Built Right, Not Overbuilt
Fabric choice isn’t decoration. It decides how your pad wears, feels, and lasts.
Every scrape, fold, drag, and drop hits the outer shell first — so getting the fabric wrong means the rest doesn’t matter.
At Slaphappy, we don’t pick materials because they sound tough. We pick them because they’ve proven themselves — both in the lab and on rock.
Why Fabric Matters
A pad’s outer shell takes more abuse than any other part of the build.
Dragging across gritstone, catching boot rubber, scraping on rock edges, and compressing under foam — all of it breaks fibres down over time.
The right fabric should:
-
Resist abrasion from rock, mud, and sand
-
Stay stable under load and friction
-
Handle UV, water, and temperature changes
-
Stay flexible in cold conditions
-
Protect the foam system without adding unnecessary weight
Two pads can look identical but age completely differently. The difference lies in what’s underneath the colour — fibre quality, coating, and construction.
The Outer Shell — 1000D Nylon
Our main outer shell uses 1000D nylon, supplied by a local supplier just 70 minutes from our workshop.
We chose to source this as locally as possible. While it’s not UK-made, it’s consistent, durable, and genuinely bomber — both in data and in the field. It’s exactly what we need — nothing more, nothing less.
Why we use it:
1000D nylon is a benchmark material in high-impact gear. It’s tough, stable, and proven across outdoor, military, and industrial applications.
We’ve compared data sheets from multiple suppliers against what’s commonly used in climbing pads, and the pattern is clear:
-
Competitors using lightweight polyester or ripstop nylon save grams but sacrifice durability. These lighter fabrics feel smoother and can look more technical — but their tear strength and abrasion resistance drop dramatically once they start to wear.
-
1000D nylon, on the other hand, keeps its integrity for sessions, weeks, and seasons.
What it actually does:
-
Abrasion resistance: Handles scraping and dragging without fraying or thinning prematurely.
-
Tear resistance: The dense weave stops rips from running — a small nick won’t become a full failure.
-
Weather tolerance: The PU-coated backing repels water and resists wicking, keeping internal foam systems drier even on damp ground.
-
Shape retention: Maintains structure over time, even under load and repeated folding.
-
Repairability: Can be restitched or patched easily, so a small tear doesn’t mean replacement.
We use it because it performs consistently, not because it’s fashionable. It gives the right kind of “overkill” — strength where it matters, without unnecessary bulk or weight.
The Landing Deck — 1000D Cordura® HP (Printed Fabric)
Our landing decks use 1000D Cordura® HP, a high-performance polyester printed here in the UK.
We tested printed fabrics from North America, Asia, and Europe. Many looked great on spec sheets but fell short in the real world — especially under tear testing and long-term durability.
Why we use it:
Cordura® has become the industry benchmark for high-wear textiles for good reason. Cordura® HP combines a printable surface with the durability and abrasion resistance the Cordura® name is known for.
What it actually does:
-
Abrasion resistance: The dense 1000D weave outlasts standard polyester or lightweight ripstop by a wide margin in both lab and field conditions.
-
Tear strength: Its balanced weave prevents small nicks from spreading as quickly as other printed materials — a major factor in pad lifespan.
-
Weather resistance: The PU backing and DWR top finish reduce moisture absorption and slow foam degradation.
Printed fabric considerations:
Printed surfaces are less abrasion-resistant than plain-dyed nylon — it’s part of the trade-off for colour and pattern. That’s why we reinforce top corners, which are one of the highest-wear points on any pad, and why we recommend not flipping pads upside-down during use.
All printed decks are UK-printed, allowing us to control quality and colour consistency while supporting domestic suppliers.
How We Test
We don’t take spec sheets at face value.
For many fabrics, we review the manufacturer’s performance data and validate it against our own requirements.
For fabrics without reliable data, or where results are inconsistent, we send samples to external test labs for independent verification.
Our testing includes:
-
Abrasion testing: Repeated drag and fold cycles to simulate field wear.
-
Tear resistance: Measuring how fast rips spread under tension.
-
UV and weather exposure: Monitoring fade and strength loss over time.
-
Field validation: Actual outdoor use on our end— tested with climbers on real rock — not just bench tests.
If a fabric lasts through hundreds of sessions without delaminating, tearing, or softening, it earns its place in production.
Bottom Line
Fabric is the first layer of protection, not an afterthought.
We don’t use 1000D nylon and Cordura® HP for marketing points — we use them because they last longer, perform better, and protect your pad where it matters most.
Strong enough to last, light enough to carry, and built to be repaired — not replaced.
If your pad shell is wearing thin, fix it or upgrade. The foam inside is only as good as what’s holding it together.
If your pads can’t handle the landing, fix that first.
