Rock + Run Hipsac

13 reviews   |  

We started making the Rock + Run Hipsac in the workshop behind the Ambleside shop back in 1984. This was the advertising slogan:

“Carry anything from a banana to a brick without bounce.”

Running bum bags were very basic then, most bounced badly and were quite heavy having their routes in the ski industry. Our aim was to design something that was lighter, just big enough for the essential long fell race requirements and crucially, didn’t bounce.

The bounce issue was solved with side compression straps and, we were the first company to use this design feature on a running bum bag. Lowe Alpine followed a couple of years later.

We sold 1000s in the early days and they were the fell running bumbag of choice for several years. Today running pack designs has evolved into a complex range of products some of which are arguably, over designed.

Our motivation in relaunching the Hipsac was to bring some simplicity and freedom back to fell running (although this versatile little product works well for road running and cycling too). Ask yourself how much stuff do you really need to carry and if you can’t fit it into a 4 litre Rock + Run Hipsac, am I carrying too much?

The best product designs are light, simple and functional. We are confident that the Hipsac continues to meet those criteria.


What The Rock+Run Team Say

"I’ve used it on countless wet and grim mountain bike rides, taking no care of it and jamming a lot more stuff in than it's designed for, and it's still going strong. The simplicity is its greatest feature which in turn helps with its stability and comfort. Just your phone and keys for a short run, no problem. Waterproof, pump, tools, a tube, some lunch and your phone and keys for a days mountain biking? It can do it." - Matt

Rock + Run Hipsac

My original Rock and Run Bumbag was looking rather tired; after around 40 years (!) of regular use in the hills, on the bike, and in air and train travel it was time for a well earned retirement. And there was an easy choice for a replacement as I was delighted to find R+R had re-launched the (now called) Hipsac with the same simple but highly effective design. A single four litre compartment plus the bag's USP - the side compression straps - gives a comfortable, bounce-free carry however much or little you pack. Different, weatherproof fabric, a two-way zip and bright colour choice all very welcome. First class kit.

Perfect Waist pack for running or cycling

Brilliant. When cinched up the items inside are stabilised perfectly, whether just a phone or phone+waterproof+soft water bottle+snacks. Super lightweight sack.

Very happy

Love the hipsac, still bounces around like most bum bags but the straps on the side really stop most bouncing. And much nicer to have that bag on rather than a running vest

Simple but effective

Purchased to replace an early Rock + Run bumbag bought from the Ambleside shop in the late 1980’s which had finally given up the ghost (after a lot of use and abuse). This version is slightly more technical (with the addition of a double zip and reflective strip!) but has lost none of that early DNA. Light and functional - I hope it lasts as well as my previous version.

After 30 years it’s still the best bumbag for short to medium fell/ mountain running. Sits in the small of the back with no vertical or lateral movement. Perfect
