Siren Bib Pant

Embark on your dawn patrol mission or post resort pow day tour in the super lightweight FlyLow Siren Bib Pant.

To further keep you protected but moving effectively, the Siren also features a half-height bib, adjustable suspenders, and large outer leg vents that let you dump excess heat during extremely rigorous periods of time.

I write this review in August without testing the bibs in weather, but I wanted to share the fit since there is limited reviews. I’m very pleased with the quality and fit of the bibs. I’m 5’4, athletic build with a smaller waist. My largest concern was seeing that the foxy bibs fit some individuals very strange. The siren allows for a looser fit ( I purchased a M although I may have been able to fit in a s) which is what I prefer. The crotch does not hang long and while the waste/medium bib doesn’t have a snug fit it would provide space for base layers and insulation. The length looks like it would work well for both shorter and taller females. I’m very happy I pulled the trigger on these bibs.

I love these Flylow bibs! I have the Foxy and much prefer the mobility of the Siren. While I love these colors, I hope they offer black as well, soon. Thanks for making stretchy ski gear!

I've been looking for simple, comfy bibs for forever, and I finally found them. The Siren bibs are lightweight, fit loose and comfortable but not too baggy. The pockets are big enough to fit a beacon. The material is super high quality and has held up to many days of touring and shoveling already. They're easy to unzip to go to the bathroom, the pant cuffs are just right, and the bib straps are nice and long with lots of adjustability. So glad I found them! I am 5'8", 140 lbs and the Medium is perfect.


Are the straps compatible with a backpack? It looks like the adjustment piece lines up right where a backpack strap would go.
