The products were very good
The products were very good. More than I’d expected them to be. The color of the diaper bag is beautiful and I know my daughter in love will be happy with it.

User recommends O'Brien for comfort and mobility
I have the O'Brien Flex V-Back and it's by far the most comfortable PFD I've used. The V-back really does allow for more movement and it doesn't ride up like cheaper vests. The zipper and dual belts keep it secure. Perfect for kayaking.

O'Brien user shares positive experience across watersports
Just got the O'Brien Flex V-Back for paddleboarding and it's awesome. Super lightweight, dries fast, and the wide armholes don't restrict my paddle strokes. Feels like I'm wearing nothing. Highly recommend.

Kayak angler compares O'Brien to NRS and Stohlquist
For kayak fishing, I prefer the O'Brien Flex V-Back over NRS. It's more flexible and less bulky. Tried a Stohlquist too but the O'Brien fits better and has a lower profile for casting. Only downside is it can get a bit warm on hot days, but overall it's my go-to.
