Description
xThe Oblivion features internal bonding specifically positioned to provide maximum lift in the water. This precision engineering works alongside the suit’s latest fabric technology to mould tightly to the body. The result is a locked-in feel that supports every stroke without restricting movement.
Additional leg compression is built into the Oblivion to maintain optimal body position in the water, particularly under the fatigue of a hard race effort. Ultrasonic bonding and high-performance seam tapes isolate key muscle groups for targeted support. The suit is designed to hold its shape and compression from the first stroke to the final touch.
Resistance is reduced with an advanced water-repellent formula applied to the surface of the Oblivion to achieve improved speed through the water. This finish works in tandem with the suit’s compressive structure to streamline the swimmer’s profile. Every detail is engineered to shave time off your race.

Yes, the Funky Trunks APEX Oblivion is World Aquatics approved, so it can be worn in sanctioned competitive pool events at all levels.
Because this is an elite compressive race suit, fit is critical and sizing can differ from your usual training suit. We strongly recommend consulting our Funky Trunks Mens Apex Size Guide before ordering, and noting that the Oblivion is intended for swimmers with experience fitting compressive suits.
The Oblivion is an elite race suit, not a training jammer. It features maximum compression fabric, targeted internal bonding for lift, additional leg compression, ultrasonic bonding, and a water-repellent surface formula. These technologies are designed to improve body position and reduce drag in competition, rather than simply providing comfort across repeated sessions.
Race suits require careful handling to maintain their compressive properties and surface treatment. Please follow our full product aftercare guide guidance to get the most from your Oblivion.

Allens Swimwear is a family-run business founded in 1976 by Dennis Allen and his daughter Linda Beal. It started from a genuine need. “With 2 swimmers in the family it was often difficult to find the right kit, so dad and I took the plunge and started selling to local swimmers at our local pool in Kingsbury out of a suitcase and we’ve never looked back.” Today, Linda, her husband Richard, and three of their children Danny, Will and Jenna still run the business together. The suitcase may be long gone, but the founding principle of helping swimmers get the right kit remains exactly the same.

UK, US, and AUS sizes are equivalent for this range. Always measure waist and hips for the most accurate fit. Racing suits are compression garments — if between sizes, speak to a member of staff at Allens. Do not use training swimwear sizing as a guide for racing suits.
Measure your waist and hips in centimetres and match to the size table above. UK, US, and AUS sizes are equivalent for this range. Racing suits are compression garments and will feel tighter than training swimwear — do not size up solely to avoid the compression feel. If your measurements fall between two sizes, speak to a member of staff at Allens for advice.
The Apex Viper is the entry point to the APEX range — a World Aquatics Approved jammer with mid-level compression, warp knit fabric, water-repellent finish, and gripper tape. It is suited to competitive swimmers at all levels. The Apex Predator X adds internal X design bonding around the hips and ultrasonic bonding for greater compression and muscle isolation. The Apex Oblivion is the most advanced suit in the range, with internal bonding for lift, maximum compression, and additional leg compression to maintain body position under fatigue — designed for elite swimmers with experience in compressive race suits.
Yes. All three APEX jammer models — the Viper, Predator X, and Oblivion — are World Aquatics Approved for use in sanctioned competitive swimming events. Always check with your governing body or meet officials if you are unsure whether a specific suit is permitted for your competition.
APEX jammers are designed for competition use only. Using them for regular training will significantly reduce their lifespan and compromise their hydrodynamic and compression properties. For training, we recommend the Funky Trunks Training Jammer, which uses ECO C-Infinity chlorine-resistant fabric built for regular pool use.
World Aquatics (formerly FINA) is the international governing body for competitive swimming. A World Aquatics Approved suit has been tested and certified to meet the regulations for use in sanctioned competition, including restrictions on buoyancy, surface texture, and coverage. All APEX jammers in this range carry this approval.
A racing jammer should feel tight and compressive — considerably more so than a training jammer. There should be no excess fabric, bunching, or gaping. The waist and leg grippers should sit flat against the skin. The compression is intentional and designed to support the muscles, reduce drag, and improve body position in the water. If the suit is uncomfortable to the point of restricting breathing or circulation, try the next size up and speak to our team.
Rinse thoroughly in cold fresh water immediately after every use. Do not machine wash, tumble dry, wring, iron, or expose to direct sunlight for extended periods. Store flat and dry, away from sharp objects. Proper care will preserve the water-repellent coating, compression properties, and bonding for longer.
If you are new to racing suits or competing at club level, the Apex Viper is the ideal starting point — it is World Aquatics Approved and offers mid-level compression with all the key race suit features. The Predator X suits swimmers competing at regional or national level who want greater compression and bonding. The Oblivion is designed for elite swimmers with experience in compressive race suits competing at the highest level. Speak to our team at Allens if you would like help choosing the right suit for your level.
