FireFly® PRO WATERBUG SOLAS

The Firefly® PRO WATERBUG is a SOLAS-approved strobe light with a built-in water activation feature that will automatically activate once submerged.  

With four (4) activation functions, toggle between the armed mode for automatic water activation, ultra-bright strobe light, SOS strobe or the Steady-On feature feature to visually alert Search and Rescue of your location. 

The innovative new wide light emission LEDs produces a 360° beam of light (41 candela) allowing for visibility of over 3 miles.  The Cool White light has no yellow tinting which allows for a more visible light beam that can be seen at greater distances.  With an energy efficient microprocessor and redesigned electronics, the Firefly® PRO WATERBUG SOLAS boasts maximum operation life in the harshest of conditions.  

With a single set of AA Lithium batteries, the Firefly® PRO WATERBUG SOLAS will continuously strobe for over 56 hours or use the Steady-On feature for 28 hours of usage. This exceeds USCG and SOLAS requirements by over 48 hours.

The new compact size will easily fit inside an inflatable life jacket or pocket for comfortable wear-ability.  The military spec casing is rugged enough to withstand years of abuse and the harshest environments.  The two lashing loops and included Velcro strap make mounting the Firefly® PRO WATERBUG SOLAS to your life jacket, belt or pack extremely easy so that the strobe light can be readily accessible the moment you need it.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.

A nice, comfortable t-shirt with a bit higher moc neck
Size: Small, Color: White
I wear tee shirts a lot, but, because I need something a little warmer at times I wondered if such a thing as a moc-neck tee existed. This shirt is soft and comfortable, not tight but more tee shirt- like in fit.
