In my opinion, in this weight category, the comparable Fjord Nansen Finmark sleeping bag performs poorly. This sleeping bag really stands out for its lightness and warmth compared to other synthetics. The additional, adjustable collar on the chest is very effective at retaining warmth. The zippers are exceptionally sturdy and don’t jam like they do in other models available on the market. The material is pleasant to the touch, and unlike other sleeping bags, light doesn’t pass through it at all. The whole thing gives the impression of being a down sleeping bag. It’s very warm and I’m extremely satisfied with it.

Alpinus Ultralight Pro 850 Sleeping Bag Orange/Navy - left
The mummy-style sleeping bag in vibrant orange and dark blue offers a natural form that aligns with the body, providing restful sleep in the wilderness. Crafted from lightweight yet sturdy 20D rip-stop nylon, it includes a damage-resistant exterior. The dual-layer construction and Alpinus DualTherm insulation filling ensure high-performance thermal protection while maintaining a low overall weight.
Temperatures and conditions of use
The usage temperatures of the sleeping bag are defined according to the EN 13537 standard:
- T-comfort: +8 deg. C - the lowest temperature at which a woman can sleep comfortably all night,
- T-limit: +4 deg. C - the minimum temperature at which a man can sleep without discomfort,
- T-extreme: -11 deg. C - the lowest temperature at which it is possible to survive in a sleeping bag. This is not a recommended value for standard use.
Durable nylon, Alpinus DualTherm insulation filling
The material used in this model is characterized by good water vapor permeability, which facilitates the removal of moisture to the outside. The outer surface is made of reinforced 20D Rip-Stop nylon, which increases resistance to abrasion. The DualTherm insulation is a synthetic, anti-allergic insulation that retains its heating properties even when wet. At lower temperatures, it effectively retains heat, and at higher temperatures, it prevents overheating. The sleeping bag is machine washable, and the included loops make it easy to dry it on a hanger.
Left-side zipper, Anti Snag system
The model is equipped with a two-way zipper from YKK, located on the left side. It allows for full unzipping or only partial unzipping from the bottom, which improves ventilation. Thanks to the Anti Snag system, the zipper does not get caught on the material, and an additional lock prevents accidental unzipping while sleeping. The interior contains a small zippered pocket - perfect for small items.
Integrated hood to protect against the cold
The integrated hood of the jacket effectively protects the head from cooling down, increasing thermal comfort in low temperatures. Its anatomical shape also protects against wind and moisture.
Convenient transport and storage
When folded, the sleeping bag measures a compact 30 x 17 cm and 25 x 18 cm when compressed. Thanks to its low weight of 850 g, it is extremely handy and does not add too much weight to your equipment.
Set elements
The set includes a compression sack with sturdy buckles, which secures the sleeping bag during transportation and protects it from dirt and damage.

YKK zippers

Anti Snag
Anti Snag is a technology used in sleeping bags to prevent the zipper from snagging.

The sleeping bag has been used only once so far by my children during a camping trip and it worked great. It performs excellently in a tent, and in the summer it may even be a bit too warm ;) I definitely recommend it.
