Classic Flip Seal Sport Cap

Best drink-through cap out there

I really enjoy these caps. The straw with flip spout makes trail water breaks quick and easy! No fooling with the cap. No cranking your neck. No spills. Got 4 for all of my bottles. I learned not to put the bottles in my pack. Gear can press on the flip knob. That allows water to leak out of the vent hole.

Like having a metal straw option

I like it and the cap doesn’t leak, I wish the straw had the lip like the kids straws that keeps it in place. It sometimes separates from the top when I’m filling my water bottle then I have to fish out the straw from the bottle. I’m a nurse and even though I wash and wash my hands I’d rather not stick my finger in my water bottle if I can help it! It also sometimes has such a strong seal that it creates a vacuum and I can’t drink water until I loosen the cap some.

Caps

I had to replace all my son’s flip caps because the old ones ripped because the straws were not fitting. This is much better and I love the telescope straw. Sometimes the straw falls out of the cap, but at least they don’t tear the rubber.
