SKU: kingcamp-snowflake-400-single-sleeping-bag-3-season-flannel-slee
Overview
Built for colder 3-season trips, this sleeping bag is aimed at campers who want dependable warmth without giving up a softer sleep surface. The cotton flannel lining and 400g/m² polyester loose fiber fill make it well suited to spring, fall, and milder winter nights, while the zip-together design adds flexibility for couples or family camping. It also works beyond the campsite, since it fully unzips for use as a blanket or padded layer for guests, picnics, or backyard sleepouts. For hunters and outdoor travelers who value comfort and adaptable use, it offers a practical option for cool-weather overnights.

Considerations & Trade-offs
- At 5.1 lbs, it is not a lightweight option for hikers trying to minimize pack weight.
- The 39°F comfort rating and 32°F limit suggest it is better suited to cold 3-season use than true deep-winter conditions.
- The zip-together feature requires a matching left-zip and right-zip setup, so it is most useful when planning ahead for paired use.
- The soft cotton flannel lining adds comfort, but it may feel warmer and less airy than a more minimal synthetic lining in milder weather.
