Only way to have a Nalgene

Every time I loose my Nalgene, I grab one of these too. It's made with quality plastic, and it's a useful little utility.

I got sick of having water dribble down the front of my shirt from my wide mouth Nalgene.  This fit the Silo perfectly, and not only gives me a smaller opening to drink from, but it's still wide enough to refill the bottle from if I'm too lazy to unscrew the whole thing.

Like it a lot. Will hold a full nalgene liter bottle plus. Maxpedition makes some tough gear... got to like that. The only downside is the lack of a strap, must be ordered seperatley.

Everyone should carry hydration with them.  Especially if you live in the desert areas during the summer.  This little bottle could be a life saver.  Work great with the BLACKHAWK! S.T.R.I.K.E. Utility Speed Clip Nalgene Bottle Pocket Pouch.

Great product.  The bottle is small, so I used the filter with my standard nalgen which allowed for more water.  You may have to cut the straw to use with Nalgene.  I went out and found the same size tubing so I can use with both bottles.

It does fit a Nalgene. I use 1 Nalgene that I carry around with me from work, on my bike, at the gym and this one gets the job done. It would be nice had they made it a little bit bigger to fit a Nalgene without me worrying about the metal breaking. I don't think it will but it still concerns me.

Bought two of  them for a Nalgene 1 liter bottle and Jetboil Flash. Nalgene fits perfectly, the Jetboil Flash is tight but it fits. Not enough room for the fuel as well in the pouch :(

It's very durable and great replacement to Nalgene caps that tends to leak after the long usage.  I have these for all my Nalgene bottles.  Easy to drink out of without dribbling on shirt through wide mouth bottles.

I purchased this bottle to fill a role previously filled by some traditional Nalgene bottles. It was convenient to switch to this bottle, as opposed to similar options from other vendors (like Klean Kanteen) because it was more or less a straight swap. Remove the old plastic Nalgene from the pouch and put this in it's place. No having to adjust cords, no worrying that the bottle was different dimensions and would fall out, or change decades of packing habits to account for a new size and shape bottle. As an added bonus - since this was actually designed as a Guyot product - my Guyot Gription fits perfectly, which is not the case with other wide mouth bottles of this size that I tried. I did not test it with other bottle accessories, but trust that other accessories built for traditional plastic Nalgenes will fit this one which is great if you've already spent money on those.

I did purchase a Klean Kanteen wide-mouth of a similar size as well for comparison. Both bottles are nice, but with the KK being slightly larger and not being able to use the Gription lid it's not as easy to swap into a routine as the Nalgene stainless product. I also found the Nalgene to be easier to drink with when drinking directly from the bottle, especially in the car. The transition on the Nalgene is sharper, and it also has a longer  and slightly narrower neck, than the KK product and to me that seems to reduce sloshing and make drinking more comfortable than the KK option. I also appreciate that the Nalgene has a tether to keep the cap and bottle together. This is great while using it and a "nice to have" while storing it.

The bottle has withstood drops without issue, it's not tippy, and it is easy to keep clean. All good things.

Just about the only downside to this bottle is that it's quite expensive which is actually a huge problem. Perhaps this is due to the bottle being discontinued and more difficult to obtain, thus commanding a premium (grab one while you can!) It costs significantly more than Klean Kanteens, which is not a big deal when you order one, but becomes a huge problem when you're trying to outfit yourself and others with multiple bottles. For the price of this bottle + shipping you can actually get two Klean Kanteen wide mouths. Based on what I've seen in using them both, while this bottle is slightly better than the KK offering, it's not twice as good, especially given that many companies are now advertising accessories that fit both Nalgene and Klean Kanteen offerings.

If you must have a bottle that is a stainless clone of your existing Nalgene - this is a great buy. However, if you're just looking for a wide-mouth bottle that you can take on the trail with you - consider your options.

It is the original Nalgene.  It is light, holds a lot of water, has a wide mouth and is guaranteed for life.  What else is there to say?  There are videos on the internet of people breaking them (most include freezing water in them). But if you don't purposely do that these are almost indestructible but if you do, the company will replace it.

Works really well, except its really heavy. I probably should have either gotten a smaller size, or a nalgene instead.

Top notch product. Never comes undone from my backpack (attached via included molle straps) and keeps my 32oz nalgene secure.

I love my Nalgene bottles. They're so tough, I have dropped them so many times and I don't remember having one break. Great bottles!

Nalgene has always been making quality products. Their sturdy design has always made me return to this brand. My only concern is the somewhat flimsy design with the lid connection. Otherwise, great for the value.

I have been a dedicated Nalgene owner for several years but sadly lost the one I previously owned. I ordered this one and am just as happy with my 1L bottle as I was before. These water bottles are so durable. I have taken them on hikes and adventures domestically and abroad and it has stayed reliable and intact. I am a forever Nalgene user. The 1L design is great because it also helps me keep track of my fluid intake throughout the day.

Exactly what I was looking for to replace my old plastic canteen. Fit my canteen cup and carrier exactly as expected. Expect nothing less from Nalgene

Great size for my wife who only has three discs. Like others said, it does not fit a full Nalgene but we us 32 oz hydro flask that fit fine.
