Backpacking Background:

I’ve been backpacking for nearly 25 years, and have slowly started developing my ideal style. I’ve gotten my pack weight down to roughly 20 - 25 lbs (9.1 - 11.3 kg) before water, and am whittling it down every hike. Day hiking is nice, but getting out over multiple nights is really what I enjoy. I like to take my time and view the scenery as opposed to hiking hard. I also like being comfortable and insist on an air mattress. I usually tent or hammock, but stay in shelters when needed.

Simple Shower ThreadsProduct Description:

The Rainburst Simple Shower is a simple solution to staying clean in the outdoors. No longer are the days of holding large, cumbersome bags of water over your head. Now it's as simple as finding a 1 - 2 L (32 - 68 fl oz) bottle, filling it with water, attaching the Simple Shower to the top, and sitting it out in the sun until it reaches a comfortable temperature. The entire shower is composed of just three parts; the nozzle, air relief tube, and plastic bottle (not included). Rainburst states that the plastic bottle is not included because the company is thrifty and environmentally minded. As such, they encourage the user to use a bottle already on-hand. The air relief tube comes in two lengths; one for smaller 1 L (32 oz) bottles, and one for larger 2 L (68 oz) bottles. The shower is also designed to be used with Platypus hydration bags, but may also fit other hydration bags with the same thread spacing and pitch.

Product Impressions:

The Rainburst Simple Shower arrived completely intact and without any missing parts. In inspecting the shipped components, it almost appears as if the parts were made using a 3D printer as the plastic has a very porous and layered appearance. This could be due to the material that is used in constructing the shower; completely recycled material. Seeing this raises some questions about durability which I will definitely comment on throughout the testing period. I am quite interested to see if the air relief line survives a four month testing period without cracking or breaking through repeated packing and unpacking.

The nozzle itself is composed of two separate parts; the base section which screws onto whatever water container one uses, and the head section where the water exits the device. The head contains 40 different holes in two concentric rings. In the center of the head is a larger hole that is used in conjunction with the air relief line. On the rear of the nozzle head is a small port that is slightly larger than the diameter of the included air relief lines. This allows the lines to be fit inside the hole snugly which prevents air from disturbing the water while taking a shower.

Simple Shower HeadThe base of the nozzle has raised ridges along the narrow side that aid in gripping the wet plastic when attaching or removing from the bottle or hydration bag. On the outside of the base towards the wide end are emblems indicating to the user not to use water over 40 C (104 F), a patent is pending, and that the item is made in the USA. It is definitely nice to see that this item is made in America when so many other items like this are outsourced to China. The shape of the nozzle base not only helps evenly distribute the water to the nozzle head, but it can also be used as a funnel to fill the water reservoir after it has been drained. Simply unscrewing the nozzle head in a counter-clockwise rotation exposes the funnel for use.

The air relief tube is nothing more than a length of plastic tube that attaches to the head of the nozzle and sticks into the interior of the bottle. Because a plastic bottle generally likes to retain its shape, replacing the escaping water with air is necessary to prevent disruption of the flow pattern. Without the air tube in place, the water dribbles and flows erratically at times. When using the Simple Shower with a hydration pack the air relief tube is not necessary. This is due to the general construction of a water bladder and its ability to compress when all water contained within has emptied.

One important point to note as per the documentation is to never put any water into the bottle that exceeds 110 F (43 C). I'm not sure why the documentation states as such, especially since Rainburst recommends that the water temperature not exceed 104 F (40 C) during use. The only thing I can think of is that the plastic material might have a lower melting point due to its recycled nature. I'll likely be contacting Rainburst between now and the conclusion of the Field Report phase to get clarification on this statement.

While I'm not usually one to take showers while I'm out camping, having the ability to wash off before bed is definitely going to be a welcome experience. I look forward to seeing how much use I can get out of the Simple Shower and determine if having one is really worth the pack space during long hiking and backpacking trips.

Testing Locations & Conditions:

 My initial two trips were in the area of the Pennyrile National Forrest located in western Kentucky; an open, backcountry area for camping, backpacking, and hiking. The elevation for this area is roughly 450 - 650 ft (135 - 200 m) with slow rolling terrain that has a number of valleys and ridges. Temperatures in the area for both trips were around 75 F (24 C) during the day and down to 50 F (10 C) at night. Neither night saw any sort of precipitation, though there was a bit of light rain during the trip down.

I was also able to get an additional two nights of testing when my son and I were able to attend the 100th Annual Boy Scout Patriot Games at Fort Campbell, Kentucky. The weather was clear to cloudy at times, but there was no precipitation. Elevation was 718 ft (219 m) where we were at on the base, but it was the temperatures that really fluctuated. The high was a nice comfortable 64 F (17 C), but the last night we were there the low dropped to 28 F (-2 C) making for a very cold morning packing up and heading home.

Performance & Summary:

During the past four months, I was able to get a bit of use out of the Rainburst Simple Shower. Finding water in the areas that I hike and backpack is not a difficult task so I was able to use this multiple times to wash my hands and dog, though I did wash my hair on a couple of occasions. I found that after filling a bottle with water, it was better to let it sit out in the sun for a period of time before I attempted to use it. This was true on most days, even the hottest days during the summer where I used the Simple Shower at home bathing the pet. On the first day I washed my hair, early on in the testing phase, I hadn't yet learned to let the water warm prior to use so I was greeted with a breathtaking experience.

The shower itself tends to empty a bottle of water very quickly, even largest 2 L bottles. I found that I didn't really have enough water to wash my hair with comfortably and had to fill up the 2 L bottle repeatedly. To me, this is the biggest drawback to using the Simple Shower. Unless I have multiple bottles filled and warming in the sun, I can pretty much guarantee a cold rinse somewhere in the process. I did find that taking the stem out of the nozzle allowed me to more easily conserve water as I could simply squeeze out what amount I wanted without having to worry about it draining quickly. Still though, I wasn't able to conserve enough to completely wash my hair without resorting to a second, very cold, bottle of water.

The device itself is rather sturdy, and I was able to pack it in just about any pocket I wanted without having to worry about it breaking. I did need to pack the tube and shower head separately though as packing them together both seemed to increase the risk of breaking, as well as take up more room. This wasn't a problem though asI just packed them together in a long pocket so I was able to access both pieces depending upon my needs when using the shower. I did find though that I didn't use the longer tube near as much as the shorter one. Even with a larger bottle, simply placing my finger over the center of the shower head while inverting allowed the water to escape from the holes quickly enough to create a suction causing rising air to prevent water flowing into the tube.

In all, I can attest to the effectiveness and usability of the Rainburst Simple Shower. It does indeed work as expected and does provide a smooth gentle flow of water from the nozzle. While I can see myself possibly using this on longer multi-day hikes, I see this more as a base camping tool since comfort is directly proportional to the amount of heated water on hand, at least for me that is.

I'd like to thank Rainburst and BackpackGearTest.org for providing me with the opportunity to test the
  Simple Shower.
