Carbon Dome 2 — Ultralight Backpacking Tent

At just 22 oz, the Carbon Dome 2 is one of the lightest truly freestanding two-person ultralight tents available. Built from Dyneema® Composite Fabric (DCF) and supported by an ultralight carbon-fiber pole structure, it delivers the simplicity and stability of a freestanding tent at a weight normally associated with trekking-pole shelters.

Four large mesh vents promote airflow and help manage condensation, while the spacious two-person interior provides plenty of room for one and an exceptionally lightweight shelter for two. Each Carbon Dome 2 is built in small batches with an emphasis on minimal weight, simplicity, and performance.

Designed for three-season backpacking, the Carbon Dome 2 is equally at home on weekend trips and long-distance trails like the Pacific Crest Trail (PCT), Appalachian Trail (AT), and John Muir Trail (JMT).

Ultralight Materials

Dyneema® Composite Fabric

The Carbon Dome 2 is built from Dyneema® Composite Fabric (DCF), an exceptionally lightweight, waterproof composite developed around ultra-high-molecular-weight polyethylene (UHMWPE) fibers. DCF provides an outstanding strength-to-weight ratio while eliminating the water absorption and stretch associated with many traditional tent fabrics.

The result is a shelter that stays light, packs small, and maintains its shape when conditions turn wet.

Custom Carbon-Fiber Pole System

A custom ultralight carbon-fiber pole system gives the Carbon Dome 2 its fully freestanding structure without the weight penalty of conventional aluminum tent poles.

The narrow-diameter carbon poles were selected specifically for the Carbon Dome 2 to balance weight, flexibility, and structural support, allowing the complete shelter to weigh just 22 oz while retaining the convenience of a truly freestanding design.

Special Features


    Ultralight Dyneema® Construction

    Blue, White, and Olive Green Carbon Dome 2 tents are constructed with 0.51 oz/yd² Dyneema® Composite Fabric (DCF) for an exceptional strength-to-weight ratio. 

    Waterproof Zippered Door

    A large front entry provides easy access without adding the weight and footprint of a traditional vestibule. Dual waterproof zippers help protect the opening in bad weather, with reflective zipper pulls for easy visibility at night.

    Fast, Simple Setup

    The Carbon Dome 2's freestanding architecture makes setup remarkably simple. Slide the carbon-fiber poles through the integrated sleeves, tension the structure, and stake the ventilation flaps.

    Setup takes approximately two minutes, with minimal staking required under normal conditions. Additional anchoring is recommended when conditions warrant.

    Four-Point Ventilation

    Four strategically positioned mesh vents promote airflow throughout the shelter and help manage condensation. Adjustable vent flaps allow additional protection from weather, while reflective guylines improve nighttime visibility.

    Compact Freestanding Footprint

    With no mandatory vestibules or extensive guyline system, the Carbon Dome 2 requires a footprint of only approximately 7.5 × 4 feet.

    Its compact freestanding design makes it particularly useful when camping on small tent pads, rocky terrain, or established campsites where staking options and usable space are limited.

    Waterproof DCF Shelter

    Dyneema® Composite Fabric is inherently waterproof and doesn't absorb water or stretch when wet like many conventional woven tent fabrics.

    Critical seams are taped and remaining seams are sealed to create a highly weather-resistant shelter while maintaining an exceptionally low overall weight.

    DCF Bathtub Floor

    The bathtub floor is constructed from substantially heavier 1.0 oz/yd² Dyneema® Composite Fabric for increased durability in the highest-wear area of the shelter.

    Raised floor walls extend approximately 8 inches above ground level, helping protect the interior from runoff, splashback, and wet ground conditions.

    Freestanding Dome Structure

    The Carbon Dome 2's crossed-pole architecture creates a rigid, self-supporting structure designed to distribute wind loads across multiple sections of the shelter.

    Four aluminum stakes are included for anchoring the tent, while additional guy-out points can be used when greater stability is needed in exposed or windy conditions.

      Construction and Design

      Freestanding Dome Architecture

      The Carbon Dome 2 is built around a proven cross-pole dome architecture, providing a stable, self-supporting structure without relying on trekking poles or extensive guylines to maintain its shape.

      By combining this classic geometry with ultralight materials and a purpose-built carbon-fiber pole system, we've created an exceptionally lightweight truly freestanding shelter with the simplicity, usable interior space, and straightforward setup that make dome tents so effective.

      Large Front Entry

      A generously sized front door makes entering and exiting the Carbon Dome 2 easy while keeping the overall design simple and lightweight. The door opens from the top, allowing it to double as additional ventilation when conditions permit.

      When fully opened, the oversized entry provides enough room to stand with your feet inside the tent, making it considerably easier to change clothes, organize gear, or get in and out of the shelter.

      Waterproof zippers and reinforced, sealed construction around the entry help protect the interior when conditions turn wet.

      Bonded & Reinforced Construction

      Wherever practical, the Carbon Dome 2 uses adhesive-bonded construction rather than conventional stitching, reducing unnecessary needle holes while creating strong, lightweight seams ideally suited to Dyneema® Composite Fabric.

      Where sewing is required for structural components, critical areas are reinforced with additional DCF and/or DCF repair tape to distribute loads and protect the seam.

      This hybrid construction method allows us to use the technique best suited to each part of the shelter—bonding where it saves weight and improves weather protection, and reinforced stitching where additional mechanical strength is needed.

      Setup Instructions

        • Remove the tent from its bag.  Unroll and unfold the tent.  Be careful not to let the wind blow any parts away, like the small rain fly.  Lay the tent out flat, with the top of the tent facing up.
        • Remove the tent poles from the pole bag and assemble the poles, inserting the male end of each pole segment into the female end, as guided by the internal shock cord.
        • Slide the assembled tent poles through the gray colored sleeves so that they cross in the middle of the tent.  Each pole must pass through 4 sleeves.  Insert the ends of each pole into the grommets you'll find on each of the 4 corners.  If the material is too tight, loosen the webbing on the door end of the tent to allow the ends of the poles to reach the front grommets.
        • Once the tent has taken shape, carefully tighten the webbing straps on the door end of the tent until you achieve a nice taught pitch.
        • Use the provided tent stakes to stake down the small guy lines that extend from the the ventilation flaps.  It is important that the stakes are positioned at about a 30 or 45 degree angle to the ground, with the top of the stake pointing away from the tent.  The guy lines and flaps should form roughly a 45 degree angle with the ground.  Slide the small plastic tensioner up toward the tent until the pitch is nice and taught.
        • To attach the rain fly to the top of the tent, lay the rain fly over the tent.  Unfasten the cords at each corner of the fly, then loop them around the top pole sleeve on each corner, under the pole.  There is a small piece of DCF tape reinforcing the edge of the pole sleeve; this is where you wrap the cord around it.  Finally, loop the cord over the small plastic cord lock.  Once all 4 cords are looped around their respective cord locks, cinch the cords by pinching the cord lock buttons and pulling the cord to your desired tension.
        • When taking your tent down, do each of the above steps in reverse.  Once flat, fold the tent long-ways in thirds, then roll the poles, stakes and rain fly in with the tent.  Leave one of the door zippers open and start rolling the tent from the back end (non-door end) so that air can escape through the door as you roll it, before sliding the rolled tent into the tent bag.

        Care Instructions

        Zipper Maintenance

        Be sure to keep your zippers clean by keeping them out of the mud and dirt.  We suggest rolling the door inward and letting it sit on the inside of the tent so that dust doesn't collect in the zipper teeth.  We also recommend cleaning and lubricating the zipper with Zipper Cleaner/Lubricant whenever the zipper isn't as smooth.  Don't force the zippers or they could break.  If you're in the backcountry and need to maintenance your zippers, we recommend using warm soapy water, if it is available.  Also, don't tug on your zipper pulls and weird angles.  There are tabs at the bottom of each zipper, or simple pinch part of the material behind where you intend to pull from to reduce stress on the zippers. 

        Door Care

        As mentioned above, when opening the door to your tent, roll it down and sit it on the inside of the tent.  Whatever you do, don't lay it out in front of the tent.  And for the love of God, don't stand or kneel on the door flap if you do set it outside.  This could cause small punctures in the door flap, which would render it less waterproof.  If you get punctures, repair them with small patches of DCF Repair Tape. 

        Keep the Tent Clean

        When rolling up your tent on a backpacking trip, try to brush off as much dust as you can as you roll it.  Over time, grains of sand or small rocks can slowly wear on the material or cause small punctures.  If you get a puncture in the material, we recommend patching it with a small piece of DCF Repair Tape, which is included with each tent. 

        Don't Expose your Tent to Extreme Heat

        Adhesives are used throughout the construction process of the tent, including the seam sealing tape.  Although these adhesives hold well in cold conditions, they become less effective in extremely hot conditions.  Try not to leave your tent in a hot car for an extended period of time.
