The Sibley Apex Series features a German-made, oil-based coating that makes it UV-resistant, fade-resistant, water-repellent, and resistant to mould and rot — all while preserving the fabric’s breathability. This invisible treatment is, without question, one of the most critical factors in your tent’s performance, giving the Sibley Apex the edge as arguably the most durable tent in its class worldwide. The protective coating is integrated into the fabric fibers before the tent is even produced, ensuring long-lasting protection from day one.

Designed for intensive and professional use - Probably the most durable canvas tent in its class, worldwide.

360° Retractable Sidewalls - All-in-One Functionality - This tent is designed to adapt effortlessly to your needs. By day, roll up the 360° sidewalls and transform your tent into a breezy pavilion, shade structure, lounge area, or play space. By night, drop the walls and enjoy a fully enclosed, weatherproof camping tent. 

Superior Ventilation & Temperature Regulation - The 360° retractable sidewalls allow fresh air to circulate freely beneath the canopy, creating a natural cooling effect even during peak summer heat. Combined with the cotton canvas, this design reduces condensation, regulates temperature naturally, and keeps the interior comfortable in any season.

360° Mesh Wall for Bug-Free Comfort - Even with the walls rolled up, you stay protected. A full 360° mesh wall system ensures complete insect protection while maintaining airflow-so you can enjoy the breeze without worrying about mosquitos or other pests.

Cotton Canvas - Crafted from 95% natural cotton canvas, this tent offers unmatched comfort and breathability. Designed for four-season use, it keeps you cool in summer and insulated in winter while maintaining that classic canvas tent feel.

Zipped-In Tub Groundsheet - The industrial-strength groundsheet is made from 100% waterproof rip-stop PE. Its tub-shaped design prevents water, mud, and pests from entering-keeping your living space clean and dry on any terrain. Fully zippable, the groundsheet makes setup, cleaning, and packing effortless. Want to feel the grass or sand beneath your feet? Simply unzip and leave it out for a more natural camping experience.

Premium Weatherproof Coating - The Sibley Apex Series is finished with a specialized oil-based treatment that delivers UV resistance, fade resistance, water repellency, and protection against mould and rot-without ever compromising the canvas’s natural breathability. This invisible finish is one of the most crucial factors in long-term performance, giving the Sibley Bell Apex Series a clear edge as probably the most durable canvas tent in its class, worldwide.

100% Waterproof - Tested against extreme weather, the Sibley Apex remains completely dry inside-even during heavy downpours or tropical storm conditions. Wherever you pitch it-jungles, mountains, or coastal environments-you can trust it to keep the weather out.

Durable Mesh Windows & Door(s) - Intensive-use-mesh screens on windows and doors block insects while allowing airflow. Quick-release straps make it easy to roll up and secure doors or walls when you want an open-air setup.

Central Pole & A-Frame - Constructed from nickel-plated steel, the spring-loaded central pole and A-frame door support make setup fast and secure. The central pole includes an eyelet at the top for hanging lanterns or accessories, while the optimized A-frame design maximizes interior space and ensures easy entry.

Reflective ropes & Aluminium Carabiners and Sliders - UV-treated reflective guy ropes (5 mm polyester) with inner strength core and outer protective sheath for maximum durability. Fitted with aluminium tensioners and aluminium carabiners for fast, secure adjustments.

Forged steel tent pegs - Tough enough for hard and rocky ground.

Heavy-duty SBS zippers (ISO 17025 certified) for long-lasting reliability.

Quick & Easy Assembly - The Sibley Apex can be pitched by a single person in just 10 to 15 minutes thanks to its clever design and spring-loaded frame.

Electricity Access - Built-in cable access points (two cutouts on either side of the front door + a designated entry port) make it simple to run power into your tent for lighting, charging, or heating.

Safety & Standards - Certified fire-resistant canvas (BS7837:1996).

Portable & Organized - Each tent comes with separate storage bags for the canvas, groundsheet, and stakes, keeping transport organized and hassle-free.

Built-In Organizers - The tent comes with integrated storage pockets and organizers, perfect for keeping your essentials—like phones, lanterns, books—neatly tucked away and easily accessible.

Wood-Burning Stove: 

• Yes – all of our tents can be equipped with a stove.
  Unlike some models, this series does not come with a pre-installed stove vent, giving you the freedom to choose the stove type and placement that best suits your needs. Our CanvasCamp Stove Exits are compatible with any stove and can be installed anywhere in the tent in just about 10 minutes.

Note: We do not recommend using a wood-burning stove in a Sibley 300. The tent’s compact size makes it difficult to use a stove safely and comfortably.
