Varlion Bourne Summum Prisma Airflow S 2024

Varlion Bourne Summum Prisma Airflow S 2024 is an attacking racket with a firm, demanding response. Its diamond shape and high attacking intent are clear from the first overhead: this is built for players who want to accelerate the ball and take control of the net.

I found it more precise than many hard diamond rackets, but it does not give away much free help. Clean technique gets rewarded. Late contact, passive blocks, and lazy defensive swings do not.

The “S” core is designed for warmer conditions, and that matters. In heat, it keeps a compact response rather than turning overly soft or springy.

Technical analysis

Shape & balance

The diamond mold places the sweet spot higher in the face, which suits aggressive volleys, overheads, and finishing shots. It feels quick enough through the air for a racket in this category, helped by the Prisma frame profile and Airflow-style construction, but it is not head-light.

That balance gives the racket real authority above shoulder height. I could generate a heavy ball without having to overwork the swing. The trade-off is obvious at the baseline: off-center contact is less forgiving, especially when defending fast balls at the body or playing under pressure after the glass.

Materials & construction

The frame uses bidirectional carbon tubing, while the faces combine 12K carbon, plain 3K carbon weave, and a thin fiberglass layer. That mix gives the contact a firm, crisp edge without making it completely dead. There is some give in the face, but it is a controlled response rather than an easy trampoline effect.

Inside sits the S hard rubber core, a hard feel formulation intended for temperatures above 25°C. In warm conditions, the ball comes off with speed when I accelerate properly. In colder weather, I would expect it to feel noticeably firmer and less forgiving, particularly on defensive shots where I am relying on the racket for ball exit.

On-court feel

Baseline play

From the back of the court, this racket asks me to prepare early and hit through the ball. Defensive lobs can be very accurate because the face does not over-launch the ball, and low-driven lobs carry well when I commit to them.

Blocks are stable, but not automatic. The smaller effective sweet spot means that a loose wrist or contact near the edge can leave the ball short. Players who prefer a soft racket that absorbs pace and sends the ball deep with minimal effort may find the Bourne S too strict.

At the net

At the net, its character makes more sense. Firm volleys come off flat and penetrating, with enough stability to redirect a hard ball without the frame twisting much. I particularly liked it for attacking the middle and for finishing a short chiquita with a controlled punch volley.

Touch shots require restraint. The response is direct, so drop volleys and softer angles need good hands rather than a big helping window from the racket.

Bandeja and víbora

The higher balance works well on a bandeja and víbora. It carries momentum through the ball and lets me hit a more aggressive, lower trajectory without feeling as though the racket stalls in the swing.

Still, this is not a racket that makes defensive overheads easy. If I am stretched behind the ball, the firm core can make it harder to produce a relaxed, high defensive lob. It wants active technique and confident acceleration.

Conclusion

I would put the Bourne Summum Prisma Airflow S 2024 in the hands of an advanced player who builds points to reach the net and wants a hard, offensive response in warm conditions.

It brings power, direct volleys, and serious overhead potential. In return, it asks for cleaner contact than a softer or more forgiving racket. Beginners, players with inconsistent timing, and anyone wanting easy defensive ball exit should look elsewhere.
