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 This was ideally suited to the sports pilot or promotional work but has now been generally superseded by the need for an artwork-friendly, smooth surface balloon, like the fabulous Z Type.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 that weighs from only 29kg, this stunning advance in fabric technology introduces even lighter ballooning from Cameron Balloons Ltd. Add this to the Millennium Hopper base unit & burner, which weighs just 20kg, and an aluminium 'Alugas' 40 cylinder weighs at 13kg (34kg full) or a Titanium 60 cylinder at 10kg (40kg full)... And you have yourself a 'Record-Breaking' possibility... Superlight-weight ballooning is likely to get even more interesting from now on...

Why not consider Superlight?

Due to the large percentage of a hot-air balloon envelope being fabric, a fundamental key is the saving that can be made by using a lighter ripstop. This could be up to 30% depending on the type and size of balloon required. This gives the greatest saving by far.

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

To continue with the weigh-saving, 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. We encapsulate these 'tapes' within the seams, to protect them from damaging UV rays. Any Kevron load tape that can not be within the seam is feed securely through a tubular, outer tape to ensure it's longevity.

We are very pleased to announce that our Superlight fabric is the same price as our regular Ripstop (69gsm). A range of 49gsm ripstop fabric is also available, subject to a small supplement charge. Please call or email for further details - sales@cameronballoons.co.uk

Why not chat with our sales team about which fabric is right for your balloon or project, we would be delighted to provide ideas, suggestions, case-study experience, customer testimonials and fabric samples.

  • 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.

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.

The O-Type shape has a bulbous surface creating a wonderfully classic balloon that so many adore. 

Our guarantee period for superlight fabric is four years (48 months) or 250 hours of flight time, whichever occurs first. Regular ripstop nylon is five years (60 months) or 300 hours of flight time, whichever occurs first. For Hyperlast fabric incorporated into the balloon envelope is six years (72 months) or 600 hours of flight time, whichever occurs first.

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).
