Warm-weather sleeping bags still need more thought than picking the lightest model. Inland nights can cool quickly, humid coastal conditions make moisture management important, and an exposed campsite can feel much colder than the forecast suggests.
The Carinthia Eagle is the compact option in the current range. The Tropen is designed around warm-weather use and offers another useful reference point. The Defence 1 is worth comparing when you want a light bag with a little more margin.
Use the comfort rating as your main temperature guide. Extreme ratings describe a survival limit under defined test conditions; they are not a sensible target for routine sleep. Your mat, clothing, shelter, metabolism and fatigue will change the result.
Ventilation matters in heat. A zip that can be opened from the foot end, enough room to move and the ability to use the bag loosely can be more useful than extra insulation. In humid country, air the bag each morning and keep it out of a waterproof stuff sack when it is not being carried.
Packed weight is only one part of the decision. Check length, shoulder room and how the bag fits with your mat and shelter. A good warm-weather bag should disappear into the load during the day and still cover the coolest realistic night of the trip.
