Waterproof Cycling Ruck sack / Rucksack / Back pack / Backpack / Backpacks

You know Jordan (bigxtop) will customise your bag for you?
Just ask him.

Been using my Banjo Bro's bag for the last 3-4 years and it's still holding up well. Completely waterproof.

I also like the fact it's just one big compartment so you can put tool bags in, big boxes that sort of thing. I could manage with a smaller bag but it's always the times when you want a bigger bag you don't have one.

Reasonably priced too.

where in UK you can buy one? Could find US site only.

Going to be that person who recommends rack and panniers, or saddle bag. Take the weight off your back when riding.
Ha! +1
I've mostly ditched the Mission Workshop now I haz bin Scoblefied. Now I over fill the Ortliebs instead.

I've just had a mad ebay spree and bought two 70's-80's ish Karrimor rucksacks. A 65l Haston alpiniste and a 40l ish Joe Brown, both for cheaps. Might only keep one of them depending on my needs so if anyone feels the urge for some retro outdoor chic(they're not pretty but certainly bombproof) then let me know...

Are there any backpacks with vented backs that will hold as much as a fully compressed PAC Ultimate that are actually waterproof?

Someone buy this before I'm tempted to add it to my collection. Og Karrimor is always comfy and built to last.

Things you can fit into an Ortlieb Velocity:

• a sixpack of German Beer, 0,5l each.
  
• 1kg of Haribos in a box
  
• 1,5l bottle of non-alcoholic drink (to fight the hangover)
  
• 2 boxes of chocolates
  
• rain jacket
  
• keys, lights, misc. stuff.
  
  

I like this backpack. But all that stuff is really pushing it. 20l isn't a lot appearently

I'm looking to replace my Chrome Falcon, so in the market for a ~35 liter backpack with a u-lock pocket on the side and my budgets >150 euros. Any suggestions?

I'm looking for a smaller bag for commuting. Anyone used one of these? The Ortlieb Velocity looks a bit 'simple' - I like to separate my bits and pieces.

Does anyone know if the mesh "harness system" of T-Level Infinity really does improve airflow and ventilation? I'm getting fed up of my bags getting caked in white sweat marks after a week's commute (Mission Workshop Rambler, Goruck GR0, etc).

@JB, @dimi3, what you reckon?

You reckon?
I can't afford a new bag and i do like my Burro roll top but there are things that could be vastly improved

Yep much better; dom you are welcome to borrow mine if you want to try

I am actually using a cheap running backpack with mesh like this to avoid sweaty back atm:

There is hardly any storage but it works for me to carry clothes to work etc. And it was £15 from Amazon

I use this:

It used to be £7, and it has lasted for 3 years of near continuous use running and cycling.
Its not waterproof, and if you can't leave shoes at work then you're screwed. However, if you use a plastic bag to protect stuff from wetness, and only need to carry shirt, lunch and trousers (and underwear and socks), its pretty incredible.

Plus its really good for trail runs.

Its a real looker too ;)

My mission bag is a total sweat box. Absolutely hums after 5 years of use.

I've got a bagaboo Rancid for commuting. nice size. upgraded with full waterproofness and their airflow back padding. I really like it.

On a hot day can still get a bit sweaty, but as will anything else.

Any pics cake? Esp of the padding. Phone pics would do; missus wants to get a new backpack ..

Got an Ortlieb Velocity. It's not that great in terms of un-sweatyness.
It has these panels that will leave nice sweat imprints on your back.
But then it's absolutely bombproof which sure is nice.

Got one of these too, one of the best purchases I've ever made. Considering it looks like a brick, it is surprisingly comfy, even on long rides. Had mine for over three years and still as good as when I bought it.

You do get a sweaty back, this is unfortunately true.

Have recently got a Velocity. My back is no more sweaty than with a normal/non-airflow backpack or a large courier bag, and it sits on the back nice & comfortably.

It's at home at the mo. remind me and I'll snap it later/tomorrow, or feel free to have a look in the flesh at some point.

No sweaty back....gets lunch, fresh shirt undercrackers, socks and tools in. Why use a backpack? for office commutes. I have a 40ltr back pack for anything else, but this rarely comes commuting.

I like to carry a 1.5l bottle of water wherever I ride. Would that fit?

Why use a backpack? for office commutes.

Laptop :(

They are handy for when you do want to carry more. I have to cart clothes and towel and toiletries around the office so having extra space is good. I guess I could just use a shopping bag or something but then what happens when I order stuff to be delivered to the office (like this 20kg of Torq bars I have next to me).
Also, don't like extra weight on the bike for some reason. Changes the handling a bit and my pump wouldn't fit in that saddle pack. I like the idea though
