Siskin 12

The best way to describe Osprey’s Siskin 12 is that it is pretty much the hydration backpack equivalent of the Swiss Army Knife, it has everything you need and more!

As you can see from the FULL list of features below Osprey has shoved as much as they can to make this bag all you will ever want and need, I will be talking more about some of the best features I believe the Siskin has to offer but first of all some of you who go out on epic rides or prefer to keep tools in their bag rather than on their bike would be saying Osprey are missing a roll out tool-wrap and you are correct to some degree but the Siskin isn’t for those type of rides or riders because that’s where the Raptor comes in which I will be reviewing at a later date.
But no matter how far or how hard you ride all riders need to carry some tools and spares so they have included an “Internal organiser for bike specific tools and spares” which should be enough to cover you and if not you can always put more tools and spares into the main storage compartment of the bag.

One of the best features for me was the “AirScape™ backpanel with large central ventilation channel”, when you think about it it’s a simple solution but yet it’s so effective and until you go on a ride with a backpack and you either stop off somewhere or when you get home you’re soaking with sweat underneath the bag and your jersey or cycling top is stuck to you with sweat.
The AirScape is designed so effectively that it works perfectly while still being so comfy on rides!

Don’t underestimate how much the Siskin can carry, I would say it looks a relatively small and compact bag how even when the reservoir is full there is still plenty of room and pockets to fit all kinds of equipment, clothing, snacks, spares etc, there are a multitude of different size pockets with different openings and materials which suit different objects and products and there are even more reinforced pockets for the more bulky or heavy objects.

Even though you can quite clearly tell they have put a lot of thought, research and development into the new line of bags they haven’t forgotten the little yet very helpful other features like glove friendly buckles, internal key attachment clip, LED light attachment point, LidLock™ bike helmet attachment and reflective graphics just to name a few.

Once you get the Siskin in your hand you can tell from the feel of the material it has been made for the roughest trails, riders, rides and weather which is means no matter which country your planning to ride in next or if you just stick to trails in your own country whether it’s warm and dusty or cold and wet the Siskin cn easily take them in it’s stride!

Further Info

Bite Me. Designed for days on the trail, the Siskin 12 is a technical and high-performance hydration pack which balances tough and durable construction with impressive organisational capacity and a progressive, stylish aesthetic.

Siskin features a comfortable Airscape™ backpanel with large air channel, promoting air-flow during hot and humid conditions whilst hugging the body closely with a stable and comfortable fit. Held in place by a breathable, pocketed hipbelt and performance-fit harness, Siskin will stay put no matter how hard you need to pedal. The integrated 2.5L Hydraulics Reservoir provides easy access to water, keeping you hydrated throughout your ride, and you’ll never be left searching for your bite-valve thanks to the magnetic retainer on the pack’s sternum strap. Talking of magnets, the sternum strap has an innovative closure mechanism, allowing you to open and close it without taking your eyes off the trail.

Internally, the Siskin features a large central pocket, with multiple internal organisation options such as side-mounted pump pockets and multiple zipped mesh pouches. This is all accessible through a full-length opening, allowing you access to the whole contents of your pack, ideal for when you need to fix a mechanical or find a snack bar. Siskin’s front shove-it pouch provides an easy place to store a wet jacket, but also makes carrying a full-face helmet easy, while the Lid-Lock™ allows a storage place for a traditional bike helmet. For storing your sunglasses or small essentials, there’s a scratch-free pocket inside the front panel, alongside a brightly coloured clip to ensure that you’re never separated from your keys.
