A versatile classic

The O-Type envelope combines the engineering efficiency of the popular Viva and the advertising effectiveness of the smoother N-Type envelopes…a balloon for all! This was ideally suited to the sports pilot or promotional work but has now been generally superseded by the need for an artwork-friendly, smooth surface balloon, like the fabulous Z Type. 

These envelopes are horizontally cut to 12 bulbous gores, attached to twelve stainless steel flying wires. 

O-Types can be made from our durable RipStop (69gsm) or our high tenacity superlight RipStop (38gsm - that's nearly half the weight of standard computer paper!). Cameron Balloons designed Hyperlast is also available throughout our range of hot air balloon envelopes.  

Looking for the perfect Hopper envelope?

Both the Cameron O-26 and Cameron O-31 are perfect for those pilots that are serious about enjoying the freedom of flight and experiencing an enhanced adrenaline high. With unequalled reputation for quality, a Cameron Hopper offers exciting opportunities for leisure, sport and commercial teams.

New Hoppers are made from our stunning Superlight RipStop (38gsm) - that's nearly half the weight of standard computer paper... 

With an envelope weight starting from only 29kg, this stunning advance in fabric technology introduces even lighter ballooning from Cameron Balloons Ltd. Add this to the Neo Hopper base unit & burner, an aluminium 'Alugas' 40 cylinder or a Titanium 60 cylinder and you have yourself a 'Record-Breaking' possibility. Superlight ballooning is likely to get even more interesting from now on...

Envelope options

  • Click here to see our fabric colour charts to see the extensive range of colour options that are available.
  • Special colour dye fabrics are also available upon request. This can be the perfect solution for colour matching your desired Pantone or corporate shade. 

Envelope Options

    • Superlight fabric option is available at no extra cost.
    • Internal Load-tape construction available.
    • Envelope ‘windows’ in Cameron see-safe fabric can be positioned to provide sight of the sky or balloons above.
    • Additional registration marks and country flags can be applied.

Why not consider Superlight?

By far the greatest weight saving can be made by using a lighter envelope fabric. For the same price as our regular ripstop, the weight of your balloon can be up to 30% depending on the type and size of balloon required. 

Other specifications like flat-webbing tapes, 3mm diameter flying wires and lightweight crown-line will all compliment your choice.

Why not include Kevron load tapes? they are immensely strong and very light weight, offering a further 4% reduction in weight from our standard envelopes. These 'tapes' are encapsulated within the seams, to protect them from damaging UV rays.

Optional equipment

    • Choice of deflation systems - RDS (Rapid Deflation System), ParaPlus or Standard Parachute.
    • Single, twin turning vents available.
    • Lightweight polyester loadtapes available.
    • Kevron loadtapes available. A Kevron loadtape consists of woven Aramid fibre webbing encased in fabric sheath which replaces the conventional polyester or nylon tape for weight advantage.
    • Kevlar flying cables are a lightweight option to be considered in place of stainless steel flying wires.
    • Shaped banners with or without artwork are available, tailor-made to hug your balloon envelope’s surface. 

Introducing ParaPlus deflation.

      • This is a two-line control system for more controlled venting in Racers and Sport envelopes.
      • The second line can be pulled into the basket and held to inflate without tabbing the parachute in.
      • The system offers a much lighter venting action.
      • Finally, the second line can be used to adjust the parachute position. The rigging and pressure in the envelope re-seal the parachute to a satisfactory level, however, due to the very light action, the additional line offers our pilots a fail-safe tidy.


What people are saying…

Customer promise

Each balloon envelope is built from individual “blocks” of fabric called panels, which are grouped into vertical “stripes” known as gores.

All balloons require regular maintenance and servicing which keeps balloon-systems working well and enables years of happy flying – maintenance usually takes place after 100 flying hours or 12 months whichever is sooner. Airworthiness Inspection & Maintenance Manual (UK).

Cameron Balloons fabrics have anti-mould, anti-mildew and anti-UV degradation agents added to them to prolong the life and colour of our balloons. Fluorocarbon is also added to the outside face of the fabric to defend the fabric from moisture, dirt and debris.

Excellence really is our lowest standard; exemplary quality, proven reliability and attentive service are some of Cameron Balloons key and constantly striven for company goals.

Our range of complete balloons, airships and lighter-than-air craft are all fully certified and approved.

Cameron Balloons also offers assurance – An ESCROW account is available – guaranteeing that your deposit payment is safe with us.
