I have been wanting an alternate for my bladder for years and this is perfect! I took this on a two night backpacking trip and I loved it so much, can't wait to use it on all of my future adventures. I have been recommending it to literally everyone; my roommate already ordered hers and my brother wants to order one, too! Seriously, cannot recommend enough. So easy to refill, love that you can take off the straw and still use the nalgene as a water bottle, and makes it so I can monitor my water intake much easier!

Hey this swig rig worked so well! It fitted to my tall Nalgene perfectly and eliminated the need for a bladder. The bladders are cumbersome and sometimes leak, having a hard Nalgene double as a bladder with the swig rig attachment saved weight and improved efficiency greatly. I finished the JMT with this and wish I had made the switch to the swig rig earlier. Highly recommended! The orange tube in the photos is connected the my Nalgene and very durable.

First time trying out this product and it did not disappoint! We opted for the insulated tubing which kept our equipment from freezing at 21 degrees, used the insulated covers for our nalgenes, and the spoon covers (which seem small but make a big difference in keeping your spoons away from touching stuff in your bear canister). We used it while Hiking Mt. Whitney and many people had tubing freeze so I can't recommend the insulated enough if you will be in colder climates. We used Bladders prior to this for backpacking and won't be going back. It's so easy to access and also gives you more versatility with what you can do with your nalgene. We were able to use it easily on both our 65 liter packs and our smaller 16 liter packs. The only small upgrades that could make this product even better would be a magnetic clip for the tubing. We ended up not using the plastic clip that comes with it at all because it wasn't easy to use and didn't stay securely on our straps. The cap that covers the mouthpiece was pretty loose and didn't always stay on the mouthpiece, so that fit could be a bit tighter. The water flow is good but you can't get a solid gulp without really working hard at it, which helps you from over drinking but not great if you're super thirsty. Would be great if it flowed a bit easier. That being said I would still buy this product again and recommend it to friends and backpackers. Those upgrades don't make or break the use of the product.

The last time I went to Mount Everest Basecamp, it was a pain to get to my water bottle for a drink. Because I’m going again, I wanted something that would work for my backpack and get the hydration that I need. This has been a great product and has performed above my expectations! I highly recommend it for those using Nalgene bottles, that are hard to get to and their backpack. It was a great buy!

Works perfectly with my Nalgene. I prefer using a Nalgene over a hydration reservoir, especially when filtering water into it on longer trips—it’s so much more convenient. Recently took it on a multi-day packrafting trip and it performed flawlessly.

Although this product is still extremely new to me, it worked great upon the first trial run (using 48oz Nalgene). Takes all of 4 seconds to attach it to your water bottle from the time you open the package - seems like an absolute backcountry game changer. I’ll be sporting it in the Middle East desert and believe if it can survive out there, it will survive anywhere.

Easy set up, and works just as well as a soft reservoir, without the worry of leaks or kinks. Simple to convert your nalgene back and forth. Customer service was also super responsive to questions. Hose is comfortably long when carrying bottle in side pocket of backpack.

I love a company who stands behind their product, and that’s what Hardside does. The quality is evident as soon as I got my hands on it. Hydration is key whether you are hiking, hunting, biking, etc. and Hardside hit a home run! Every outdoorsman should have hard side in their toolkit. I’ll be recommending this to my friends and family!

Love the design and versatility Works great and I don’t have to worry about a bag puncture again. Truly a game changer in the field. Quality is absolutely amazing. Customer service is the best I have ever seen in a company providing a product.

The Swig Rig adaptation system offers the perfect compliment to my favorite hydration bottles. Easy and accessible when added to the external pocket of my pack system. Easy to use and maintain, and very easy to recommend!

Really simple and elegant way to turn a nalgene into a hydration reservoir. I actually cant believe I had to look so hard to find something like this. Always seemed redundant to run a bladder and bottles, or have to choose between the two. Also this is great for biking as you can just run the hose up from the bottle cage (assuming you have a liter cage)

I go on multiple canoe trips in the BWCA every year, and I've always had issues keeping hydrated. With this product, I can simply clip the reinforced lid onto my belt or bag and suck away! Portages are a breeze now that I can hang this over my shoulder and drink water whilst carrying a canoe.

Admittedly I was reluctant to give up my water bladder, but when my bladder popped on a rock during a Wyoming elk hunt, I was forced to convert to the Mountainscape Nalgene (gift from a friend). I spent 5 days in the backcountry with this hydration system and another 1 liter Nalgene I used for my afternoon drink mix. This combo provides the perfect amount of water for a full day hunt in the mountains, including packing an elk out of rough terrain. The bottle fits well in my backpack hydration pouch and the hose is of sufficient length. Filling it is much easier than filling a bladder if you are pumping water from a stream. Also, the durability over a soft bladder cannot be overstated. My friend kept his in is backpack side pocket and it never came out of the pocket or was in his way. Great product!

I am so happy I found this product. My favorite part is how easy it is to clean and dry out. I like having a bottle when I am not on the trail and the ability to drink without removing the bottle when I am. It is truly the best of both worlds and I am absolutely in love with it.
