Showers Pass RainSlinger Weatherproof Hip Pack

I‘m in love with the idea of hip packs. No, scratch that. I’m in love with the idea of not having a pack covering my back while I'm riding and I don’t have any aesthetic issues with redistributing some of the essentials to a bum bag. There's a problem though. I've tried plenty of them and up to the RainSlinger arriving I haven't discovered a single fantastic fit.

This 3.5 litre seam welded sack with weatherproof zippers and an adjustment system meant to shape the pack for those of us with less shapely hips has a lot going for it. The quality of construction is obvious out of the box and along with the 69 USD / 95 CAD price tag, I envision it being a popular choice among folks it fits.

I'm a true believer in 'test ride, then decide' and with my previous fitment experiences this is a key concern for me with any packs. Showers Pass addresses the question “where can I try it on?" by covering freight, including return shipping of goods that don't fit, on USA orders over 50 USD and Canuck orders over 130 CAD.

The RainSlinger is available in this lime/grey or a more subtle ochre/grey scheme. The green accents do a great job of highlighting the belt adjustment system (which allows me to adjust the shape of the pack, instead of just cranking down the waist band) but the clay-on-grey is a degree more classy. Surface area contact is limited so the lack of breathability isn't an issue, even on the sweatiest days.

And for the rainy part of the year, the RainSlinger is confirmed weatherproof. For me that’s number one after fit on the features list and, the solid direct ordering program aside, I can imagine these showing up in Cascadian shops when the taps turn on.

The anodized aluminum buckles are easy to adjust and do a good job of holding tension.

I really appreciate being able to quickly adjust the shape of the RainSlinger for various loads.

The RainSlinger also includes a grommet-mounted rear-facing light. It pumps out 10 lumens with three flashing modes from a readily available and easily replaced CR2032 battery. Showers Pass has started to incorporate these grommet lights in rain jackets as well. 10 lumens isn't impressively bright when some rear flashers are pumping out 250+ but when the days get shorter, sometimes unpredictably with cloud cover, I think the little safety button is handy to have.

The included light pumps out 10 lumens of flashing light for about 500 hours from a single CR2032 battery.

Sure, my usual commuter tail light is visible in daylight with 150 lumens and is USB rechargeable but...

...this little grommet-mounted beauty is always there and infinitely brighter than the light I forgot at home.

There is an elasticized mesh organizer inside the main pocket of the pack. It's sort of usable but I'm apathetic to its current existence. If I was making one change, I would turn that into a more structured and waterproof divider. When the rain turns off and I'm looking for somewhere to stash my saturated jacket and I don't want to get all the other contents of my pack wet.

I can cram a lot of stuff into 3.5l of space and I have to be more conscious of the weight than volume of what I'm planning to port when I start filling up this pack. The small outer pocket is a great place to store tools and that's where they live when I'm not carrying what I need on my bike.

Hydration hip packs aren't my cup o' beer anyways but just for the record, the RainSlinger doesn't include a bladder or bottle holder.

I used to equate Showers Pass with yellow rain jackets for salty old commuter cyclists but they make all kinds of kit - review pending.

The accessory chain on the RainSlinger is very usable. I'll strap on a daylight-visible taillight and when the rain stops I'll strap on my wet jacket.

It's nice not to have to choose between wearing a full face and ditching a backpack. I've strapped on chin bars from Bell and Leatt.

I've also been riding the RainSlinger with my Olympus 4/3 camera (with a pancake lens). At first the length and intensity of a ride had to be compromised. There is plenty of space in the Showers Pass bum bag but the weight is too much between my regular kit and the camera.

By moving most my tools back into the Wolf Tooth B-Rad, the RainSlinger is comfortable all day with my camera, a multi-tool, a spare pair of gloves, a snack, and my phone. In this configuration I'll also often port a spare jersey and a shell - like weight products that take up volume but don't impact the fit.

My 4/3 camera, pancake lens, multi-tool, spare gloves, and my phone are a perfect load for the RainSlinger. I also carry an super-light shell if it might drizzle.

I'm very confident in the RainSlinger's weatherproofing but dirt always finds it way into my packs hence the second dry bag for my camera.

If it fits me, it fits everyone? If it fits me it fits no one else? I'm inclined to think it's the former thanks to Showers Pass' adjustment system, and on fit alone I conclude that the RainSlinger delivers real value for its 69 USD / 95 CAD price tag.

With the waterproof factor added in it's a bargain for the year-round rider who prefers not to sport a full-sized backpack but still wants to smartly carry all the tools, food, clothes, first-aid and a beverage. The quality of manufacturing, degree of adjustment, and the lighter-on-than-off weight management when the full 3.5L capacity is overstuffed with gear are delightful.

Showers Pass has delivered a fantastic hip bag in the RainSlinger. Put another way, this is the first fanny sack I've tried that I've actually been happy to use. I recommend checking them out at Showers Pass or asking your preferred local shop about stocking them.

Great review! I’m very interested in getting one now.  How did you strap the chin bar onto the bum bag?

Just used a couple of short straps (these ones have clips but Velcro works good too) through the attachment loops and cinched down. Best to fill the pack first. Works pretty well.

Have you tried the High Above packs yet?? I have one with the Cobra buckle on it. I forget the damn thing is one at times it fits me so well.


The pack I have is in the link. Not cheap , but in all my years of hip packing . Best fitting pack I have worn.

Just been digging around on the Showers Pass site. Anyone try their waterproof knit gloves or socks???

I have a pair of the socks and I highly recommend them as long as there’s room in your shoes. Haven’t tried the gloves.

I did try on a friend’s High Above (he loves it) and it was an okay fit. It wasn’t a love at first fitting experience that would have me dropping $$$. Since this review was submitted I actually tried/purchased a rollrop Porcelain Rocket hip pack and the fit is excellent (for me) - I wanted something I could easily/quickly strap my wet jacket to for on/off days.

In addition to winter rides with the RainSlinger I’ll also be trying a New Zealand made Stealth hip pack with a water proof liner. It looks very promising.

Interesting design with the Porcelain pack.

My High Above has a bottle bag on the side. I stuff my RF pullover in it . It also has a couple of straps you can use to attach items to it as well.

As for the socks , might have to order a pair of them and the gloves

It's interesting how many folks I know who have a hip pack with a bottle holder but much prefer it as a jacket stuff pocket. Do you ever use it for a water bottle in the summer?


mike  - Sept. 10, 2019, 3:57 p.m.

Some times for my dog. I have a bottle on the bike. I always hydrate a lot before the ride.

Which PR hip pack did you get? Of course they are sold out of both the large and small version of their dumpling bag...

I have a regular-sized dumpling. From their Instagram, it looks like there's another batch coming. Every PR is done in batches.

Here's my review of a High Above Cascadia from a few years ago. That bag is still going strong. 



mike  - Sept. 10, 2019, 4 p.m.

Might get one that size for winter use.

Came across this bag , if they can do a billet buckle. I,m gonna try one. Starting to like the idea of the roll top and no zippers.
