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 synthetic competitors. The additional drawcord collar on the chest very effectively retains heat. The zips are exceptionally sturdy and do not snag like in other models available on the market. The material feels pleasant to the touch, and unlike other sleeping bags, light does not pass through it at all. The whole thing gives the impression of being a down sleeping bag. It is very warm and I am extremely satisfied with it.

Alpinus Ultralight Pro 850 Sleeping Bag Orange/Navy - left
The mummy-style sleeping bag in the energetic color combination of orange and dark blue ensures a natural fit to the body and comfortable sleep in the great outdoors. Made of lightweight yet durable 20D rip-stop nylon, it features a damage-resistant outer shell. The two-layer design and Alpinus DualTherm insulation filling guarantee effective thermal insulation with a low total weight.
Temperatures and conditions of use
Temperatures of use of the sleeping bag determined in accordance with EN 13537:
- 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 through the night without discomfort,
- T-extreme: -11 deg. C - the lowest temperature at which you can 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 characterised by good water vapour 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 insulating properties even when wet. It effectively retains heat at lower temperatures and prevents overheating at higher temperatures. 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
This model has a two-way zip made by YKK on the left-hand side. It allows for full unzipping or partial unzipping from the bottom, which improves ventilation. Thanks to the Anti Snag system, the zip does not get stuck on the fabric, and an additional lock prevents accidental unzipping while sleeping. The inside contains a small zipped pocket - perfect for small items.
Integrated hood to protect against the cold
The integrated hood provides effective protection against the cold and increases 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, when additionally compressed, 25 x 18 cm. Thanks to its low weight of 850 g, it is extremely handy and does not put too much strain on your equipment.
Set elements
The set includes a compression bag with sturdy buckles, which secures the sleeping bag during transport and protects it from dirt and damage.

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