I'm happy with my 10L Deuter EXP 10, but I'm looking to buy a roomier bag (20+ L) for longer daytrips or overnighters.

- Not a huge rush to get one, mainly looking to be pointed in the right direction
- Being in Singapore/Australia, the weather can get stiflingly hot, so airflow is very important
- For MTB and commuting (might be carrying a small laptop from time to time)
- My current frontrunner is the Osprey Talon 22, any comments with personal experience of this would be appreciated.
- Would be a MASSIVE plus if it comes in orange (preference and high visibility imo)

Thanks in advance!

Can't do it. Even if I tell you what pack I'm rocking there is no guarantee that you could find it in Singapore or even whether it won't be suddenly discontinued for one reason or another. When you are ready to spend money go to your friendly neighborhood outdoor equipment retailer (or their website) and look around.

Fair enough. I will get it from a local retailer if I can, and I have done some walkabouts in the malls. My Deuter was purchased based on a friend's recommendation and finalized by Internet reviews. I don't mind spending more if I know the quality and utility is solid.

You could try something along the lines of a Camelbak, I'm fairly certain they make something along the lines of a day bag. But like Leisesturm said, can't really recommend anything specific.

there are some daypacks with a tensioned mesh back panel . Im not in sales, i dont know brand names.

but for the place you are, Equatorial, Klick Fix has a backpack you hang on a seat post bracket while you ride,

Then it pops off to put it on your back when you are off the bike. IE its off your Back when on the bike.

the seat post mount is usable with many Klick-Fix products + Ortlieb handlebar bags ..

No guarantees any of these are obtainable in Singapore. You may have to order them online and get them shipped, which will not be cheap.

Boreas makes some semi-modular packs where the pack is suspended on a frame with a mesh back, such as the Bootlegger.

I haven't personally use the Boreas packs, though.

Tout Terrain (German Bikes) dropped making their seat post mounted rack & removable back pack ..


there was a 3 section pannier that worked as a back pack when you tool it off the rear rack.

nothing separated to go on the rack it just clipped on and folded over..

At that volume, why don't you strap a duffel bag or sports bag to your rear rack?

I'm not a fan of wearing a backpack when I ride. I understand everybody has his own preferences. 20 L is pretty big. In fact I've gone through experimenting with many bags and currently I do have a large volume packpack strapped and bungeed to the rear rack.

I tried a 20L Osprey cycling pack, liked it, but it had too many 'cycling features' that I don't use that cluttered up the 20L available. So now I am using a 30L osprey cycling pack and it is nearly ideal.

Actually in between I tried a 30L Osprey non-cycling pack and I could not ride with it at all (internal frame for daypack jammed into my neck...) but I really loved that pack for hiking and travel. So now I have the 30L cycling pack for commuting and a 40L version of the original non-cycling pack for non cycling.

I'm one of those who generally don't like cycling with backpacks although a small hydration pack (enough for up to 3L water plus a seat pack worth of extra stuff) is sometimes acceptable. However, for day trips and overnighters where I would need more space, I'd go with a rack pack, the new bikepacking saddle or handlebar packs or a small set of traditional touring bags (ok, maybe the last for an overnighter, not a day trip). Futhermore, Singapore, I understand can be hot and humid, I'd rather have nothing on my back in those conditions.

Or get both. Can be used as a backpack or a rack pack. I use it as both configurations. On my back for one bike, on the rack for another.

Whatever you do, don't get a pack with a hard frame that goes against your back. I have a pack that's perfectly comfortable when I'm using it while hiking, but when I'm biking the curve that generally goes into the small of my back jams into the center of my back. Very uncomfortable.
