18″ Arena Monoflap Jump – Saddle Details

A Close-Contact Jumping Saddle

The Arena Monoflap Jump is designed for riders who like to feel close to their horse.

With only one layer between the rider and the horse, the monoflap construction gives a particularly direct feel through the leg. It is a popular style for riders who want their leg position to remain clear and unobstructed when working over fences.

The seat has been designed to provide a balanced position without feeling excessively restrictive. Fixed knee and calf blocks add support without taking away from the rider’s ability to move with the horse.

Whether you’re schooling at home, working on your jumping technique or heading out to competition, the Arena offers a practical combination of support and freedom.

Adjustable Arena Elastiflex Tree

One of the useful features of this saddle is its adjustable Elastiflex tree.

The saddle can accommodate gullet widths from Narrow through to Extra Wide, and this particular saddle is supplied with an XW bar.

That adjustability can be useful when your horse’s shape changes over time. However, an adjustable gullet should not be viewed as a guarantee of fit. The saddle still needs to be assessed on the individual horse.

Your horse’s back shape, wither profile, shoulder movement, topline and the rider’s position all need to be considered.

For that reason, we recommend having the saddle checked by a qualified saddle fitter before regular use.

CAIR Cushion System

The Arena Monoflap Jump incorporates the CAIR Cushion System, designed to provide a flexible panel arrangement beneath the saddle.

The panels are soft and designed to follow the horse’s back while providing a comfortable interface between horse and saddle.

The Easy-Change system also gives a fitter additional options for making appropriate fitting adjustments.

This combination makes the Arena particularly interesting for owners who want a jumping saddle with some room for adjustment rather than a completely fixed configuration.

Fixed Knee and Calf Blocks

The external knee and calf blocks provide useful support when jumping.

They help give the rider a consistent reference point for the lower leg, particularly when riding over fences or working on a more forward position.

The padded knee inserts add another layer of comfort without making the saddle feel unnecessarily bulky.

The ergonomic stirrup bar is another practical touch, helping the rider maintain a natural leg position.

Condition – Used Grade 4

This Arena Monoflap Jump is a used saddle in Grade 4 condition.

Overall, it is in very good used condition, although there is some evidence of previous use. The right flap has a light scratch/wear mark, which should be visible in the product photographs.

We believe it is important to describe used saddles honestly rather than simply calling everything “excellent condition.” Please take time to study the photographs alongside the written condition description before ordering.

Our View of the Arena Monoflap Jump

The Arena range offers an appealing combination of modern saddle design, adjustability and competitive pricing.

This particular monoflap model is especially suited to riders who prefer a closer feel and like having supportive external blocks beneath the leg.

The adjustable gullet is a useful feature, while the CAIR and Easy-Change systems give you additional fitting options.

For an 18″ saddle, it also provides a good amount of room for riders who prefer a larger seat.

In our view, it is a versatile jumping saddle for riders looking for support, adjustability and a close connection with their horse.

Who Might This Saddle Suit?

This saddle could be worth considering if you:

• Prefer a monoflap jumping saddle
• Like a close-contact feel
• Need an 18 inch seat
• Prefer external knee and calf blocks
• Want an adjustable gullet system
• Ride regularly in the arena
• School over fences
• Compete or attend jumping shows
• Need a saddle that can accommodate a wider range of gullet settings

The saddle has a standard wither profile, but suitability always depends on the individual horse.

Gullet and Fitting Information

This Arena is adjustable from Narrow to Extra Wide and currently has an XW gullet bar fitted.

The saddle is intended to work with the Arena Easy-Change fitting system.

If your horse is changing shape because of training, seasonal condition changes or changes in muscle development, an adjustable saddle can provide useful flexibility.

However, please don’t choose the saddle based on the gullet measurement alone. A saddle can have the correct gullet width and still be unsuitable because of its panel contact, balance, length or overall tree shape.

Professional saddle fitting is always recommended.

Saddle Care

Leather responds well to regular, sensible care.

After riding, remove dirt and sweat before they have a chance to build up on the leather. Use a suitable equestrian leather cleaner and follow with an appropriate leather conditioner or balsam when required.

Pay particular attention to areas that experience more wear, including:

• Stirrup leather contact areas
• Girth straps
• Billets
• Knee blocks
• Flaps
• Seat

Avoid excessive moisture and store the saddle somewhere dry and away from direct sunlight.

Regular cleaning isn’t about making a saddle look perfect all the time. It’s about keeping the leather supple and preventing dirt and sweat from gradually damaging it.
