aquaguard zippers with spare sliders, and radial seam tape corner reinforcements all signal serious build quality.

However, the seams lack factory-applied seam tape, which means you will need to seal them yourself before heading into wet conditions.

This is the tent's clearest weakness: at $470, expecting buyers to DIY their seam sealing feels like a miss.

Ease of Use

The Dyneema Quick-Pitch cord system addresses the traditional pyramid tent frustration of fiddly guy-line tensioning, and owners confirm the 3-5 minute setup time is realistic even in challenging conditions.

One recurring complaint: the slippery sil/sil fabric makes stuffing the tent back into its sack more annoying than it should be.

This scored a 8.0 in Ease of Use.

Value for Money

At $470, the Cinder Cone sits in interesting territory, scoring a 8.0 in Value for Money.

The Hyperlite Mountain Gear UltaMid 2 costs $730 and shaves weight down to 1.2 pounds, but offers less floor space and lacks the Cinder Cone's integrated ventilation system.

If you want a more traditional freestanding 4-season design from SlingFin, the CrossBow 2 4-Season Tent runs $790 but weighs over twice as much at 5.1 pounds.

User Reviews

The 9.8 User Reviews score reflects owners who have genuinely tested this shelter in demanding environments and come away impressed.

The most common praise centers on wind stability in exposed alpine terrain.

Who It's For

This tent is built for the mountain backpacker or ski tourer who needs legitimate 4-season protection without the weight penalty of traditional expedition shelters.

If you are planning high routes, shoulder-season alpine trips, or winter camping where wind exposure is a real concern, the Cinder Cone belongs on your shortlist.

Car campers and fair-weather backpackers should look elsewhere.

The Bottom Line

The SlingFin Cinder Cone 4P earns its 8.6 score by solving the classic pyramid tent problems, delivering storm-worthy protection at a weight that does not punish your knees on the approach.

The unsealed seams require prep work before your first trip, which is a legitimate annoyance at this price.

For backcountry travelers who prioritize weight and weather resistance above all else, this is one of the most compelling 4-season pyramids available.
