Bought it for Christmas for my father, mostly to see if I liked it so I could buy myself one as well. We tried it on several different brands and styles of bottles and it leaked on all of them. Definitely wouldn't trust it in a pack. They did refund the price of the purchase, but were pretty snarky about it in the process. It's a good idea, but just didn't work.

This product makes a huge positive impact to my backpacking - I can now take periodic sips of water on the move without having to carry a water bottle in my hand or on my pack straps. Fits a smart water bottle perfectly and hose is plenty long to reach either side pocket or even rear pouch. Air hole has a small relief valve in it to prevent water from spilling out and to keep foreign material out of your water. The hose disconnect allows you to change out the cap and straw from your empty bottle to your full bottle. The clip to connect hose and bite valve to pack strap is helpful but kind of flimsy and prone to falling off my pack strap - would like to see that proved. Only reason I give this 4 stars. Product is well made and rugged. I would recommend this for anyone who has trouble reaching the bottles in your pack pockets without having to take off the pack.

Ordered this for my Mt. Zion trip and it worked awesome. The only issue I had was the little white plug fell off along the trail leaving and open hole. I messaged the company in hopes of a replacement plug but we'll see what happens. Other than that, great product 👌

My son who is a backcountry ranger showed me this product and I couldn’t wait get one!! I HATE bladders!!! I love this product because I can see how much I’ve drank, easy to clean, stay hydrated easier!! Thank you!!!

Used this while hiking and thouroughly enjoy getting to drink while walking. However, the small air valve fell out pretty soon after starting use and since then I got water on me everytime I bent over. Fixed it with some glue but not happy with the way it went

This is THE BEST hydration system I’ve ever used. It works SO WELL! I have been unintentionally dehydrating myself on hikes bc I’m too lazy to take my pack off to get a drink and I HATE water bladders. 😂

I’ve been using the Hard Side Hydration Swig Rig system for approx 3 years and found it to be the best water carry system around. Very easy to refill and clean the bottle as compared to a water bladder. I can always see how much water I have too. I use it for backpacking & hunting and vary the water bottle size depending on how far I’m hiking or hunting. They also have a great customer service department and are very responsive. Can’t ask for much it’s more than that!

I've done two Camino de Santiago routes and use Smart Water bottles to save some weight. I use them at home in WA mountains, because. This is exactly what I needed, but didn't know I needed it before I saw it. On the down side, I drink a lot more water now, which means more filtering. But staying hydrated is great.

I like the convenience of the hydration pack straw/valve but hate the hydration bladder because of leaks and gross flavor. This product solves this problem. Now I can take drink water without struggling to grab/reholster my water bottle and I don’t have to deal hydration bladders. Highly recommend!

Great product!

Awsome product fits perfectly in my Kuiu bag when I ride my bike. I bought both wide and small bottles. Thank you
