[Closed] Bumbag slippage advice (for biffers?)

Fellow Biffer here running camelbak repack which I had to undo the stitching to make waist belt long enough to go round when new. It does get a bit looser but not to the point of slipping right down, but then I may have child bearing hips I guess, or it may be a better design.

My source hipster has detachable shoulder straps which help when the bladder is full.

Put your water in a bottle and attach it to your frame?

Put your water in a bottle and attach it to your frame?

Nice idea, but I have a Jeffsy. I do have the exceedingly expensive water bottle that fits, but it holds something like 500ml, which I find isn't enough for >30°C >2h rides, even used sparingly. Granted, I rarely get through 1.5l but I tend to get through >1 litre on those rides, and treat the frame bottle as a reserve tank. If I'm drinking from it, it's time to start looking for the way back...

It’s a shape thing I reckon. I really wanted to use waist packs and bought a couple, but they both slipped all the time so I sold them. Evoc and Dakine. Am back to an Evoc Stage 12 for light rides and for me, it just works so much better,

I use the same evoc hip pack and have never had slippahe issues(I am young and slim still thankfully) but what I do is carry my silca impero pump in the back comarent to add some rigity and problem solved...

Alternatively have you though about getting a pair of dungarees or elastic pieces and stitching a loop to attach it(can be stitched.. With a thick needle and thimble and caution..but double the stitches up its under a lot of temsion)

Hope that advice helps and watch the velcro part of the straps it's susceptible to slipping if the bag shape changes..

I had the same issue with a Camelbak Repak. In the end I bought a Wingnut 2l pack that sits very low on the back, has shoulder straps but crucially lets your back "breath".

I've had similar issues with the same pack, and put it down to your core muscles being more engaged after riding for a bit - i.e. you hold your belly in!

I would tighten it using the waist strap but keep the side straps loose - then you can cinch those in more easily as and when required.

My Dakine 5L needs the odd adjustment on route but it pretty much stayed put for 14miles today. Most of the time I kinda forgot I had it on

I’m overweight but misses has always said I have bony hips so maybe that helps!

my repack gets looser as the drink level drops in the bladder, not surprising really as 1.5L does bulk it up a lot. an occasional pull on the straps sorts it though and probably no more than twice in a ride.

Is it not just that as you drink from the bladder, it loses volume and becomes looser?

I have this with the Camelbak Repack - the shape of the pack is very different at the end of the ride vs the start. You need to cinch as you sip...

Edit: what bigfoot said...

Repak user here, I prefer riding shorts with belt loops and always wear a webbing style belt with them. I fit my Repak above this and it is aided in staying up. I'm only a 34" waist but I haven't had to tighten the straps, mid ride, more than once this far.

consider buttock enhancing implants ?

Anyone tried both the Camel and Dakine? I like the Dakine, but also wondering how the Camel feels compaared and like the side pockets.

I would tighten it using the waist strap but keep the side straps loose – then you can cinch those in more easily as and when required.

This, as a biffer with the same pack, start with the cinch straps loose, but the main strap snug. As you drink the water, and the pack loosens, just snug the cinch straps up. Keeps mine tight enough.

I find the Dakine a bit tricky to tighten when on due to it just having a side clip and only one strap to clinch tighter.

The bladder is good as I replaced the standrad hose with a quick release version - not something you can do with the Repack?

Still tempted to try one though - looks like it might be a better shape and more comfortable than the Dakine. Only 1 way to find out I guess!!

I think no matter what - some people will get slippage!

I like my Dakine 5L, but it does tend to push my shorts down. A pair of mil-spec suspenders stopped that though.

I'm trying the Bontrager Rapid Pack next trip out. I think most rides I do 2 bottles will be enough. Plus i know there is a drinking tap somewhere close to the middle of all my rides - just need to find it!!

I use a Dakine but as I'm blessed with a booty that would make a Kardashian proud, i have never had it slip down.

In terms of getting the right it to fit "right". Loosen the compression straps, put it on, do up the waist belt quite tight and then when on the bike, tighten the compression straps.

To be honest, I only use it with max of 1L of water in it.  I do have a bottle on the bike though.

More than a 2 bottle ride = hydration pack, for me.

I tested mine just too see how it coped with 2L of water (or more how it felt!). It was not too bad all things considering, but not something I would choose to do!

I am trying to decide what to take on London to Brighton so going through various tests and bags too see whts most comfortable.

If you're wearing a jersey, putting something smallish in the bottom of the middle pocket stops the bumbag sliding downwards, or it does for me, anyhow.

How about using a jersey with roadie style pockets, put your tool pouch in middle pocket, one of these in each side...

....then phone/snacks wherever you can.

I only use a backpack on days where a raincoat may be taken off/put on at intervals - most other days is just saddlebag and jersey pockets

Are hydration backpacks really that bad? I quite like mine tbh - the bum bags appear more hassle than they’re worth to me.

I think if a bum bag fits you and stays put they are great.

Even with mine slipping a little it just feels much better than having a pack on.

I mean this is all kit dependent.

Im going to try the Repack and see how it feels, and also the Bonty Rapid pack and take a bottle on that and a bottle on the frame - therefore giving me around the same amount of water as wouldnt fill up the bladder on the Camel.

Either way I'm not going back to a pack now!

i have that evoc pack. the straps slip over time if you don't set them up right.

Thanks all for the feedback. It's almostly certainly at least partially the water volume decreasing, I hadn't particularly thought of that but it seems obvious now. I'll try and be a bit more diligent with the little side straps and see if I can improve things that way next time.

I really like my camelbak skyline. Fors like a bumbsg but has shoulder straps do doesn't slip or move

Well- thanks to all for the advice. Had a much better experience yesterday with more diligent adjustment of the side straps, didn't really budge too much - just needs a bit of regular tweeking as I drink it seems.

I had a similar problem, and mine would drop slowly the longer I rode - I found the hip pack pro was much better and more secure, and the waist band is soooo much more comfortable ...it’s more expensive, yes, but less annoying !! I have kept the other one for walking adventures

Na, they work perfecgly well, way better than a backpack for pretty much everything except big days in the mountains.

I have tried a few now.

Tried the Camelpak and found the straps a bit strange, They have integrated the straps with the straps to tighten the load and found it really difficult to lossen the bugger at all round my waist! Also - the bladder is not the easiet to get out and due to teh massive opening and plastic cap it takes up so much room!

The Dakine 5L is actually the most comfortable - the clip sitting at the side seems to make it better as I find the centre clips dig in a bit.

I have added a bottle to the bike now which allows me to just keep the bladder a bit lower and have also got a dakine 2L when I want to go no bladder!
