A Guyot Gription For My Nalgene Bottle
I've been using a big wide-mouth Nalgene bottle for probably about a decade. I often use it when camping with Scouts--it's not the best to hike with, but it's great for around camp. Quite a while ago I saw this thing called a Guyot Designs Gription when I was at EMS. I finally bought one a few months ago.
2005/09/25 Update: I wrote a review of the new model, which addresses several points I make below, and basically improves upon the model. If you want to buy a Gription, I recommend reading the Guyot Designs Gription Mark II Review.
The Gription is a replacement lid for wide-mouth Nalgene bottles. There's a handle to make the bottle easier to hold, and a hole in the handle for a carabiner or whatever to hook to your bag. (In the photo above, I have a carabiner through the hole.) Pressing the orange button opens the sipping valve so you can drink out of it. When closed, it seals as well as the regular lid. The valve works pretty well, though I wish its opening were a little larger. It also solves the problem of "splashback," which always happens with wide-mouth bottles. The whole thing comes apart for cleaning, too.
There's also a little silver locking slide button on the Gription. "Locking" the bottle prevents the orange button from being depressed, so the valve can't open and water doesn't leak out when you don't want it to. It's a good idea, however I think it's been poorly executed: mine's already broken (or atleast, it doesn't work well). Since it can be easily disassembled, I could see that the lock only has a tiny nub to lock against. The nubs on mine don't look to be worn down, it's just that they don't provide much resistance in the first place. Actually, I'm left wondering at the usefullness of the lock in the first place--the shape of the Gription offers some protection from accidental presses while the bottle's on its side.
Regardless of the lock's shortcomings, I think the Gription is a nice product for use around camp or wherever. (Of course, hiking with this thing adds quite a few unnecessary ounces!) I just have a little trouble paying more for a Gription than the Nalgene bottle it goes on!
