Sibley Apex 520 Panorama | 17'1" Heavy-Duty Canvas Glamping Tent

About The Sibley Apex 520 Panorama

17'1" Diameter · 228.2 SQ FT · Up to 9 Guests · Four-Season Design

The Sibley Apex 520 Panorama is a spacious, professional-grade canvas glamping tent designed for long-term setups, backyard retreats, hospitality, rentals, events, and four-season outdoor living.

With approximately 228.2 square feet of interior space and room for up to nine people, the Apex 520 offers significantly more living space than a traditional bell tent. Its extended sidewalls create a bright, airy interior with room for real furniture, lounge areas, beds, and other amenities.

Constructed from heavy-duty Tentex® TC30 technical polycotton, the Apex features a specialized weather-resistant coating designed to protect against UV exposure, fading, moisture, mold, and rot while maintaining the natural breathability of canvas.

The Apex 520 Panorama features taller sidewalls, an oversized entrance, and five panoramic windows that bring natural light into the interior while creating a stronger connection to the surrounding landscape.

Its 360° retractable canvas sidewalls allow the tent to transition from a fully enclosed shelter into an open-air pavilion or lounge space while providing natural airflow and temperature regulation.

The removable, zip-in bathtub-style groundsheet is manufactured from heavy-duty waterproof rip-stop PVC to help keep the interior protected from water, mud, and pests.

Designed for convenient everyday and professional use, the Apex 520 includes heavy-duty hardware, reinforced stress points, screened windows and doors, electrical cable access, integrated storage organizers, reflective guy lines, forged steel stakes, and a spring-loaded center pole and door-frame system.

Setup can be completed by one person in approximately 10–15 minutes.
