After running out of water last year on my Colorado elk hunt I found the Grayl a perfect and essential piece of kit. Sure enough both my guide and I ran out of water in our camel backs while chasing elk thru the Uncompahgre National Forest last week. Thanks to this piece of gear we were able to replenish our packs with fresh cold mountain stream water safely and effectively. I ended up killing my first elk with a bow this trip and the Grayl was literally a lifesaver and kept us in the field instead of having to return to camp when water ran scarce. It will be with me for every backpacking and hunting trip from here on out. Thank you for a great product!
This is a super versatile system that has saved tons of space and weight in my bag. It preformed really well on a recent trip, the water came out perfect and the cup portion worked well for heating liquids. In my opinion this system is worth the money in the weight savings, water quality and versatility that it provides. I have other grayle water purifiers and they're great, although this one is my favorite and I use the cup portion even when I'm at home. The titanium heats up quickly with the burner but due to its nature it also cools down to room temp rather quickly and vise versa.
I've had it for a few weeks, and use it almost everyday to filter my water from the tap. I noticed that the inner water container is getting gouged each time I press it to filter. I've tried to make I don't let it lean to side and I press, but it isn't always possible to avoid it scrapping the lip of the outer container. Feeling the side of it, I can feel slivers of titanium in the gouges; this makes me worry about ingesting slivers of titanium. I know they will be in caught by the filter, but if I actually use this to heat water (I haven't yet); then those fragments of titanium will be in the outer container when I add water to it.
I was super stoked when Grayl announced this product and immediately pre-ordered one. Though timelines were tight I had an Algonquin backcountry trip planned and was looking forward to putting the Geopress ti through it's paces. However, when I received the item there was considerable scratching on the inner container and cup (which happens after use, but brand new is a bit of a bummer). I opted to take my Sawyer Squeeze with my CNOC bag and Snow Peak pot just in case giardiasis or any other nasty stuff which is prevalent this time of year in the water. Will test it closer to home to make sure the scratches dosen't create little havens for bacteria when using the cup for cooking.
This thing was incredible, used on an overnight trip. I wanted to test it out since I plan to use on my week long backcountry hunt. It worked out so well, the titanium sleeve/cup was great, I didn’t have to pack an additional pot to heat my water in. The ease of use was so simplistic great equipment and the construction is well built.
I haven't had the opportunity to use this Grayl Titanium Geopress and lid. However, I have discovered that it nests well with my 750ml Titanium mug that also has a lid. I put the mug lid in the bottom of the mugs bag with the mug on top of it. I can then put the Grayl Titanium lid inside the mug with the Grayl Titanium Geopress nesting in the mug. I am excited about using this system during hunting season here in Montana this coming fall. It is a great addition for my travel Survival kit as well! The Grayl Titanium Geopress w/ lid, in my opinion, is an outfreakingstanding piece of kit!!
The material is awesome, my adventure is my job, I’m a lineman for my local power company and I always have this piece of gear with me all the time during storms. It’s been a real life saver 👍🏿👍🏿💯💯❤️❤️ it’s also my emergency and survival kit!!
Quick and easy review, so I go on overnight adventure riding to different areas around sequoia national forrest. There is 100’s of streams, creeks, and rivers. For those of you that familiar, I took a drink out of fish creek, snake creek, and south fork kern river yesterday (risking an upset stomach) this GRAYL titanium did not disappoint. I boiled filtered water to make a quick dinner and feel like I put this to the test with the drops and the oops and the oh damns. My GRAYL still kept on filtering water. It’s a part of my critical gear now and yes I recommend this adventure riding, hiking, surviving in general and even for hikers doing the PCT.
This filter is perfect. I’ve used Grayls around the world… Ethiopia, Colombia, Peru, Nepal, Nicaragua, Mexico… I’ve used them with all types of water, always questionable at best, and never gotten sick… and now with the additional ability to heat water and cook in it, this is the ultimate. I’ve always loved the ability to simply scoop and plunge for clean water. It’s easy. And more importantly, reliable. But now with the ability to mix in a Scratch or even an instant coffee… amazing. And the titanium for heating water and cooking is amazing. Put the lid on, use a small burner, and water is boiling FAST. SO stoked about this. And built to last a lifetime.
In my goal to go ever lighter, the GRAYL GeoPress Ti seemed like a great item. I could combine my water purification system with a lightweight cooking vessel to boil water, and also use it as my trail water bottle that I could easily replenish at each stream or pond that I crossed on the trail. Instead of carrying a water purification system, a boiling kettle, and a trail water bottle, I could replace them all with this single item. In many ways it worked very well on a recent weekend backpack trip into the Cascades. It was indeed robust and lightweight. It worked well as a vessel to boil water for my coffee and freeze-dried poison. It fit easily and well within my lightweight backpack. It was easy to fill at any stream or pond. As I mentioned, it was perfect in all ways except one: ease of use!!! When you scoop some water into the lower cylinder and insert that filtration cylinder into it, it really takes a lot of exerted pressure to filter the water. It does help to twist the inner cylinder while pressing down, but I really don't know how anyone who weighs less than about 180 lbs could exert enough downward pressure to filter the water! I weigh a little over 100 kg, and it took all of my weight pressing down on a rock surface to filter the water.
