The Siren Bib is for those who prefer less fabric up top. You won’t sacrifice durability. But you will get a lighter weight, more breathable bib for backcountry touring and, thanks to eVent DV Expedition fabric, it’ll keep you cool by releasing heat before you sweat. The Siren is streamlined and durable with simple design, so you can focus on the day’s objective. A kangaroo front pouch stores your essentials, outer thigh vents release steam, and reinforced cuffs keep you feeling tough.

Emily Rodriguez –
I love the Siren Bib for its versatility. It works great for both resort and backcountry skiing. The material is breathable yet warm.
David Kim –
The Flylow Siren Bib is well-made, but the sizing runs a bit large. I had to exchange for a smaller size, but otherwise, it’s great.
Jessica Lee –
These bibs are worth every penny. The waterproofing is top-notch, and they’ve held up through multiple seasons of heavy use.
Chris Wilson –
The Siren Bib is comfortable and functional, but the waist adjustment could be better. It tends to loosen over time.
Amanda Carter –
I’ve tried many bibs, and the Flylow Siren is by far the best. The fit is flattering, and the material is tough yet flexible.
Ryan Miller –
Great bibs for cold weather. The insulation is just right, and the reinforced knees are a nice touch for durability.
Lisa Brown –
The Siren Bib is stylish and functional, but the zippers can be a bit finicky. Otherwise, it’s a solid choice.
Daniel Harris –
These bibs are perfect for long days on the mountain. The ventilation zips are a lifesaver when the temperature rises.
Olivia Martinez –
The Flylow Siren Bib is a great investment. It’s kept me dry and warm in some of the worst conditions.
Kevin Taylor –
Solid bibs overall, but the price is a bit steep. If you can afford it, though, they’re worth it.
