Made of 100% cotton canvas.
CanvasCamp is the only bell tent manufacturer to proudly bear the Seal of Cotton™.
The 400 is ideal for 2 glampers on a full mattress or as many as 4 campers on sleeping pads.
Following the popularity of the Sibley Ultimate Series cotton canvas bell tents, we received requests from customers seeking all the same luxurious features but in a heavy-duty package for more demanding applications such as multiday festival camping, glamping, tent rentals, basecamps, bushcraft shelter, survival, long term use, and extreme weather conditions in all 4 seasons.
In response to those requests, CanvasCamp returned to the drawing board and developed the ProTech Series. The floor is thicker. The canvas is more durable. The poles are stronger. Even the screen material, guy ropes, and stakes are beefier. To top it off we’ve added a zip in/out mesh sidewall and sewn in screen door for maximum ventilation and bug protection. These exclusive features and improved materials have made the CanvasCamp ProTech series the highest quality and most popular Sibley (Bell) tent to date.
Mesh Walls: 360° ProTechtion
Traditional camp pests like bugs and critters are posing a greater threat campers with the increasing prevalence of vector borne illness like Zika, West Nile, and plague. Our ProTech series includes a mesh wall that zips on to the groundsheet and canopy, allowing you to roll up the canvas walls for maximum ventilation while keeping your tent sealed against pests. The mesh walls connect to the mesh door with extra sticky Velcro for a secure seal, offering a full 360° of mesh. When not in use the mesh wall can be rolled up and stowed neatly with the built in hook and loop system on the inside of the canopy, or they can zipped out removed completely. Mesh walls are also known as a double wall in the bell tent industry.
Roll Up Side Walls and Zipper Groundsheet: Pro Grade
Our ProTech groundsheets attach to the tent with a zipper and are made of are thick, thermally welded, rip-stop PVC (650 gr/m² or 19.17 oz/yd²). Completely water and vapor impenetrable, the ‘bathtub style’ floor rises 4 inches high to keep you dry even in standing water. Using a heavy duty size 10 zipper to attach the sidewall to the groundsheet, you can unzip the floor to roll up the canvas walls for maximum ventilation, or remove the groundsheet entirely for transport, storage, cleaning, or to enjoy the grass or sand beneath your feet. A tail gate style system of secure hooks and loops allows you to drop the bathtub wall near the door and peg it flat to prevent tripping and facilitate easy cleaning. A small gap between the two zippers in the back allows an electrical cord to enter the tent without compromising protection from rain and bugs.
Pro Integrated Mesh Door
The Sibley 400 ProTech includes a sewn in no-see-um mesh door in addition to the traditional canvas door. The tent is equipped with loops on either side of the door to neatly tie back the mesh door when not in use.
Pro Guy Lines and Tensioners
First time set up is a breeze with the Pro’s guy lines which are pre-attached to the tent and threaded through our tensioners. The Pro grade guy lines have been upgraded with corded nylon rope to make adjusting the tension on the line easier. Pro guy lines have are 5mm thick and have an additional UV resistant treatment. Plastic tensioners prevent edges from cutting into the guy lines and prolong the life of your tent.
Pro Stakes and Pegs
Specially designed for high wind or hard and rocky ground, our Pro stakes are made from the same high quality nickel plated steel our poles are made from. CanvasCamp exclusive Pro guy line stakes are 24cm (9.5 inches) angled and serrated to hold up to pounding into frozen or rocky round. A T shaped hook is welded securely to the stop to prevent guy lines from slipping off even in high wind. Pro groundsheet pegs are 50% thicker than standard pegs. The pegs for the floor are round to slip through the grommets on the groundsheet, and have a hook shaped top and hold the floor in place.
Pro Spring Loaded Poles
The poles on the Pro series have been beefed up from the standard poles included with the Standard, Deluxe, and Ultimate Series. Pro door poles are 23mm (.91 inch) and the center pole is 32mm (1.25 inches) in diameter. Internal spring loaded wires guide the pole sections together for quick and easy assembly. The center pole has a welded lanyard ring which can be used to hang an inner tent or chandelier.
Pro Canvas (360 gr/m² or 10.62 oz/yd²) is the best canvas for premium bell tents; but it’s not all about the weight. Our proprietary Pro treatment adds additional waterproofing to the natural water resistance of canvas, along with mold and UV resistance. Pro canvas is designed for long term use and wide range climates. A balance of breathability, waterproofing, and durability; Pro canvas is ideal for camping comfortably in all 4 seasons. Repairable and retreatable, a properly maintained Pro can last for years. Double stitched, flat-felled roof and side wall seams, seam gussets, and double-layer construction at all stress points create a bell tent that is as durable as it is beautiful.
100% Cotton canvas provides a natural waterproofing and breathability. Cotton fibers swell when damp, the tight weave prevents rain from penetrating and the surface tension of moisture drops on the outside combined with the steep angle of the canopy allows water to bead and run off. Moisture held in the air on the inside is still able to escape directly through the fabric, keeping internal humidity low and mitigating condensation.

100% Cotton Canvas
Our Sibley canvas is made exclusively from 100% cotton. Cotton is made from the seed hair of this hardy and drought tolerant plant. Sustainable, renewable, and one of the most biodegradable fabrics on earth. Our canvas is a soft, natural, earthy beige that glows inside and out with natural or artificial light. CanvasCamp is the only tent manufacture to carry the official Seal of Cotton®.
Windows and Vents
Every Sibley comes complete with windows and vents covered in no-seeum mesh to keep the bugs out while providing ventilation and airflow. Our half moon windows have zip up covers to allow you to customize your desired level of ventilation and privacy. Each window is equipped with loop fasteners to neatly hold the covers when the windows are unzipped. There are 4 windows and 3 vents on the Sibley 400.
All CanvasCamp tents are easily adaptable for use with a wood burning tent stove. Proper stove placement is dependent on stove size, tent size, flu exit style, desired temperature, and the environment you intend to camp in. One size fits all, pre-installed stove jacks fail to provide customers with the level of customization necessary to achieve ideal stove placement and maximum utility. To ensure proper placement and ideal efficiency, CanvasCamp offers modular stove jacks (sold separately) that can be easily installed in any cotton canvas bell tent in just a few minutes. Stove jacks are available in a variety of shapes and sizes so you can choose the jack that fits your tent and stove perfectly.
