What's It For?
The new for summer 2008, Z25 is, says Gregory, intended to be the
ideal size for 'multisport' activities and 'to be the pack you grab
90 percent of the time on the way out the door'.
In other words, an all-round day pack that you can use year round
for walking, scrambling, maybe even a bit of mountain biking with the
trampolene-style Jet Stream suspension intended to keep things cool
when it's hot outside.
The Techy Bits
One of the things we like about Gregory is attention to detail -
there are loads of neat little touches on the Z25 that you appreciate
in use, but the fundamentals of the sac are down to the back system
and suspension.

Like the Z30 that impressed us when we tested it, the Z25 uses
Gregry's Autofit harness system, basically a neat and simple top
shoulder strap mounting system that rotates to conform to your neck
and shoulder contours., so the harness mirrors the slope of your
shoulders and the width of your neck eliminating rubbing and hot
spots. The nice thing about it, is that you don't have to adjust
anything, it's all to do with how the straps attach to the pack.
The other key to the Z25 is Gregory's Jetstream DTS suspension
which uses two rods to transfer loads into the hip-belt, a
trampolene-style mesh sheet to vent your back and the DTS harness
yoke which, Gregory says, increases the stiffness of the frame as the
pack load increases to give maximum comfort.
How It Performs
We've been using the Z25 for several months now and its quietly
wormed its way into our affections. For starters, with modern,
lightweight kit and clothing, 25 litres is quite adequate for most
days out, but should you need it, the big back stash pocket gives
extra capacity plus handles soaked waterproofs nicely.
Underload it though and side compression straps keep everything
neat and tucked in and - a nice touch - as with big brother Z30, the
lower strap can be positioned under the side stash pocket so it
remains useable. Plus fast release buckles allow easy stowage under
the straps if needed.

We also liked the two mesh belt pockets, which are ideal for
carrying snacks and small, often used items like, say, a compact GPS
unit. One thing traditional pack users may miss is a lid pocket,
though Gregory provides a small, zipped hanging pocket that'll take a
wallet and phone instead. The pay-off though, is easy access to the
innards via a big zipped front panel opening making packing and
decanting of pack contents pleasingly straightforward.

All of which would count for nothing if the Z25 didn't carry well,
but the good news is that it does, very well indeed. It's mostly an
unobstrusive experience, which is how we like it and was quite happy
with loads of up to around 12 kg. The shoulder straps are well shaped
and sit neatly while the back system does a good job of transferring
weight down into the wide hip belt and spreading it across the back
generally.
It also sits low enough to use on a mountain bike without fouling
the rear of your helmet on descents and seems generally well made and
put together.
Another well thought through and very effective day pack from
Gregory. The back system carries well and gives some ventilation
without sitting far enough away from your back to lever the pack
outwards and the detailing works well - you can reach stash pockets,
stow poles easily etc.

The Z25 really is a very good all-round day pack and almost on a
par with the class-leading Osprey Atmos 25. We say 'almost' because
for us the Atmos's spookily effective magic carpet carry just sneaks
it, but it's a close run thing.
Available July 2008.

Good carry, great detailing and well thought through.
Nothing really though some might miss a conventional lid
pocket.
