## Description

Lighten your load and drink right from the source. We took our go-to flask and added filtration to create a system that delivers hydration without contamination. The filter — light and compact — screws on top so you can drink right from the flask. Or — if you’re carrying more water — use the system to fill a bottle or reservoir. Care: Avoid freezing filter. Freezing may ruin the hollow fiber membrane. If in freezing conditions we recommend you keep the filter in your pocket or near your body to prevent freezing. *Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42. Included in the package: - UltraFlask+ 500ml Flask - 42MM Filter Flask Cap - Bite Valve - BackFlush Adapter - Filter Manual - Basic Care & Use Instructions Specifications: - Capacity: 500 mL / 17 fl oz - Weight: 65 g / 2.3 oz - Dimensions: 240 mm x 70 mm / 9.4 in x 2.8 in - Material:TPU, Silicone POM, Hollow Fiber, ABS

Review: Ultralight perfection. - Just got back from a 9 day backcountry hike and i really loved having this. Glad I got this last minute. It spared me from having to use my normal gravity filter setup which does work great and is reliable but this is half the weight, a third of the bulk, much faster, easier and clutter free. It worked the whole time, not a glitch to be found. I think these types of flter do slow down and need maintenance to keep them going well but with my constant use for all those days I noticed it stayed flowing very well. I usually use an inline carbon filter but here I used just this and the taste was great. Of course, it was Adirondack water, but it did filter most of the tannens and I didn't get sick from all the beaver activity in the vicinity. So taste was great and I didnt notice any plastic taste at any time by the way. I liked that this could stand up on its own like a bottle if I wanted and it fit into my rather small backpack strap stretch mesh. I could just drink straight from it but i preferred just taking it out and putting it back in when done and it had just the right rigidity to push right in but still be flexible when needed. Another great creature was the little bite nozzle pulled off so that I could squeeze water into another bottle which I used for shaking up a coffee or electrolyte drink. The nozzle fits right back on and doesn't come off unintentionally. To drink is easy and just a bit of pressure gives water. Most of the water in the bottle squeezes out so there's not a whole bunch of wasted space and doesn't need too many dips to get the amount of water needed. I'd say about 2 of these full would squeeze out around 20 ounces. If you're ultralight hiking like I was, I highly recommend you spend the extra couple of bucks on this one because for that slight bit more you get perfection.
Review: Water filter - It works but is difficult to use.
