I have done a lot of hiking over the years but now carry a hammock and
gear for over night stays of one to two nights. I normally carry
approximately 35 lb (16 kg) which includes food and water. My trips are
usually between one to two days duration mainly over weekends. I hike
all seasons with winter temperatures ranging from 39 F (4 C) to 64 F (18
C) including periods of heavy rain at times to summer conditions with
the temperature ranging from 68 F (20 C) to 95 F (35 C) and very dry.
Bibbulmun Track: Sea level to 1,920 ft (585 m). Within this region I
backpack along old forestry roads, sandy tracks, and purpose built
walking tracks. The south-west of Western Australia allows for hiking
and backpacking from coastal plains to forested ranges. I hike in
varying conditions from forestry tracks, to sandy tracks to single
purpose walking trails, from rock hopping, to beach walking to
completely off-track through open and dense bush country.
It is now toward the end of our winter. Though we are still
experiencing some unseasonably cold days with some mornings with
lows of 50 F (10 C) and highs of 68 F (20 C). In another few months it will be middle of
summer and the heat will set in. Daytime temperatures will range during
the testing period, from a minimum of 57 F (14 C) to 100 F (38 C). The average rainfall for
the next few months is, 1 3/8 in (35 mm).

hydration pack is more than just a hydration pack. The pack sports three
quite large pockets inside the main opening. One is for the hydration
bladder and the other two can be used for carrying other gear. These
other pockets are separated by a section of elastic material. This
allows the pack to expand and contract some what.
The bladder slips into the front of the inside pocket nearest my back
and just sits into it. There is no loop to hold it in place. There are
two exit ports on the left and right shoulders for the hydration hose to
pass out of the pack.
The bladder is a 2 litre Source bladder and is very nice. I have one
already that I have been using for years and I am very happy with it.
The lid has a buckle on it to keep the pack closed and is adjustable. On
the pack side of this buckle are three loops that are a part of the
buckle webbing and could be used to attach items on the outside of the
pack. On each side of the pack are two buckles that will compress the
pack. These buckles can be released to allow the side of the pack to
open right out. The front of the pack has some reflective sections to
allow the user to be seen at night if riding a bike for example.
On the back,
that is the part nearest my back are two padded shoulder straps as
expected, they are lightly padded and adjustable. The shoulder straps
have a chest strap attached, this strap is adjustable up and down as
well as tighter and looser. The buckle at the chest has a built in
whistle, which is quite loud. This strap also has an elastic piece
stitched onto the webbing which holds the mouth piece of the tube in
place. The hydration hose passes out of the inside of the pack via a
small opening and then travels down the inside of the shoulder strap
exiting about half way down the strap.
The front of the pack,
notice the two reflective areas.

The pack also has
a waist belt which is not padded and is adjustable on both the right and
left sides. The good thing about the waist belt is that it is removable.
By undoing a couple of hook and loop tabs the strap can be removed. On
the sides of the pack are two zippered pockets, one each side. These
pockets are separate from each other and one cannot be accessed through
Running down each
side of the back of the pack and to the left and right of my spine are
quite thick padded strips. These strips are breathable and should help
to keep me cooler when hiking. Inside the back of the pack sandwiched
between two layers of material is what feels to be a small sheet of
plastic running the length of the pack. This will help the pack retain
its shape when in use.
The pack is
made of a water resistant 60 denier outer shell with a 150 denier ripstop nylon liner. (denier is a term used to indicate the size or
number of filament or yarn. The higher the number the heavier the yarn
very happy with this pack, it looks better in the flesh than it does on
the website. The materials feel tough and hard wearing. The buckles snap
shut with a solid sound. The Source bladder is great. All in all I think
this will be a good little pack for day hikes. I plan to use it while
maintaining my section of the Bibbulmun track where I'll be staying at
the campsite over night and hiking the track to check and correct its

I have now had this pack
for two months and used the pack three times. Twice on afternoons
geocaching around the hills of Perth and once on a day out maintaining
my section of the Bibbulmun track and shelter.
Mark and I who maintain the shelter took another friend of mine along
with our three kids for a short walk and lunch on Saturday.
We parked a little
way from the shelter and hiked in about 3 miles (five km) one way. On
the way in it was a
little warm but it soon warmed up to about 88 F (31 C), the kids started
to moan a little about the heat.
At the campsite we took care of the maintenance that we had planned to do
and had lunch in the shade.
During this time the pack
has worked without a hitch. It is comfortable to wear and will hold
quite a lot of gear.
On the geocaching trips I have just carried a few items. Water, first
aid, a survival kit and some food. On the trip out to the shelter I
packed a little more. I carried the following items.
- A full bladder of
- A first aid kit.
- A survival kit.
- My lunch.
- A pocket rocket
- An MSR cooking pot.
- A map.
- My Nano-7 hammock.
- Cell phone.
- Car keys.
The pack was not full
and I could have fitted a little more in it. I am hoping to be able to
fit enough gear in it to be able to camp out for the night. I will have
to cut my gear list right down and see what will fit soon before the
weather gets cold again.

The pack on me and the
flies on the pack.
After using this
pack for half a day hiking into and out of the camp site I have decided
that I like it. It was not until I had returned to the car and took the
pack off that I found my back was not sweaty at all. I normally perspire
freely on my back when wearing a pack but this time I found I did not.
On the back of
the pack there are two padded sections that run down the length of the
pack. These sections sit directly on my back when I wear the pack. They
seem to be some form of foam encased in a breathable outer skin.
These padded sections kept the sweat away from my back and make the pack
very comfortable. In the photo to the left there I can see the pack was
not adjusted correctly and I need to pull the shoulder straps a little
tighter to get it higher up my back. The shoulder straps have a good
range of adjustment and fit my daughter and me equally.
The pack is adjustable at
the shoulder straps, the
strap and the waist belt.
I took a fair bit of gear along with me to test just how much would fit
into the pack and there was plenty of space for a day's outing. Maybe
even enough for an overnight trip.
In the photo to the right I have shown the gear I carried that day. Not
a huge amount of space left but maybe enough.
Just behind the green front section are two zippered pockets, in these
pockets I carried the map, my car keys and cell phone. The pockets are
not huge but are large enough for flat items. The zipper pulls have a
little rubber knob at the end of each pull and this makes using the pulls a
breeze. They do not slip through my fingers at all. The side straps open
out quite a bit and allow for larger or smaller items.

and my gear.

showing the hose and the shoulder strap.
In this photo on the left I show the hydration pipe running down from
the inside of the pack to the outside by way of the shoulder strap. The
hose feeds up from the inside, over the top of the shoulder and down in
front. I really like this as I no longer have to fumble behind me to
find the mouth piece.
bladder supplied is great. It has no plastic taste what so ever. The
mouth piece works very well although I would have rather had one with a
ninety degree bend in it rather than the straight one supplied.
The mouth piece seals very well and does not allow any water to drain
back into the bladder. So that when I go for another drink the water is
right there and does not need to be sucked up from the bladder.
Also visible is the
black ventilated back padded supports.
Please check back in about
two months for my long term report. I have a ten day trip coming up in
eight days time in Sydney and Canberra where I plan to use this pack
Long Term Report

have been using this pack for another couple of months. During this time
the pack was used for the ten day trip I made to New South Wales and
Canberra. The weather there was very hot with day time temps in the 95 F
to 108 F (35 C to 42 C) range, there was no rain at all.
We were in Sydney for a wedding but arrived a few days early to site see,
there is a lot to see there and tried to cram lots in each day. We did a
lot of walking around looking every where we could and spent one day
walking around Luna park and walking over the harbour bridge. We looked
at the opera house from the bridge and on another day we spent a few
hours walking around the Taronga zoo.
During our stay here I
used the pack to carry our water which was refilled often, the large
opening of the bladder makes this a breeze. The pack would also contain
on a typical day.
- My camera
- A first aid kit
- My reading glasses
- Maps of the area
- Brochures of
places to visit
- Public transport
- Anything bought
during the day
The smaller pockets each
side at the front are ideal for the smaller items, while there is room
in the larger section for my SLR style camera and a few other items.
We left Sydney and went
down to Canberra to my sister-in-law's house to spend time looking at
the sights there. I used the pack every day to carry the same sort of
gear list above. One day we left Canberra and went down the coast into
New South Wales to their beach house to stay for a couple of nights, but
on the way us guys headed up to their block of land they own that is
right out in the middle of no where and just covered in uncleared bush.
The plan was to park the car and make a circuit around the block and see
what we could find. It was a very hot day again and I was happy to have
this pack and the water it carried. I have found the pack to be
quite cool to wear and I do not seem to get a large build up of
perspiration on my back.
We dodged our way around the many wombat holes but we did not get to see
any, I was told that they are more nocturnal and hide during the day. We
did walk up to a very large brown snake and was told to keep very
clear of it which I did.
After a while we stopped in a dry creek bed and had a rest, there is no
water around at this time of year. I pulled some snacks out of the pack
and enjoyed the water from the bladder. The water seems to stay quite cool in the pack.
The first mouthful or so is warm where the hose passes out of the pack
and over my shoulder but it quickly becomes cool. A couple of times when
feeding the hose through the sleeve on the shoulder strap I have had the
mouth piece become caught on the inside helm of the strap. It just takes
a bit of wiggling around to get it to pass through at times.
When I was in Sydney I took the waist belt off the pack and used it
without it. It is just a simple thing to undo the hook and loop on the
belt and remove it from the plastic clip. When out in the bush where I
am climbing over things and up rocks and so on I use the pack with the
belt on. It is easy to remove and replace and so I do it when ever I
This is a nice pack indeed.
The construction is very good and is made of quality materials that no
doubt will last me a long time. The clips and buckles all work well and
I like how easy it is to remove the waist belt. The inside pocket has
stretchy material either side of it and allows for some bulkier items to
be carried. The pack is not large enough for me to carry everything I
need for an over night trip and is better suited to day trips.
If I had to find something that I did not like it would be the hem on
the inside of the shoulder where the hose catches on it. For me the
sternum strap is a must, the shoulder straps kept slipping without it. I
like the way the shoulder strap buckles are half hidden in the strap
itself. I have found the pack to be very comfortable.
So would I recommend this
pack to a friend? Yes I would, I'd tell them to go and get the pack with
the strange name and strange logo and you will not be disappointed.
Thanks Crumpler for the
opportunity to test this nice pack.
