Mummer PrimalLiner Series Report 3
Primalliner by Integral Designs
Tester: Thomas Vickers
34 years old
The weather in Texas has not cooperated with my tests, but I have gotten to
spend 4 nights in the Primalliner. What I really wanted was some nice
temperatures in the mid to high 20's, but nature was not willing.
Needless to say, the primalliner has proven itself to be an interesting
piece of gear. Some of my earlier worries did not pan out, but other
problems did become apparent with use.
My first experiment was packing the bag. My first attempt was to stuff the
primalliner and my bag (Peak 1 Quetico) into a Granite Gear Compression
Stuff Sack, size small. I might have made it, but I wasn't willing to fight
that hard. I finally got both into a Medium sized Granite Gear Compression
Sack with no problem. The liner will fit nicely in a small sack by itself.
So off I went, pack stuffed for a few nights of out door sleeping in the
Piney Woods of South East Texas.
The first 3 nights I used the primalliner outside, the temperatures ranged
from 65 degrees F to 55 degrees F. The temperatures outside my Eureka
Gossamer were probably lower, due to wind, but things were very comfortable.
I was able to sleep in the liner with my arms outside of the bag with no
problem. In fact, it was very comfortable to use this way.
I could get the zipper closed and arrange myself very easily with my arms
exposed. The problems I encountered with the leg area being tight were not
apparent when I really got down to sleeping.
The outside lining (1.1 oz parachute nylon) proved to be much less slippery
than the outside of my sleeping bag. I did not slip and slide on my Ridge
Rest Deluxe pad like I do when I use my Peak 1 Quetico Bag.
As a stand-alone bag, the primalliner worked very well in the mid 50's to 60
's. I spent three nights in varying conditions, most were fairly humid, and
all were in a tent.
My last night out was Christmas Eve. I was staying at my future In-laws
house and heard that the evening temperatures were going to drop into the
low 30's, maybe even the 20's. So, out came the tent, sleeping pad,
sleeping bag and primalliner.
The first couple of hours were spent sleeping the way I had the other 3
nights. I used the sleeping bag as a pillow and slept with my arms out of
the primalliner. As the temperature dropped to about 45 degrees F (kind of
hard to read the thermometer in the middle of the night) I had to curl up
inside the primalliner and keep my arms inside. This is when I had my
difficulties. It was very hard to get completely inside the liner, zip it
closed and get comfortable. The chest area was too tight to sleep well with
my arms inside the liner. This wasn't a problem for long, because sometime
around 2 a.m. the temps had dropped to about 37 degrees F. I was too cold in
just the primalliner, so I kept the liner on, and slid into my sleeping bag.
This allowed me to keep my arms outside of the liner, but inside of the bag.
I was very comfortable until I was rousted Christmas morning by my fiance
and her mother. Sometime during the night the temperature dropped to about
34 degrees F, but I slept comfortably in the liner and my bag. I probably
didn't need the liner (bag is rated to 32 degrees F), but I did not overheat
either. The night was rather comfortable, despite very high winds and the
low Texas Temperatures.
My main problems with the primalliner at this point are the tight confines
in the chest area. If you want to seal yourself inside of the liner, it is
quite a task to crawl in, zip up, and stay comfortable. I am not the
largest person, so I can only imagine how someone bigger would feel inside
My other concern is the lack of a full-length zipper. While this saves
weight, this bag might be too warm when used alone in temperatures above
65-70 degrees F.
What I am now looking forward to is a prolonged test of the liner. I am off
to the Buffalo River in Arkansas for 5 days in March. The liner is going
along, possibly as my only bag. I have a plan stuff it in a 2 gallon zip
lock bag and use it in the back of my Golite Breeze. Not sure if this will
work, but this trip is going to be a test of the Breeze, the primalliner and
some other light weight gear.
Overall, the Primalliner gets another good rating. It is well made, easy to
handle in a small tent, and keeps me plenty warm. I would prefer to see a
roomier cut and a longer zipper, but that may just be me dreaming of the
'perfect' piece of gear.
