The single most common question we get asked before someone buys their first bell tent is not "what size do I need?" it is "what is the difference between cotton and polycotton?"
It is a genuinely important question because the canvas type affects everything: how warm the tent is in winter, how cool it stays in summer, how much it weighs, how quickly it dries, and how long it lasts. Getting this wrong is an expensive mistake.
Here is the honest answer: no brand bias, just the real differences between the two fabrics and which one suits which buyer.
What Is Cotton Canvas?
Cotton canvas is the original bell tent fabric and still the most popular choice for buyers who want a tent that performs in every season and lasts for a decade or more.
It is woven from natural cotton fibres usually at a weight of 285gsm to 360gsm for bell tents and treated with a waterproofing agent at the factory. The natural fibre structure of cotton makes it breathable, which means moisture and condensation can escape through the fabric rather than building up inside the tent.
Cotton canvas bell tents require weathering before their first use, the process of getting the tent wet so the cotton fibres swell and tighten, sealing the stitching holes and making the fabric fully waterproof. This sounds like a disadvantage but takes less than an hour and only needs to happen once.
Cotton canvas in summary:
-
Breathable : minimal condensation in summer and winter
-
Naturally insulating : warmer in cold weather, cooler in heat
-
Heavy : a 5m cotton tent weighs 35–39kg
-
Requires weathering, but with a Bell tent Sussex tent our proofing is so good just put it up the first time you use it.
-
Longer lifespan : 10–20 years with proper care
-
Higher price point
What Is Polycotton Canvas?
Polycotton is a blend of polyester and cotton fibres typically 65% polyester and 35% cotton, though this varies between manufacturers. The polyester content makes the fabric lighter, more resistant to water from the outset, and faster to dry when packed away wet.
Polycotton bell tents do not require weathering; they are water-resistant straight from the bag. They are also significantly lighter than equivalent cotton tents, which matters if you are transporting the tent regularly or carrying it any distance.
The trade-off is breathability. The polyester fibres are not breathable in the same way cotton is, which means polycotton tents can build up more condensation inside particularly on warm nights or when multiple people are sleeping in the tent.
Polycotton canvas in summary:
-
Dries faster when packed away damp
-
Less breathable than cotton , more condensation in summer
-
Lower price point , typically £100–£200 less than cotton equivalent
-
Shorter lifespan , typically 5–10 years

Which Should You Choose?
Choose 100% Cotton If:
You camp year-round or in shoulder seasons. The breathability and natural insulation of cotton canvas makes a significant difference in autumn and winter. With a stove inside, a cotton bell tent is genuinely warm on cold nights in a way polycotton cannot match.
You want the longest possible lifespan. A quality cotton bell tent, properly maintained, will still be in excellent condition in fifteen years. If you are buying for a glamping business or making a serious long-term investment, cotton is the only sensible choice.
You prioritise comfort over convenience. Cotton is heavier and requires weathering; neither is a dealbreaker, but both require a bit more effort than polycotton.
You are eco-conscious. Cotton is a natural, biodegradable fibre. Polycotton contains polyester, which is a synthetic plastic-derived material.
Choose Polycotton If:
You are on a tighter budget. Polycotton tents offer a genuine glamping-quality experience at a lower price point if your budget is the deciding factor, polycotton is a better choice than a cheap cotton tent.
You need rapid deployment and takedown. Event hirers and companies that pitch and take down tents regularly often prefer polycotton for the drying speed advantages.
What About Fireproof Canvas?
If you are using a bell tent commercially for a glamping site, at public events, or in any setting where the public will be staying, standard cotton or polycotton canvas will not satisfy your insurance requirements or local authority fire safety checks.
Commercial use requires BS7837-rated fireproof canvas, a treated cotton canvas that meets the UK fire safety standard for tented accommodation. Both our cotton and fireproof canvas tents use 100% cotton construction; the fireproof version has an additional fire-retardant treatment applied.

The Bottom Line
For most UK buyers who plan to use their bell tent more than a few times per year especially across multiple seasons 100% cotton is the better investment. The breathability, insulation, and longevity advantages outweigh the extra weight and the one time weathering process.
For festival goers, occasional campers, and anyone prioritising portability and budget, polycotton offers a genuine and practical alternative that delivers most of the bell tent experience at a lower cost and weight.
