Grundens Bike Poncho

This poncho was in the works for 18 months. After four prototypes, we have what seems to be the perfect poncho. Considering that a poncho is little more than a roundish piece of fabric with a head-hole in it, that may not mean much, but it is true nonetheless.

For one thing, the fabric is fire-hose proof. Grunden's makes serious foul weather gear for cod fishermen on the rainy open seas, and nobody on earth knows rain 'bric like Grundens does. We tried a couple of different weights and went with the slightly lighter one, because it squashes down to a smaller size when you pack it away.

It's yellow for visibility. No half-blind drunk can miss it, but if you wanna be sure, buy a strip of this tape, round the edges and lay it on, and it should stick there for a while. At some point it may peel off, but it's still better to stick it on than to sew it; and no spray-on shines nearly as well.

There's the expected waist strap and thumb loops, a gusset at the neck, and a drawcord. No head-covering, so you can wear your crash helmet or a rain hat, and turn your head without looking at fabric.

Two sizes: Medium fits to 5' 8"; L fits 5' 9" and up. If you're 5' 8.5, you're out of luck.

Get a Brooks poncho for $290; or a Carradice. They're both fine, no doubt. This Grundens is by no means the only good bike poncho in the land, but we worked with Grundens on what few details a poncho actually has, and it came out just right.

Whenever you have to ride a few miles in a downpour, this is the thing to wear. It'll keep you dry from neck to a bit below the knees. Combined with MUSA Rain Pants (we used to sell these, can't anymore, and won't, so find some rainpants elsewhere) and Musa Splats, and you're all set.

Bike ponchos favor--that is to say, they work best---with a more upright riding position. This Grundens should last you 20 years, and won't ever leak or require maintenance.

really fantastic November 19, 2015
Reviewer: lucky blau from Eugene , OR United States  
I'm glad I was able to try both the M and L at Riv headquarters. At 5'10" I am borderline for size. It turns out for my purposes (I ride 54cm Surly LHT with drops) this size is perfect, forming a fairly taut but not restrictive tent over the bike and myself. As noted, the bike kind of "disappears" below this thing, meaning it provides excellent coverage--way more than I am used to. It extends WAY over the bars, which is nice (my previous cape had a tendency to inch back over the levers). Also as noted, it's tough to execute hand-signals with this thing on, but that is a draw back of any rain cape. Also also as noted, it's a heat trap, but on the plus side, it does not stick to damp skin. Initially, it's a bit difficult to get the rear portion over the back of the saddle, but once it's there, it feels good and doesn't move around a great deal. Totally recommended if you have to deal with rain and don't like getting wet.

Too narrow April 18, 2015
Reviewer: Johan Larsson from Gothenborg, Sweden  
Unfortunately this poncho was a big disappointment. I'm 6'2"/188 cm, and I can only use it on one bike I have that I sit completely straight up on, that have a short top tube, and have a narrow porteur-type handlebar that sweeps back. It's dangerous to use on my other bikes, because it's so tight around the handlebars that it locks the steering. I can't even use it on my old mountainbike that I also sit upright on, because the handlebars are too wide. Since it's basically unusable, I have been thinking of cutting it up and try widening it, gluing in some pieces, because it would be truly great if it would be a bit wider. Well, "unusable" is not correct actually - in fact I must admit this poncho works extremely well on that one bike mentioned - but that makes it the more frustrating not being able to use it on the bikes I ride the most. The circumference around the hips and handlebars would need to be maybe 20-25 cm/8-10 inches longer for it to work for me on "normal" bikes.

Mixed but mostly good April 8, 2013
Reviewer: P.S. from San Francisco, CA United States  
Best Solution

The Really Good: ventilation compared to synthetic rain jackets, aka zippered plastic bags; not as big an advantage when the poncho's tied around your ribcage with the inside cord and the fabric is pulled close to your back;
The Really Good: your bike literally disappears beneath you; all you can see is your front tire; feels like you're a giant floating yellow blob, which is fun;
The Good: Visibility; ease of packability;
The Less Good: is a bit clumsy to get situated correctly on your body and the bike -- needs frequent adjustments if you commute with lots of starts and stops; no way to signal with your arms;
The Less Good: Price, although the fabric has a nice, non-plastic feel and it's a good investment in a long-lasting piece of equipment.

All in all, probably the best solution for riding in the rain, when coupled with shoe covers or gaiters for your feet/lower legs. If you ride in the rain in this thing, you will get wet, but not terribly, and not from sweat. You can also wear it while walking your kids to school in the rain and have a lot of fun embarrassing them.

Works well February 7, 2013
Reviewer: Keith from Worthington, OH United States  
I've had this cape for about a month now and used it for a short ride in heavy rain and a couple of longer rides in steady rain.  I like it much better than rain suits, which leave me bathing in sweat, or non-bike ponchos, which usually don't fit right or cover the right areas for cycling.  It's comfortable, it fits me and my bike, and I found the thumb loops work fine with Albatross bars.  I've also been able to ride with the handlebar light uncovered without a problem.  Rain does collect at the front of the cape, but it's not difficult to bail it over over the side every so often. With the Grunden's hat I can be a model for the guy on the fish sticks box. Update: I wore this on a 50 mile bike camping ride during which it rained all but about 10 minutes.  Stayed dry. 2nd Update: I've used it a lot now and  it's worked great every time.

Some good, some not so good June 1, 2012
Reviewer: Anonymous Person from Cranberry Twp, PA United States  
Not designed for a woman. Thumb straps are too far out. The medium (smallest offered) came to mid-calf. Almost impossible to signal a turn. Too much material to get free of. Awkward and clumsy and maybe borderline dangerous to attempt. The good: Light to moderate rain, the only things wet were my feet and face   Seat, handlebars, most of the frame and part of rear rack were bone dry.  Issues:  The front blows up if not pulled down well over the handlebars.  Knot on the thumb strap caused numbness in my hands.  I eventually took my thumb out of it altogether.  Handlebars end up totally covered so the light & reflector are concealed. If you want the light to help to be seen in the crappy weather you're out of luck.  (On the flip side, you're covered in a huge, bright yellow tent, so maybe the light isn't such a big deal.)  The neckline cinch strap is on the inside so when you tighten it, the plastic knob rubs on your throat.
