Beneunder UPF 100+ Wide Brim Sun Hat vs Sunday Afternoons Vivian Hat

The Beneunder BM530 is the stronger sun blocker: UPF 100+, a 12cm brim that wraps the cheeks and jaw, a reflective underlayer and a cooling sweatband, and owners rate it 4.9 across 195 reviews. The Sunday Afternoons Vivian is the more conventional hat, with UPF 50, a floppy brim, a moisture-wicking sweatband and a chin strap, and its smaller review base is perfect-scored. Pick the Beneunder for intense sun and full face coverage; pick the Vivian for a softer, packable trail hat with a chin strap.

  • Choose the Beneunder BM530 if you want maximum UV block, full cheek and jaw coverage, and a cooling band for long hours in strong sun.
  • Choose the Sunday Afternoons Vivian if you prefer a soft floppy brim, a wicking sweatband and a chin strap for windy hikes and everyday wear.

Questions and answers

Which hat is better for very strong sun?
The Beneunder BM530. Its UPF 100+ rating, blackout lining and 12cm wrap-around brim cover more of the face and jaw than the Vivian's UPF 50 floppy brim.
Which stays on better in wind?
The Sunday Afternoons Vivian, because it has an adjustable chin strap. The Beneunder relies on a velcro head strap only.
Is the Beneunder worth stepping up to over the Vivian?
If you spend long hours outdoors in harsh sun, yes. The higher UPF, wider brim and cooling band are real advantages. For casual wear the Vivian is simpler and easier to live with.
Which is cooler on the head?
The Beneunder has a cooling sweatband and a reflective underlayer, and owners say it feels cool in heat. The Vivian relies on ventilation and a wicking band, which suits moderate heat better.
Can either hat be washed?
The Beneunder is not machine washable, so spot clean it. Sunday Afternoons does not state machine washing for the Vivian either; hand wash and air dry to be safe.
Which fits a ponytail?
The Beneunder BM530 has a ponytail hole. The Vivian does not.
