      The Hydrapak SoftFlask 500 is a great bottle that is designed more for minimalist runners and those who are planning on doing a lot of long distance running. This is often used in place of the standard hard water bottles that runners will use. It is so much more convenient to be able to roll the flask up and throw it in your bag, vest, or pocket when you are done with it. You can drink up and then forget about it. This bottle is great because even though the top and bottom are made out of a harder and more rigid plastic, the sides are made out of a lightweight rubber so you can crush the bottle down when are you are done with it, allowing you stash it away.

      This comes with a nice hand strap, mixed with the soft plastic, lets you grip it easily and comfortably while you are on the go. This bottle will fit easily in most of the hydration vests, belts, or pockets of a pack with no problem, making it easier to carry with you while it is still full. Since it is made from soft materials it can squish into almost any pocket with ease. It is also going to shrink down as you are drinking, making the bottle smaller and smaller, eliminating water movement while you are on the go.

      If you are looking for a great way to stay hydrated without having to worry about your contribution to plastic waste then this might be the right product for you. Many runners do not like to have to carry too much extra weight on their backs and prefer to not wear bladders so this a good option. You get the ability to stay hydrated without the waste and you can stash the bottle anywhere on you when you are done.
      Breathability is non-existent when it comes to this water bottle. After all, you do not want air to be able to flow into the bottle because that would mean that water would flow out.

      Making sure that you have a water bottle that is not going to leak is always a good thing. You do not want to have to worry about getting soaked through from your water while you are on the go, chances are that your sweat will soak through your clothes enough as it is. You also do not want to go for that drink only to find out that you are out of water because it spilled everywhere while you were running. These are not things that you are going to have to worry about with the Hydrapak SoftFlask 500 bottle. It has a leakproof auto shut off valve with a twist locking cap. The bottle also uses a bite valve which allows for a decent amount of water to come out when you are drinking. These features work together to ensure your water stays were it is supposed to, in your bottle or in your mouth. It also has a 42mm opening under the twist cap to ensure you have an easier time filling it up before you head out. Customers were very pleased with the fact that they did not leak at all and stayed sealed up very tight.
      The Hydrapak SoftFlask 500 water bottle makes use of a lightweight and soft plastic material that is collapsible to help ensure you can stay as comfortable as you can when you are hitting the road. The bottle itself only weighs 51g (1.8 ounces), of course, it is going to weigh a bit more once you add the water. It is not going to weigh you down too much while you are out. The soft plastic materials that make up the bottle squish down easily and mild to almost any space so you can carry wherever is most comfortable for you. It is going to fit in most of your standard packs. Whether you prefer wearing a belt, vest, or other packs the bottle will most likely fit into one of the pockets. As you drink up the bottle shrinks, getting smaller and smaller so you do not have to be burdened with the feel and sound of your water sloshing around with each step you take. Once your bottle is empty you can just squish it and forget it. No hassle.

      Holding the bottle is even comfortable. The soft materials conform to the shape of your hand helping you keep a decent grip on the bottle. It also has a convenient webbing handle that you can use to carry it comfortably if you choose to not put it in a pack while you are running.
      The Hydrapak SoftFlask 500 water bottle is about the size of a standard water bottle. It can hold 500 ml (17 fl oz) of water. The bottle, when empty, weighs in at 51g (1.8 oz) so it is lightweight. The actual size of the bottle varies. HydraPak states that the dimensions of the flask measure in at 200mm (7.8 in) by 80mm (3.1in), but that is when it is fully expanded. Keep in mind that this bottle can change its shape to fit almost anywhere, and it will shrink down as you drink, becoming smaller and smaller until you can completely crush it down.

      Many customers stated that this is the perfect size bottle for them, however, HydraPak does have these available in a smaller and larger size if you need something a little different. Some customers mentioned that the 500 ml one though was the perfect size for them. One reviewer stated that is a great size for those who are running up to a half marathon, suggesting that anything longer than that might require two bottles or the larger one.
      Durability is important. Many people prefer to purchase a reusable water bottle like this so they can help reduce their plastic waste, as well as save some money in the long run so they do not have to keep buying bottles of water. If your reusable water bottle is not durable you are still going to have to throw the plastic away, adding to your waste, and you are going to have to spend your money replacing it so you are not really saving too much. That being said, you are not going to have to worry about any of that with the Hydrapak SoftFlask 500 water bottle. It was designed for the long haul and is going to last you quite a while.

      You might expect that this bottle would not be able to stand up to the hardcore conditions that come with long distance running but they can. It may be soft and squishy but the soft TPU (Thermoplastic Polyurethane) is made to withstand even the most abrasive conditions, meaning that it will not tear open or break very easily, ensuring that it is going to last you a long time. The seams of the bottle are bonded together using RF welding which is a form of bonding the materials using electromagnetic energy instead of applying heat. The advantage of using this method for the seals is that it can, and will, provide a more reliable and consistent airtight seal to ensure the bottle will not break at the seams and will not leak.

      As an added bonus, this bottle is dishwasher safe although it is suggested that you keep it on the top rack of the dishwasher to ensure it does not get damaged by the heat of the water. The bottle will be able to handle heat up to 60 degrees Celsius (140 degrees Fahrenheit). On the other side of that, this bottle is able to be frozen safely, some customers like to freeze water inside of it so they will have cold water as it melts.
      The Hydrapak SoftFlask 500 water bottle does not come with any accessories, in fact, it is an accessory. Many customers will use this in conjunction with their other running gear as their way to keep themselves hydrated while they are on their runs.

      The soft and form-fitting plastic materials that make up this bottle makes it the perfect addition to your running gear. It will conform to fit almost anywhere so you can use this bottle with the gear you already have. You like to wear a running vest or a hydration belt? No problems, this will fit right into the pockets. Prefer not wearing any kind of back and just want to hold the bottle? No problem at all. The soft materials and hand strap work together to make sure you can grip the bottle comfortably and easily. No matter how you choose to stay hydrated and no matter type of pack you choose to wear, the Hydrapak SoftFlask 500 water bottle would be a welcome addition to your future runs.
      The Hydrapak SoftFlask 500 bottle has a very simple style and design. The only color it comes in is blue, but that does not seem to stop customers from loving it. The great design keeps customers happy and coming back for more.
