Hybrid 3-Season Sleeping Bag for Bikepacking

The user is looking for a versatile 3-season sleeping bag (down to 5°C) that is warm, packable, and within a 150-200€ budget. Current options like synthetic Apex are packability-challenged, while down can struggle with humidity. A hybrid sleeping bag or quilt that offers a good balance of warmth, packability, and moisture resistance would fill this gap. Additionally, a focus on repairability (as seen with the local GramXpert option) or a dedicated, efficient compression solution for synthetic insulation could be a valuable product.
