Terrible new design

This updated version is terrible. The lid is bigger, heavier and thicker than the previous model. During mid long runs ( 3h-5h ) the lid bruises the chest for being too big. The longer thinner bottle gets wobbly right after the first sip and the big lid makes it flapping out of the pocket. I am patching my previous one so I can still use it, this new model is a disaster.

Great Bottle

Love this bottle, used it for training during the summer months and found it so useful. Fits perfectly into the Salomon belt. Bought another for my son for his long runs.

I bought this to use when out in my wheelchair, fantastic bit of kit. Use every day, fits well in my waist bag, easy refilling and packs small when used.

Great for a trail race

My favorite bottles I have found so far. They work great and combined with the Salomon vests, they are easy to drink from while running. Bottles I have used in the past either leak or are difficult to drink from while moving. These flasks don't have either of those problems. Pros: 1. Easy to fill. I find these much easier to fill than other soft flasks I have used in the past. 2. Good rate of flow, easy to drink from while on the move. 3. Doesn't leak, the most important aspect of a soft flask. Cons: 1. Not insulated, doesn't keep water cool Overall I would recommend these bottles, you just have to make sure that you have a pocket in your vest long enough to fit them.

Nice vest system but the bottles leak

My girlfriend and I both love our Adv Skin 12 vests but 2 of the 4 bottles that came with them leak from the cap. This issue showed itself almost immediately. This is very annoying when it’s cold out or if you have a hydration drink in them. We have to take turns using ours now since we only have enough bottles for one vest.

Decent but awkward to use

The flasks are built well and easy to fill. I have the Solomon XT 15 pack and these are very difficult to insert into the front water pouches without spurting water everywhere. The spout/mouth piece is very sensitive; the slightest touch and water is going everywhere. One have to take extra care not to touch the nozzle.. I have not been able to buy straws for the flasks as they are currently unavailable and seem to be not really usable or at least difficult to use without one. They should come with the straw and cap as the nozzle is so sensitive to touch water leaks out easily inserting or carried any other way other than upright in front pouch. Recommended only with the additional purchase of straw and cap but then the price becomes quite high and availability is not good.

Perfect for my needs

I purchased this soft flask for my running belt. It fits into my pouch and doesn’t leak. The wide cover let’s me refill it easily and the specially designed nozzle allows for easy fluid intake. It shrinks with the reduction of fluid as well so there are no air pockets in the flask. Overall I am very happy with my purchase.
