Well I just finished 6 day camping trip with this new one and I can say that slept through the night. It was great feeling waking up to daylight instead of waking up every hour through night because of the low temperature. Another plus was the leg room inside. I almost felt like I was on a bed. As a side sleeper, I was able to use the fluffiness as lumbar support. Lastly, it is much lighter than my former one so it takes up less space. Overall, happy with my purchase. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/156246408-big-agnes-blackburn-ul-0-850-downtek-sleeping-bag](https://www.desertcart.tn/products/156246408-big-agnes-blackburn-ul-0-850-downtek-sleeping-bag) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
