Can anyone tell me what the tensile breaking strength of this rope is?
Will 50m length be in stock anytime soon? I only need 50m.
I had a Sweetwater Microfilter for backpacking for years and then needed to buy a camp-size filter for our summer camps and found this one. It's GREAT! I've had it for more than 2 years and no problems. The crazy thing is, that it's only about 1 oz. more than my backpacking filter, but requires no effort, is a lot faster, and can filter 4 liters of water in no time flat (and no standing over a small stream sweating and pumping!).
I like Jeff's suggestion below to remove the clean water bag entirely and to shorten the output tube - it saves weight and works well. Unlike my Sweetwater, this baby hasn't ever clogged and my favorite part is that it's totally hands-free - no pumping ever! I really like the valve system which you can close/open with a thumb to turn off/on the water flow on the clean side. I always hang the "dirty" bag on a tree (like in Jeff's pictures) and then just use the valve to control the water flow.
Originally, I was concerned about the plastic holding up, but after 2 years of heavy use in varied environments, I find that it's a lot tougher than it looks in the pictures. I've had no leaks, rips, or any problems despite some extreme conditions... I also like that the bags are clear, allowing you to see the water inside, rather than the opaque bag of the MSR Autoflow Gravity filter. I just prefer to see any potential problems rather than wonder why something is going wrong!
As for effectiveness, I do not live in the US or Western Europe and have never gotten sick from this filter. One of my friends from the UK actually asked if she could filter our in-country bottled spring water through it b/c the Platypus filtered water tasted so much better!
If you're looking for a light-weight, easy-to-use, effortless, long-lasting filter with a life-time warranty - this is a really sweet deal!
I do not live in the US or Western Europe and I've never used a secondary purification system and haven't gotten sick from this filter. If you're really worried, just buy a viral-guard cartridge and add it to the hose as another in-line filter.
I don't have experience with the MSR filter mentioned, but have used the Platypus filter for more than 2 years now and really like it.
I never bother to close the "dirty" bag, since I just hang it up on a tree branch. It is difficult to close the clean bag, but as mentioned in other reviews, pressing it against a hard surface (like a tree trunk) or using both hands opposing each other and working it closed by pinching rather than sliding works. And if you hang the "clean" bag on a tree lower than the "dirty" bag, then you don't really need to close it either (or you can just have the water flow into another container or directly into drinking bottles if desired). After filtering, I detach the "dirty" bag + filter, hang it on the lower limb and hang the "clean" bag from the higher limb after closing off the valve.
I haven't had the need for a pre-filter, so I'm not sure if that would be helpful or just clog up faster (my other backpacking filters with prefilters tended just to clog quickly and using a coffee filter over the intake was much a better solution to preserving the filter life). The platypus filter is easily back-flushed, by reversing the direction of the flow/bags, so I don't think clogging is really much of an issue.
Personally, I find this filter a lot easier to use than a traditional hand-pump backpacking style filter. Not only that, but it filters a LOT of water in a very fast time. I really like the control valve on the clean hose, which allows it to be easily used to fill bottles (or mouths) directly from the clean back with no spills.
It's really a super filter at a good price!
You don't need to waste money to buy a BA sleeping bag with a sleeve. This pad works great with any mummy bag. As for sliding off, I've never had that happen, despite sleeping on inclines and not having a special sleeping bag... If you're that worried about it, just stick a few velcro dots onto your bag and the pad or stick your pack on the downhill side.
I used a few basic foam pads, a Ridge-rest, and then several different self-inflating Therm-a-rests for years of backpacking and camping, and never had a comfortable nights' sleep on any of them (call me the Princess and the Pea).
So, about 7-8 years ago, I bought the BA Air Core Sleeping Pad - Mummy and find it to be the most comfortable pad I've ever tried (I haven't tried the Term-a-rest Neolite yet). It's held up well to all kinds of abuse over the years I've owned it.
I'm 5'8" 145-150 lbs, and as a side sleeper, I find it to be very, very comfortable. The key is to fully inflate it, then lie on it and deflate it a little until it feels just right. Fully inflated is too firm for me, but let some air out and it's more comfortable than my regular mattress. It's also roomy enough that I never feel like I'm falling off (but that could be from years of practice sleeping in high hanging bunk-beds where a fall would be fatal and one must know exactly where one's body is in relation to the bed at all times).
It does take some time to blow up (but less than a pool mattress - I've tried those too, but this is far more comfortable, packs a lot smaller, and is way more durable). And even on cold nights, I never had it deflate.
As for packed size, I can fit it *into* a Nalgene bottle, no problem. I fold it into 4ths lengthwise before rolling it... So, I think the key to making it small is knowing how to fold/roll it - experiment to find what works best for you.
This summer, it developed a slow leak at my last camp and I had to re-inflate it in the middle of each night. :( Hopefully, I can find the leak and patch it - if not, it's supposed to have a life-time warranty! My guess is that it may be from storage (I leave it loosely rolled up in its stuff sack) or just old age... But that said, it's lasted longer than my best light-weight Therm-a-rest (which popped from a cinder and wasn't repairable).
As for the cold, it definitely does NOT insulate well. But that makes sense - it's an AIR mattress for crying out loud! It doesn't have any kind of coating to reflect body heat back or keep out ground temps. The solution for me is to either use a space blanket or a cheap foam pad under it for fall/winter camping (which also help to keep it from sliding around on the ground).
A weight-saving option would be the BA Clearview Air Pad - Mummy (http://www.backcountry.com/outdoorgear/Big-Agnes-Clearview-Air-Pad-Mummy/BAG0129M.html), but the polyurethane is probably not as durable as the 70 denier nylon laminate of the BA Air Core Sleeping Pad - Mummy.
Overall, I think it's the best bang for the buck for a comfortable sleeping pad (and lighter than most at less than 19 oz. for the regular size).
If you don't want to shell out 3xs the moolah for the Therm-a-rest Neolite and can spare the extra 5 oz. or are worried about the durability of the BA Clearview Air Pad, then this is a super sleeping pad to buy - your aching back will thank you!
I've had this harness for about 5 years and use it mostly for rapelling and ropes courses in youth camps. It is not very comfortable for long periods of time (e.g., on belay) because it isn't padded. I also find that it is difficult to get the waist tight enough when using it in groups on multiple people b/c it doesn't use a traditional buckle system (it's backwards). However, that said it's a good all-around group harness and is fully adjustable. One thing that is really great is the belay loop - it's not dependant on the user's rise (which is a problem in groups with tall or heavier people).
I've used this harness for about 8 years, for everything from search & rescue to rapelling to climbing to ropes courses. It is really adjustable and I use it for groups and it fits most people (from youth to larger adults). The only downside is lack of padding (so it is not super-comfortable for long use) and the rise not being adjustable (which means group use is more limited). However, it is durable, simple to use, and light-weight. If you're looking for a no-frills, easily adjustable harness, this is a great one!
