  • My favorite handheld water bottle for running
Style: *NEW* 500ml - Insulated Thumb Loop
This soft flask is extremely light and comfortable to hold. The thumb loop works very well for me. It allows me to hold the bottle securely using almost no grip pressure, with no need to overtighten the velcro hand-strap. The thumb loop is a good size for me and did not cause any chafing or irritation, but it might not work for someone with very large hands. The bite valve has good flow and I didn't experience any leakage. This is a soft flask, so it collapses as you drink from it -- no sloshing. I did not notice any plasticky odor or taste. I can't comment on the effectiveness of the insulation, as all my runs since getting this have been in very cool temps, but I'll update this review after I've had a chance to use it in warmer weather. ... show more

  • Great way to carry water
I like the flask. Easy to hold and drink from on the run. No slosh. As others have said the tightening strap doesn’t stay tight but as shown by another buyer, I put Velcro on it and that worked really well…. UPDATE!!! After 4 months of use I really love this bottle. I’ve had no leaks and had it in two 1/2 marathons. Made another modification. There was a small sleeve/tube that slid up and down on the strap to guide the pull tab. It was made of thick plastic and had a rough joint that rubbed on the back of my admittedly bony hand. I cut it off and it is much more comfortable. Great product ... show more

  • Great handheld running bottle!
Style: *NEW* 500ml - Thumb Loop
I really like softflask water bottles for running and this one is great! It is easily collapsible after you finish drinking and can be stored in a waist belt or pack. Easy to clean and the quality has been excellent for how much I put these bottles through. The hand strap works pretty well. You can also put a buff or other headband around your hand with the bottle for extra security, if you need that for running. I’ve used these for many ultra marathons and highly recommend! ... show more

  • Not For All
The HydraPak SkyFlask IT 500ml is an insulated collapsible water bottle that offers portability and temperature retention. It is designed to be lightweight and convenient for outdoor activities such as hiking, camping, or traveling. One of the standout features of this bottle is its collapsible design, which allows you to easily compress and store it when not in use. This makes it great for saving space in your backpack or luggage. The 500ml capacity is decent enough to keep you hydrated during short trips or workouts. The insulation feature of the SkyFlask IT helps in keeping drinks cold for longer periods, ensuring that your water remains refreshing throughout the day. The bottle is also BPA free, so you don't have to worry about any harmful chemicals leaching into your drink. However, one drawback that some users have mentioned is a funky aftertaste. While the bottle itself is made from safe materials, some people have reported a plastic or rubber taste that lingers in the water, especially when it's left in the bottle for extended periods. It's important to note that not everyone experiences this issue, and it may vary from person to person. Despite the potential aftertaste, the HydraPak SkyFlask IT 500ml remains a solid choice for those seeking a lightweight, collapsible, and insulated water bottle. It offers convenience and functionality for outdoor enthusiasts and travelers. ... show more

  • Great flask
Style: *NEW* 500ml - Insulated Thumb Loop
This is my go-to flask for all runs now. It's easy to clean and durable, and a great size. The wide snap-top mouth makes it easy to refill. The insulation doesn't work very well, but I didn't expect it to in 90+ degree (F) weather. I'll almost certainly buy another one.

  • Functional but issues with insulation and strap
I've been using this bottle for a couple weeks now and the bottle definitely works for running. The collapsing feature is nice since it prevents the typical air pocket that causes the water to slosh that happens in hard bottles. It does take a bit of getting used to holding something mushy like this after having used hard bottles for years. Although I think this Skyflask functionally works I think there are two parts of the bottle that could be improved. Although the insulation is a nice feature to keep the liquid at temp for longer, I have a slight issue with how its constructed. There is an approximately 5 mm seam in the plastic shell running the length of the bottle under the hand strap where the insulation is compromised (see picture). If I put in water and ice, I can really feel the coldness in my palm which can become painful like holding anything really cold. I avoid putting ice in my other uninsulated hard bottles for this very reason, so I was hoping that this insulation would take care of that issue. I wish there was no seam or the makers at least put it on the other side where the fingers meet so I'm not touching the cold seam constantly. I assume they put it under the strap for design aesthetics. For this reason I don't put ice cold liquids, which is kind of disappointing. Secondly, I wish the strap had a way to get locked in place. Over the course of a run you want to cinch the strap down to keep a tight grip, but the strap will loosen itself over time. There isn't too much slack to begin with anyways so at its loosest I can still maintain an okay grip so its not too bad, just annoying to use. ... show more

Style: *NEW* 350ml - Thumb Loop
I never used to run with a water bottle, but I thought it was time. I love that the thumb hole on this one lets you relax your hand without fear of dropping the bottle. Being collapsible also makes it easier to hold and keeps it light. It's easy to fill and to clean. Make sure to give it a good rinse when you first get it. Mine tasted a little like vinyl for the first use or two, but then it went away. I didn't want anything large or heavy, but if I were to buy another one, I would probably get the 500 mL bottle for those really hot days. ... show more

  • Good for a short jog/run
Style: *NEW* 500ml - Thumb Loop
I have used this a couple of times and it doesn't leak. The strap attached to the bottle is adjustable and I am able to hold it effectively without any issues. I am so glad I bought this! The size is small enough to not feel like an annoyance while jogging. It also provides enough fluid get me through a short jogging session before hydrating at home. Clean up is easy, just had to wash it a couple of times to get rid of the "boxed plastic pool" smell. ... show more
