Leakproof 40oz Cruiser Lid

Twist-and-lock is so simple that I almost didn't trust it, but I've shaken this thing upside down over the sink and not a single drop came out. The seal is impressively tight, and I'm finally free to toss my 40oz in my bag without worrying about a soaked laptop.

Took my 40oz Cruiser on a bumpy bike ride with this lid and not a drop came out—that twist-seal really holds. It's a simple swap but makes a huge difference for daily carry.

I was so relieved when the twist seal actually locked in — not a single drop leaked in my bag all day. Finally a lid that does exactly what it promises without any fuss.
