Paired with Klean Kanteen's Insulated TKWide bottles, the TKWide Café Cap is truly leakproof and gives you on-the-go access to your hot or cold drink with a simple turn of the lid. Together, this cap and bottle duo stand out as a well-made, everyday, versatile option, especially for coffee or tea drinkers.

My middle-school-age daughter and I tested and reviewed the 16-fluid-ounce Insulated TKWide bottle last year. Despite our extensive home collection of bottles she was excited to test that bottle specifically for its cafe style cap, as she had asked for a bottle with that type of cap for years. While the bottle you choose matters in terms of volume and insulation capability, its cap will be put on and taken off your bottle repeatedly and is key to preventing leaks. So, we figured this cap deserved its own review, because without a cap, a bottle is just a tall cup.

Excellent design and material allows this splash guard to fit a wide variety of wide mouth bottle sizes and brands.

I have used a 32oz. widemouth Nalgene bottle for several years with a Nalgene brand splash guard in its top. I recently bought a 48oz. wide mouth Nalgene and discovered that my splash guard did not fit the 48oz. so I went on the hunt for a splash guard that would fit.  When I came across the splash guard by Guyot Designs, I was very happy. This Splash Guard not only fits the 48oz. wide-mouth Nalgene, but due to its flexible silicone design, it also fits the 32oz. Nalgene as well as a variety of other wide-mouth bottles (I have not tested it in bottles other than Nalgene, but have seen them used in other brand bottles).

A nice replacement top for large mouth bottles. Provides a smaller drinking area which helps keep the fluid off your body when the ice shifts or you turn up the bottle too fast.

I've used Nalgene bottles for close to 20 years and periodically have to replace the tops due to dishwasher heater element mishaps or because the strap eventually wears out. I needed to replace a top recently and I saw this humangear top at one of our Army/Navy Surplus stores and decided to try it. I have been really pleased with it. The Nalgene bottles are already a bit heavy and this lid doesn't really add much more to it than the normal top. But, you get the major benefit of a top that's easier to drink from and you don't have to worry about the ice shifting and dumping a load of water over your face/neck/clothes.

Keeps your bite valve clean and sanitary. Potentially prevents you from getting sick on the trail (as I did) when you're far from the trailhead.

I was hiking the Northern Traverse in Glacier in September. On the fourth night, at Stoney Indian Lake, I became really sick with a bad case of gastroenteritis. When we arrived at camp, it started to get windy, cold, and wet. I and my two hiking partners set up camp, then walked over to the cooking area for dinner. Curiously, I had no appetite and had to force down a freeze-dried meal. It was late, rainy, and cold, so we turned in for the night. About two hours later, I was awakened by a wave of nausea.

A secure fitting lid with a hard plastic straw, designed for use with Yeti Rambler products. Be mindful to select the correct size for your Rambler.

This is a secure fitting lid and hard plastic straw designed for use with Yeti Rambler products. Available for the 20oz and 30oz Rambler, this lid is manufactured with the same high quality that I have come to expect from all Yeti products. The lid creates a firm seal around the inner rim of the Rambler and is snug enough to stay solidly in place in the event of spills. I have used this lid along with my 30oz Rambler during long 12-hour shifts and several camping excursions. The lid does not alter the effectiveness of the Yeti’s insulating properties, and is ideal for sipping both hot and cold beverages.

The Hydro Flask Bottle Brush is a well-made, sturdy bottle brush that I vigorously use on all my water bottles, including those that can't go in the dishwasher and the hard-to-clean, narrow mouth water bottles.

Conditions: I came across the Hydro Flask Bottle Brush about 10 months after I broke yet another cheap plastic brush. I needed something to quickly and effectively clean my water bottles, and it had to be long enough to clean even my big Hydro Flask 40oz Bottle. I’ve found nylon bristled brushes to work the best, but couldn’t find a durable one until now...Enter the Hydro Flask Bottle Brush. Hydro Flask Bottle Brush next to my big 40 oz. Hydro Flask Bottle.   Size:Nearly 15" long (38.1cm) Ergonomic handle that includes a hole for easy hanging.

I love them. First of all, I only store cold water inside Nalgene bottles, even if mine are BPA free. In summer season, I fill the bottles half way through and place em in freeze for two consecutive days at least. The harder the ice forms, the longer it gets.

The morning of my planned trek, I take the half way frozen bottles and fill up the rest, then place em in these insulated carriers. They are in my pack whole day under the searing sun. I occasionally take the bottles to sip the ice cold water, then again place em in the carriers. Believe me, the ice runs out only towards to the end of the day and the water is still amazingly cold after arriving home at night. When Nalgene first issued these carriers, I got two of them, they were (are still) rock solid, very well manufactured.

I have the insulated tube but not the bite valve cover. I do use this with a Camelbak bite valve and cover - so quite similar end result. This works with Camelbak, Outdoor Products as well as the Platypus hoser tubes - although they all take a little time to feed through the high friction material (water lubrication helps). I use this mainly for extreme heat (Arizona) summer hiking and backpacking though it seems designed primarily for winter. It works to keep my water cool for quite long periods and I'm sure it will similarly keep water from freezing - but I find it's just a little too thick and bulky...

The AquaClip is a clever gadget that I recommend for those using Platypus-style water bottles. While the Ultralightest may cringe at the added 11 grams, this hiker is please to have my water bottle accessible, without having to contort myself to reach the water bottle in my pack’s side pockets.

Preface: Five months ago, Brentbrook posted his review on the Aquaclip. That review focused on use with a disposable water bottle. I am not a fan of disposable bottles. So I asked in the comments section if these would fit a Platypus bottle. Brentbrook did not know at the time. A few days later, Aquaclip owner and inventor Brian Cizek sent me a message asking if he could send me some free samples. I was very clear to Brian that I would be unbiased in my review. If I did not like this product, my review would reflect that.
