The Hydrapak SF500 Soft Flask is a hybrid bladder and sports bottle. While everyone from hikers, joggers, bikers and gym goers seem to use standard water bottles in different shapes and colors, they all mostly suffer from the same problem. The materials, and the rigid shape that limits how you carry or travel with your hydration.

The SF500 differs from other water bottles because of its soft wall construction that expands like a bladder when filled, but can be collapsed and condensed like crushing a soda can. This makes it so when empty, the soft flask can be easily stowed in a pocket or bag. It's flexible nature also lends itself to runners or other athletes that only have pockets on their tight fitting performance clothing, as the bottles softness makes it more comfortable if carrying close to the body. The 500ml volume and easy refill-ability make it a nice companion on long outings.

The valve system on the SF500 is quite good, the bite valve is easy to use and expels water nicely. The valve can be closed off when in storage to prevent any unwanted leaking, and the dust cover cap is tethered to the neck for retension. The nipple is slightly scalloped to provide resistance to the dust cover's inner ridges, so that the cap is held firmly with friction, and the valve lock can be rotated without removing the cap. There are also multiple lashing options if you wish to secure it to the wrist or other equipment.

I see the SF500 being most beneficial to athletes or active individuals who travel long distances away from their vehicle or facilities. Without a flat base to stand the bottle vertically I don't see this soft flask being advantageous in a gym setting, but rather in a bicycle's bottle holster or on your person either in a pocket or bag/pack. The ability to squeeze it flat when empty makes it easy to carry more than one, so I would recommend getting 2 bottles, especially for those 'death marches' where 1000ml of water is a must and storage availability is sparse.

"As you drink from the SoftFlask, it collapses on itself like all bladders do.  This eliminates all sloshing and allows you to stow the empty SoftFlask easily, in  my opinion, a huge improvement over other handhelds." - iRunfar.com
