What Is Ripstop Canvas?
Ripstop canvas is a fabric with a reinforced grid woven into it to help prevent small tears from spreading. Originally developed for demanding applications, it is now widely used across South Africa for safari tents, awnings, bakkie covers, outdoor blinds, and industrial covers.

Long before ripstop canvas was used for safari tents, bakkie covers, awnings, and outdoor blinds, it started with a simple problem.
Fabric tears.
A small cut becomes a bigger one. A puncture turns into a split. Wind, tension, movement, and time all work against the material until a minor issue becomes a costly replacement.
For engineers developing military and aviation equipment during the twentieth century, this wasn’t just inconvenient – it was something that needed solving.
The question was simple: How do you stop a small tear from becoming a big one?
The answer became known as ripstop.
Today, the same idea is found in some of the toughest working fabrics in South Africa – from safari lodges in Limpopo to workshops in Midrand and farms in the Karoo.
What is ripstop canvas?
Ripstop canvas is a polyester fabric woven with a reinforced grid of heavier yarns at regular intervals. This grid stops small tears from spreading – giving the fabric exceptional tear resistance without excessive weight. It is coated with acrylic for UV resistance and water repellency, making it one of the most practical outdoor fabrics available in South Africa.
A Simple Solution
Rather than making fabric thicker and heavier, manufacturers developed a woven structure that included reinforcement yarns at regular intervals.
Those yarns created the distinctive grid pattern that ripstop is known for today.
If the fabric was damaged, the reinforced sections helped limit how far the tear could travel.
It was a simple idea. Not a miracle material. Not an indestructible fabric. Just a smarter way of building fabric.
And like many good ideas, it found uses far beyond the problem it was originally designed to solve.
From Parachutes to the African Outdoors
Over time, ripstop moved into camping equipment, outdoor gear, marine applications, industrial covers, and eventually the coated outdoor fabrics used throughout Southern Africa today.
Because the problem hadn’t changed. Outdoor fabrics still get exposed to sun, rain, wind, abrasion, and everyday wear and tear.
Whether it’s a safari tent in Limpopo, a bakkie cover in Gauteng, or an awning on the Garden Route, outdoor materials work hard for a living. The fabrics that survive are usually the ones designed with that reality in mind.
A simple military engineering idea is now found in safari lodges in Limpopo, workshops in Midrand, and farms across the Karoo.
Why Ripstop Found a Home in South Africa
South Africans ask a lot from outdoor fabrics.
One day it’s 35°C and cloudless. The next day it’s a summer thunderstorm. In some areas, dust and wind are constant. In others, humidity and salt air become part of everyday life.
Outdoor products need to handle all of it. That is one reason ripstop became such a popular choice across the country. Its reinforced weave, combined with modern coatings and treatments, makes it well suited to applications that spend most of their lives outdoors.
Quick Guide: Which ripSMART Weight Is Right?
| Weight | Best for |
|---|---|
| 300gsm | Lightweight covers, bags, and general outdoor projects |

| 500gsm | Safari tents, heavy-duty covers, and high-wear applications |
Ripstop Canvas: Key Technical Properties
| Property | ripSMART Specification | Why It Matters |
|---|---|---|
| Base material | High-tenacity polyester | Stronger and lighter than cotton; does not absorb water or rot |
| Weave structure | Plain weave with reinforced grid every 5-8mm | The grid arrests tear propagation – a puncture stays a puncture |
| Surface coating | Acrylic both sides | UV stabilisation, water repellency, and anti-fungal protection |
| Available weights | 300gsm, 400gsm, 500gsm | 300gsm for lightweight covers; 500gsm for safari tents and high-wear applications |
| Colour fastness | Grade 4 (ISO 105-B02) | Colours hold under direct South African sun exposure |
| Water column | More than 1,000mm (ISO 811), all three weights | Resists rain penetration under normal outdoor conditions |
| Standard widths | 1.8m (ripSMART Classic, 300, 400 and 500gsm). Wider Select range on request | Wider rolls reduce seam frequency on large covers and tents |
Where You’ll Find Ripstop Today
Once you know what ripstop is, you start noticing it everywhere – from glamping lodges to garage workshops to the back of a bakkie.
Built to withstand years of outdoor exposure in some of Africa’s toughest environments.
Providing shade and protection for homes, lodges, restaurants, and entertainment areas.
Protecting tools, equipment, and cargo on South African roads.
Shielding machinery, equipment, and materials from the elements on farms and at work sites.
From rooftop tent covers to expedition gear and equipment bags built for hard use.
Why the Idea Still Works
The interesting thing about ripstop is that the original problem never disappeared.
Outdoor fabrics still get damaged. Ripstop simply approaches the problem differently. Instead of hoping damage never happens, it helps prevent minor damage from becoming major damage.
Decades after it was first developed, that idea remains just as relevant as ever.

Ripstop canvas FAQ
Why is it called ripstop? Does it actually stop rips?
Yes – that is exactly what it does. Ripstop fabric is woven with reinforcing yarns at regular intervals, creating a visible grid pattern. If the fabric is cut or punctured, those reinforced sections stop the damage from travelling further. It does not make the fabric indestructible, but it does prevent a small tear from becoming a large one.
Is ripstop canvas waterproof?
Ripstop canvas is naturally water-resistant due to its tight weave and acrylic coating. Smart Ikhaya’s ripSMART range can also be supplied with a WR (Water Repellent) treatment on request, making it suitable for applications that need enhanced water resistance. For fully waterproof applications, PVC-coated fabric is the more appropriate choice.
Which ripstop weight is right for my project?
300gsm is suited to lightweight covers, bags, and general outdoor projects. 400gsm handles awnings, lapa blinds, trailer covers, and bakkie covers. 500gsm is the right choice for safari tents, heavy-duty covers, and high-wear applications. If you are unsure, contact Smart Ikhaya and we will advise based on your specific project.
Can ripstop canvas be sewn on a standard machine?
Lighter ripstop (300gsm) can be sewn on a heavy-duty domestic machine. For 400gsm and 500gsm weights, an industrial sewing machine with the correct needle and thread is recommended. Many manufacturers and upholsterers across South Africa work with ripstop daily using standard industrial equipment.
