A water bottle is a pretty simple thing on the surface.
Source: bought it new
Price Paid: Can't recall, but probably less than $5.00.
A water bottle is a pretty simple thing on the surface. A container for holding water, right? But it's the fine points of design that make the Hunersdorff High Altitude Water Bottle my choice for everything. I've had one for over twenty years and though it will likely die soon, I am glad these are still made, and still readily available. Compared to all the others out there, these are simply THE choice of many high mountain guides and expeditions where gear must be functional and durable.
- Ribs on cap make it easy to open with gloved hands
- Wide mouth for adding snow or water
- Large square section threads prevent a frozen on cap
- BPA free
- Slightly flexible polyethylene will stay flexible in extreme temperatures
- Can be used for cold or hot liquids
- Cap is the same PE as bottle and won't crack
- Cap is not attached to bottle, so can be lost when removed from bottle
- Only available through suppliers that specialize in High Altitude climbing gear
- Because of the wide mouth, can be difficult to take a small sip from without spilling
- Threads and mouth size prevent the use of any standard screw on water filter attachments
Capacity: These are available in both 1 liter and 1.5 liter sizes.
Ease of use: Very easy to fill due to the wide mouth. The cap, because of large ribs, can be unscrewed using gloves or mittens. Large threads prevent having a cap that freezes on.
Features: As noted above, the ribs on the cap and the wide mouth make the bottle easy to use with or without gloves or mittens.
Construction and Durability: Made with a special BPA-free polyethylene that is formulated to stay flexible in extremely cold temperatures, helps make the bottle and the cap less subject to cracking as other plastic bottles.
Conditions: I purchased mine when REI had a small batch of these back in the mid or late 1980's. I have not used one above 14,000 feet, or in temperatures much below 0 degrees Fahrenheit. I have dropped it a number of times, and it now has some small surface cuts. I have noticed that the material is starting to become less flexible, so I suspect it is nearing the end of its useful life.
Availability: Usually just available from small shops that specialize in high altitude or cold weather expeditions. One source is Bradley Alpinist: http://www.bradleyalpinist.com/cart/index.php?main_page=product_info&products_id=211
