|---|---|---|---|---|
 | Budget | About 6 oz empty | Camp water you can put in a bear can | Heavy when full, and it is only a bottle |
 | Budget mid | About 3 oz | Camp water storage | Not a filter |
 | Budget mid | About 2.4 oz | Dirty-water storage for a Sawyer-style filter | Not a treatment by itself |
 | Budget | Light | Everyday backcountry bacteria and protozoa | Does not remove viruses. Clogs in silt. Can freeze. |

The picks
Indestructible bottle
Nalgene Wide Mouth 1L
A Nalgene is a poor choice as your only long-trail bottle because a full liter of plastic is heavier than a smartwater-style bottle. It is a great camp bottle and a great bottle for kids who drop things. Do not treat the bottle as a filter.
Who should buy it. Car campers, kids, and anyone who wants one bombproof bottle.
Pros
- Durable
- Wide mouth
- Hot water tolerant
Cons
- Heavy
- Narrow mouth versions are worse to clean, wide is the one to buy

Soft flask for storage
HydraPak Seeker 2L
Use it as storage after treatment, or as a dirty reservoir only if you are disciplined about which cap is which. A soft bottle in a pack needs a little care so it does not burst on a sharp edge. Two liters is a useful camp size for one person.
Who should buy it. Backpackers who cache water at camp.
Pros
- Light
- Packable
- Useful volume
Cons
- Can puncture
- Easy to confuse dirty and clean

Dirty-water bag
CNOC Vecto or Vesper bag
This is a plumbing piece. It does not make water safe. Label the dirty bag so nobody drinks from it. Rinse it. A 2-liter bag is a fair solo size. Groups want a bigger bag or they wait in line.
Who should buy it. Sawyer and similar squeeze-filter users.
Pros
- Light
- Pairs with squeeze filters
- Rolls small
Cons
- Not a filter
- Can be awkward to fill in shallow water

Best default filter
Sawyer Squeeze
Squeeze it from a dirty bag into a clean bottle. Backflush it. Do not let it freeze. It does not handle viruses, so it is the wrong only-tool for some international travel. In typical North American mountain water it is the default for a reason: light, cheap, and field-proven if you maintain it.
Who should buy it. Backpackers filtering lakes and streams at home.
Pros
- Light
- Inexpensive
- Threads on common bottles
Cons
- Slow when clogged
- Not a virus barrier
- Freeze damage

If you only buy one
Pair a Sawyer Squeeze with a CNOC dirty bag and drink from a lighter clean bottle. Keep the Nalgene if you want one bottle that can take a beating or hot water.
FAQ
How much water?
Enough to reach the next source with a margin. In dry country that can be liters, not sips.
Can I drink from the dirty bag?
No. Label it. Treat first.
Is a hydration bladder better?
It is convenient and it is harder to know how much is left. A bottle is simpler to manage.
