Observations when I first got this bag were it seems to be a quality stitched bag. The bag on the scale measured 3 lb 7oz, which is lighter than listed. The overall bag and compression sack weighs in at the 3.65 lb mark however, so maybe this is what is actually specified. Also to be fair, I know that nylon will gain weight when it is humid, and it is winter time right now, which could possibly account for the 0.1 lb difference.
As of today, I have used this sleeping bag twice. Both nights had a low of around 5 degrees Fahrenheit. My setup consisted of a US military Gore-Tex bivy sack, a sleeping pad, and this sleeping bag (High Peak USA Alpinizmo Latitude -5). The first night I slept outside in this I used a ˝” thick polyurethane close-cell foam pad (Wenzel) with an R-Value of around 2 – 2.5, which as it turns out was a little low for sleeping on the snow. I slept mostly with the bivy sack open, and felt warm most the night, until I awoke to snow melting on my face. At this point I close my bivy sack up to keep the snow off of me. Overall I did feel the ground starting to get cold, but it wasn’t unbearable, and I mitigated the cold ground feeling by rolling onto my side. In the bag’s rating description it states that the -5 rating is for an enclosed space with an insulating mattress underneath the user. The limitation at 5 degrees, as it turns out was my sleeping pad, and not the sleeping bag. The second night I slept outside I used the same US military bivy sack, and this sleeping bag, however I picked up a Big Agnes Hinman sleeping pad which is rated for use down to -5 degrees Fahrenheit, with a claimed R-Value of 5.5. I figured this setup would provide good insulation from the snowy ground. Sleeping outside with the new setup I did not feel the cold seeping through from the ground, and overall I was more comfortable than the first night. The Latitude -5 bag has a very good draft collar for sealing the bag off around your neck. At 5 degrees I cinched this up all the way closed, but not as to be tight and uncomfortable. The draft collar makes a huge difference, as before I was using it that night, I did feel a bit uncomfortable.
Another thing to mention about my setup is what I was wearing. Both nights I was wearing long underwear, top and bottom, with a balaclava to keep my face and head warm, and wool socks. The balaclava is a key component for me, as I hate the feeling of my nose freezing off my face! Overall the second night I felt comfortable, even with the bivy sack open. I will note that both nights the weather conditions were calm winds; otherwise I would have needed to close the bivy due to forced convective losses in heat. One area of this bag, which I feel is a slight weakness, is the draft tube running the length of the bag. This draft tube feels a bit small for a -5 degree bag, and when sleeping on the side with the zipper in the air, I did feel as though I was losing heat through the top. If it was any colder than 5 degrees I don’t believe sleeping on my right side would be comfortable. I am not sure how warm this will be at -5 degrees, but will post more when I find out.
Key features I like:
• Elastic draw cords - When drawing this down all the way it is nice to have a little give so as not to feel as claustrophobic.
• Zippered pocket inside the bag: Nice for storing valuables such as a headlamp, wallet or cell-phone.
• Warm foot-box – I usually have problems with cold feet in most bags, but not this bag! This was a nice surprise to have in the winter.
• Draft collar is beefy and closes in around neck to keep in warm and cold air out.
• Has a nice compression sack which can be compressed to around 11 x 9 inches (Normally 18 x 9 inches I measured).
• Compresses very well into its stuff sack for a synthetic.
• The cut of the bag makes opening and closing the zipper from the shoulder up very difficult – Not deal breaking difficult for me because I am young and flexible, but I could see this as a problem if I was older.
• The draft tube seems to be the bag’s weakness – not sure how warm it will be one it gets to -5 degrees.
• I didn’t see anywhere if the external fabric had a DWR finish or not. It is important to have in a bivy sack since moisture will be unavoidable. I added a Nikwax DWR finish; to be sure it wouldn’t be an issue.
