If you’re prone to breaking your Nalgene caps, the N-Gen is made from an extra-rugged copolyester that’s even more durable than the classic lids. And even if you do manage to break it, Nalgene covers damaged lids under their lifetime warranty. Similar to the AutoSpout, the Contigo AutoPop lid has a push button release. But instead of a pop-out straw, it has a pop-off cover over a narrow mouth drinking spout.

For starters, the Paravalve’s Dual Ball Valve is completely leak-proof when closed. Which is great for my Nalgenes, since they don’t fit in my car’s cup holders and often just lay on my passenger seat between drinks. While Contigo doesn’t appear to sell replacement lids, their lids work flawlessly with Nalgene Bottles if you happen to already have them. From lids that make drinking just a little more convenient to lids that fully convert your Nalgene into a hands-free hydration system — there’s a lid for everyone. Now you may be asking yourself, why don’t I just get a narrow mouth Nalgene instead of a wide mouth with a capCAP+ lid?And lastly, we have the classic Nalgene lid. It’s simple, durable, easy to clean, and much less likely to grow mold than most other lids. The Nalgene MultiDrink cap offers two functional ways to drink from your Nalgene Bottle — equipped with both a narrow mouth drinking spout and a slide-out straw. The Nalgene Easy Sipper has been the most requested product that Nalgene have had over the years. Most people love the convenience of the wide mouth bottle when it comes to filling and cleaning but sometimes find it hard to drink from. Brew tea or coffee on the go with this simple drop in filter that fits most wide-mouth water bottles such as Nalgene.

Nalgene – The original water bottle. BPA Free. Nalgene – The original water bottle. BPA Free.

Simply drop in the filter, add coffee or tea leaves, fill your bottle with hot water, and let it do its thing. Dual ball valve makes this straw lid leak proof when closed and effortless to drink out of when opened. Has a smart vent to depressurize bottle and it's also insulated and easy to clean. This is one of the reasons my youngest son always chooses the narrow mouth Nalgene over the wide mouth to take to school. But I personally prefer the wide mouth because it's easier to clean and easier to put ice into. We’ve all been there before with wide mouth bottles. You’re taking a drink and tilt the bottle just a bit too far and water comes pouring out from around your mouth.

Secondly, when open, the Dual Ball Valve provides effortless drinking thanks to large air and water paths that allow for easy, unrestricted sipping. Ultimately, the best lid for a Nalgene Bottle comes down to your own preferences and the way you use your bottle. I find myself swapping between several lids regularly depending on what I’m doing. The Chute Mag Cap by CamelBak is another lid that comes equipped with a narrower mouthpiece. But the Chute Mag stands apart from the others because its spout is still wide enough to chug. The Paravalve High Performance Straw Lid offers a flip-out straw with a Dual Ball Valve design that provides a few unique advantages when compared to other straw lids. Like the capCAP+, the Nalgene Easy Sipper is designed to make drinking from a wide mouth Nalgene a lot easier. But unlike the capCAP+, the Easy Sipper is a simple insert that can be used with the classic Nalgene lid or any other cap.
