Speedo Men's Standard Swimsuit Jammer Endurance+ Splice (Style VCRP)

Our review of the Speedo Disco Boom Splice Jammer finds it best suited for regular lap swimmers and club athletes who want a durable, chlorine-resistant training jammer with a bold look. The single biggest reason to buy is the ENDURANCE+ fabric, Speedo's longest lasting chlorine-resistant material, which delivers consistent shape retention and sun protection for routine pool work. The fit can be variable so buyers should check sizing notes, but for swimmers after comfort, a secure waistband, and a lined jammer that stands up to frequent chlorinated use, this model is a sensible, attractively styled option.

Key Features

• ENDURANCE+ fabric: Provides strong chlorine resistance and long-term shape retention so the jammer stays usable through many training sessions.
• Fully lined construction: Offers added comfort and modesty for daily lap swimming without sacrificing a streamlined profile.
• Drawcord at waist: Ensures a secure, adjustable fit during starts, turns, and interval work.
• ProLT fabrication: Combines poly and spandex for a balance of stretch and durability that supports stroke efficiency in the water.
• UPF 50+ protection: Shields skin from sun when training outdoors, making this jammer practical for mixed pool and open-deck sessions.
• Team splice design: A distinctive Disco Boom splice appearance that stands out on deck without compromising performance.

Who It's For

The Speedo Disco Boom Splice Jammer is a good match for competitive swimmers and regular lap swimmers who need a reliable training jammer that resists chlorine and keeps its shape session after session. It also suits coaches or swim teams wanting a recognizable team-color look with practical sun protection for outdoor pools.

Swimmers who require a very compressive race suit or those who prefer a consistently precise sizing fit might look elsewhere; some customers report that sizing runs smaller for certain body types and a few have noted seam durability concerns after heavy use.

Pros & Cons

Cons
