How to Pack a Paraglider Wing Perfectly: The Concertina Bag Guide

Every paraglider pilot knows the moment: you’ve just landed after an incredible flight, the mountain is still echoing with your whoops of joy — and now comes the less glamorous part. Packing your wing.

Done carelessly, you risk damaging delicate cells, misaligning ribs, or creating creases that haunt your next flight. Done right, your paraglider stays in peak condition, flies predictably, and lasts significantly longer.

The Concertina Bag is designed specifically for this task. Its accordion-style folding system transforms wing packing from a rushed chore into a precise, repeatable process that protects your gear every time.

Why Packing Method Matters

Your paraglider canopy is a precision piece of engineering. Thousands of interconnected cells, carefully calibrated to inflate and generate lift. Rough handling — hasty stuffing, sharp creases, uneven pressure — can:

• Weaken rib seams over time, increasing the risk of cell failure
• Create uneven wear patterns that affect flight behaviour
• Damage lines caught in pinched fabric
• Reduce lifespan of an expensive piece of kit

A good packing method isn’t just about fitting your wing into a bag. It’s about preserving performance and maximising longevity.

The Accordion Folding Technique Explained

The core principle behind the Concertina Bag is accordion folding — sometimes called the “sausage roll” or “concertina fold.”

Rather than stuffing or loosely rolling, accordion folding works like this:

Step 1: Lay Your Wing Flat

Start with the wing fully spread out on a clean, smooth surface — a grassy landing field is ideal. Sort the lines to one side (risers and brake lines together) so they’re out of the way.

Step 2: Fold in the Walls

Starting from one tip, fold the outer cell walls inward toward the centre line, creating a narrow strip. Each fold should be even and consistent — roughly 20-30cm wide.

Step 3: Accordion Through the Span

Continue folding the wing in regular sections, working your way along the span like pleats on an accordion. The goal is uniform compression — no thick lumps, no thin gaps.

Step 4: Roll or Fold to Length

Once you’ve accordion-folded the entire wing, fold or roll the bundle to fit your bag’s dimensions. The Concertina Bag’s specific cut and compression system accommodates this folded shape perfectly.

The Key Advantages of Accordion Folding

1. Even Weight Distribution

Because each fold is uniform, the pressure on the fabric is spread evenly. This prevents the thin spots and compressed lumps that come from informal stuffing.

2. Protects Leading Edge

The leading edge takes the most stress in flight. Accordion folding keeps it straight and supported, rather than bent or kinked.

3. Faster Packing

Once you’ve done it a few times, accordion folding takes less than five minutes. The Concertina Bag’s shape guides the process — it’s almost impossible to fold “wrong.”

4. Less Line Tangling

Organised folds mean fewer lines getting snagged. You’ll spend less time untangling before your next flight.

Why Use a Concertina Bag?

The Concertina Bag isn’t just a fabric sack. It’s a structured packing system designed around accordion folding:

• Tailored dimensions that match the folded wing shape
• Compression-friendly materials that protect without crushing
• Separate compartments for lines and risers
• Durable construction that handles repeated use

Whether you’re at a competition, on a vol-biv adventure, or just finishing a casual XC, the Concertina Bag keeps your wing protected in your rucksack, car boot, or equipment locker.

Common Packing Mistakes to Avoid

Even with a Concertina Bag, pilots still make packing errors that shorten wing life:

❌ Folding on Rocky or Abrasive Ground

Always lay out a ground sheet or flysheet before packing. Stones and grit embed in the fabric and cause micro-tears.

❌ Leaving the Wing Damp

Moisture trapped in packed fabric leads to mildew and degradation. If your wing is damp, spread it out to dry before packing — even if it takes an extra hour.

❌ Over-Compressing

Your wing needs a little breathing room. Over-tight compression strains seams and can deform cell openings.

❌ Ignoring the Lines

Lines should be neatly stowed before you fold the wing. Tangled lines pulled through the canopy during folding cause real damage over time.

❌ Packing Immediately After Landing

Hot fabric is more vulnerable. Give your wing a few minutes to cool before packing — especially in summer.

How Often Should You Repack?

Competition pilots and frequent flyers should repack every 2-3 days if the wing is stored long-term. For occasional flyers, once a week during active periods is fine.

Never leave a wing packed for more than 2-3 weeks without unpacking and re-inspecting it. Long-term compression can set creases into the fabric.

Choosing the Right Size Concertina Bag

Concertina bags come in size categories that correspond to wing sizes. Getting the right fit matters:

• Too small: you’ll over-compress the wing to force it in
• Too large: the wing shifts during transport, causing uneven wear

Check your wing’s size (typically EN/LTF rated from XS to XXL) and match it to the bag size. The Concertina Bag at Yowfly is available in sizes that cover the full range of recreational and competition wings.

Packing for Travel and Transport

If you’re flying with your wing or transporting it regularly, add these steps:

1. Use a double-bag system — Concertina Bag inside a padded holdall

2. Deflate the roll slightly before tightening the compression straps

3. Keep the manual inside the bag for reference

4. Check airport restrictions — some airlines have specific requirements for paragliding equipment

The Bottom Line

Perfect wing packing isn’t about speed — it’s about consistency and care. The accordion technique used with the Concertina Bag makes it easy to pack your wing the right way, every time.

A wing that goes into storage well-packed comes out flight-ready. A wing that’s stuffed carelessly… doesn’t.

Invest three minutes in proper packing, and your paraglider will thank you with hundreds of smooth, safe flights.
