Following the popularity of the  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.GroundsheetOur ProTech series groundsheets are thick, thermally welded, 19.2oz/yd² ripstop PVC.  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 eyes allows you to drop the bathtub wall near the door and peg it flat to prevent tripping and facilitate easy cleaning.Spring Loaded PolesOur durable nickel plated steel poles have internal spring loaded wires that 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.A-frame DoorThe Sibley’s signature A-frame door allows for easy entry and exit, and holds the canvas at 90 degrees from the ground preventing rain from falling into the tent when moving in and out.  Spring loaded poles snap together quickly for easy set up and fold together for fast take down and organized storage.  The floor is equipped with two stirrups which hold the foot poles of the A-frame securely in place.  The top of the A-frame door is equipped with a pin that sits in a grommet at the peak of the door ensuring proper placement.  A rain cap is then placed over the pin and grommet to keep rain from running down the poles.  The canvas door zips together vertically and along the bathtub floor. The ProTech is equipped with an integrated no-seeum mesh door sewn in to the tent for maximum ventilation and bug protection.  Each side of the door is equipped with loops and ropes to neatly tie back the canvas and/or mesh doors to hold them open when not in use. Every Sibley is compatible with a , a bow-tie shaped attachment that can be used as an awning.Windows and VentsEvery 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.Durable Guy Lines and TensionersFirst time set up is a breeze with 5mm corded nylon rope with UV resistant technology pre-attached to the tent and threaded through our tensioners.  Plastic tensioners prevent edges from cutting into the guy lines and prolong the life of your tent.Mesh WallsNew for 2016 by popular demand!  Traditional camp pests like bugs and critters are posing an increasing threat with the increasing prevalence of vector borne illness like Zika, West Nile, and plague.  Our ProTech series comes standard with 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.Steel Stakes and PegsSpecially designed for hard and rocky ground, our Pro stakes are made from the same high quality nickel plated steel our poles are made from.  Angled and serrated stakes are welded securely to a T hook offering the most secure guy line attachment to date.  Our groundsheet pegs are designed for easy insertion and removal from average earth.  For pegging a groundsheet to especially hard or rocky soil, D60 nails are cheap, easily sourced, and can be placed and removed with a standard claw hammer.PRO CanvasOur 10.6oz/yd² army duck canvas is our heaviest and most durable canvas; 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 heavy use and extreme climates.  Repairable and retreatable, a properly maintained PRO can last for years and 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. 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 on the outside combined with the angle of the canopy allows water to 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.  Check out our  for more information than you could ever need to know about Cotton Canvas. CottonOur canvas is exclusively 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®.Stove CompatibilityAll of our tents are easily adaptable to fit a modular stove jack for a tent stove.  Proper stove placement is dependent on stove size, desired temperature, and intended use; thus we provide you the advice and systems to place a stove in best location for you.  Simply cut a hole in your desired flu exit location and screw on the stove jack.  Read our  or  to learn more about the best stove placement for your desired application.  Not for use with open fire pits.  We encourage you to be vigilant about fire safety and are happy to answer any questions or concerns you may have.  CanvasCamp cannot be held liable for any damage or injury to persons or property resulting from the use or misuse of fire or flammable materials in or around our tents.
