The Sibley 450 Ultimate is the best canvas tent for campers that just can’t decide and don’t want to compromise. The 450 is the goldilocks bell tent size, measuring 4.5 meters (14ft 9in) in diameter with 15,8 m² (171 ft²) of floor space. Not too big, not too small and easy to pitch with just one person. Easily fits queen bed and a whole suite of furniture for 2 people glamping. The Special Edition (SE) Ultimate tents have integrated mesh doors in addition to a range of features for camping in comfort in 3 seasons. Breathable and waterproof Classic Canvas (320 gr/m² or 9.5 oz/yd²) and a zip in/out bathtub style groundsheet keep you dry in rain and humidity.  Named "Best Glamping Tent" by Gear Patrol!

Made of 100% cotton canvas.
CanvasCamp is the only bell tent manufacturer to proudly bear the Seal of Cotton™.

The 450 is ideal for 3 glampers on a queen mattress and a cot, or as many as 6 campers on sleeping pads. A queen bed fits nicely in ¼ of the tent, giving you ample room for guests, gear, dogs, tables, chairs, and lounging. 

Canvascamp took the classic bell tent design and packed it with features focusing on ease of use, comfort, style, and versatility.  The Ultimate checks all the boxes for family camping, luxury camps, casual glamping, festivals, garden parties, car camping, back yard lounging, and 3 season use.

The water and vapor impermeable groundsheet attaches to the tent with a burly size 10 zipper that runs a full 360 degrees around the perimeter.  Giving you the ability to roll up the canvas side walls and let the breeze in, or remove the floor completely for transport, cleaning, storage, or to feel the grass between your toes!

Special Edition Integrated Mesh Door

The Sibley 450 Ultimate SE 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. 

Roll Up Side Walls and Zipper Groundsheet

Our Ultimate groundsheets attach to the tent with a zipper and are made of durable, thermally welded, PVC (540 gr/m² or 15.93 oz/yd²).  Completely water and vapor impenetrable, the ‘bathtub style’ floor rises 10cm (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.

Special Edition: PRO Spring Loaded Poles

The poles on the Ultimate SE series have been beefed up from the standard poles included with the Standard, Deluxe, and Ultimate Series.  The Ultimate SE comes with PRO grade poles: 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.   

A-frame Door

The 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. Each side of the door is equipped with loops and ropes to neatly tie back the doors to hold them open when not in use.

Every Sibley is compatible with a Sibley Connector, a bow-tie shaped attachment that can be used as an awning.

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 4 vents on the Sibley 450.

Durable Guy Lines and Tensioners

Our Ultimate series comes with 3mm guy ropes that will need to be tied on before your first pitch.  Check out our assembly instructions at the top of this page to get a feel for the initial set up process.  Our PRO Series comes with pre-attached guy lines and tensioners for those customers looking for an out-of-the-box set up.    Plastic tensioners prevent edges from cutting into the guy lines and prolong the life of your tent.

Standard Stakes and Pegs

The Standard stakes and pegs are designed for easy insertion and removal from average earth, like grass or forest floor.  The stakes for the guy lines are curved like a shovel to securely hold tension in the ground, and have a lip at the top to prevent the guy line from slipping off. 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.  All standard stakes and pegs measure 22cm (8.6 inches).  If your application requires the heavy duty stakes for high wind or hard, rocky, or frozen ground, check out our Pro Series.

Classic Canvas:

Our Classic Canvas (320 gr/m² or 9.5 oz/yd²) on the Ultimate, Deluxe, and Standard series is the perfect balance of performance and breathability.  Our proprietary treatment enhances the natural water resistance of canvas, and is excellent protection for moderate climates and casual use.  Repairable and retreatable, a properly maintained Classic Canvas tent 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 classic and durable bell tent.  For variable climates, four season, or long term use check out our PRO canvas on the PRO and ProTech Series.

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. 

Check out our FAQ for more information than you could ever need to know about cotton canvas and proper tent maintenance. 

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®.

Stove Compatibility

All CanvasCamp tents are easily adaptable for use with a wood burning tent stove.  Proper stove placement is dependent on stove size, tent size, flue 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.
