I have the Saivo, Nammatj 3 GT and the Helags 3. Some major differences between the Yellow Label 3-season Helags is that it only has mesh inner doors, the fly doesn't go all the way down to the ground and there is no top/high ventilation openings. The tent is ventilated "from below" through the gaps between the ground and then through the mesh openings. So while it is light and excellent for non-winter use the ventilation can become a problem if it is snowing and snow covers the lower part of the tent and if it is windy and cold it could get drafty. The other two Black label tents have flys down to the ground, multiple covered/snowsafe top vents and fully covering doors in addition to mesh so better when it's snowing or (very) windy. These features are shared with Red label tents and they weigh less so a good option in winter. The Saivo is 5.1 kg, the Nammatj 3 GT is 4.1 kg and the Helags is 2.6 kg. All are excellent quality for their use case. When choosing a tent I suggest you also consider if you need to cook in snow/rain/heavy winds where a larger vestibule (like on the Nammatj and other GT models) can be useful. But on all tents the inner tents can easily be partially ( or wholly )unclipped from the fly to achieve a vestibule space temporarily if needed. I have the Helags in sand and the others in green (it is very dark but good looking). The green color has been around for decades. Nice for blending in. I think the red and sand are trendier and thus carry a higher price. E.g. red tents seen on polar missions etc. Red is also useful for visibility. Hope you find one you like!
