The single biggest reason to buy is the fabric blend and construction: an 82% polyester \/ 18% spandex mix with LYCRA Xtra Life that delivers a smooth, hydrodynamic feel, reliable compression, and quick-dry performance that stands up to repeated pool use. It is presented as a practical, versatile jammer rather than a race-only suit, and it balances comfort, fit options, and value.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFabric blend:\u003c\/strong\u003e The 82% polyester and 18% spandex construction gives a stretchy, hydrodynamic surface that moves with the body during laps and cross-training.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLYCRA Xtra Life:\u003c\/strong\u003e Built-in LYCRA Xtra Life helps the jammer hold shape and resist chlorine so it keeps its fit longer under regular pool use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression and comfort:\u003c\/strong\u003e The 4-way stretch and moderate compression provide muscle support during training while remaining comfortable for extended wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure fit:\u003c\/strong\u003e An internal drawstring and liner offer reliable coverage and privacy, useful during swimming, running, or ocean activities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-dry, multi-use design:\u003c\/strong\u003e The polyester 240 GSM fabric is moisture-wicking and dries quickly, making the jammer suitable for swim, surf, kayak, or using as a compression liner under boardshorts and wetsuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPF and resistance:\u003c\/strong\u003e UPF 50+ protection and chlorine-resistant treatment help preserve color and fabric performance outdoors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Onvous Mens Jammer is ideal for recreational and fitness swimmers who train laps, join masters practice, or want a versatile suit for beach workouts and cross-training.
