A sleeping bag that is 15º F should usually be adequate during the shoulder seasons, which are spring to early summer and late summer to fall. An [expedition" level (–15º or –20º F) sleeping bag will keep you warm on those infrequently extremely cold winter nights. A sleeping bag with a temperature of 0º will typically be the most comfortable option.
Grams per Square Meter is what GSM stands for. Therefore, there is greater weight per square meter the higher the number. This keeps you warmer by using extra material, stuffing, etc. Therefore, you should be warmer if your sleeping bag has a higher GSM rating.
Are sleeping bags therefore waterproof? The majority of sleeping bags are not waterproof, therefore the quick answer is no. However, they typically have tightly woven "face" fabrics on the outside of the bag that are treated with long-lasting water-repellent (DWR) finishes, making them water-resistant.
Seek Out: Aim for the lightest sleeping bag that still maintains adequate warmth for a comfortable night's sleep.

with ulation. Another important element in determining comfort is the material used in a sleeping bag. It is a popular choice because of the outstanding warmth-to-weight ratio of down in ulation. But synthetic inulation is still a viable alternative, particularly in wet environments.
A perfect fit is essential to the warmth, comfort, and overall effectiveness of your sleeping bag, in addition to its EN Temperature Ratings. An overly large bag will allow air to flow around and out of it, wasting heat; an undersized bag will compress the insulation, lessening its efficiency.
A 15-degree hiking sleeping bag will keep your body warm enough to survive at temperatures about 15°F, with individual fill power (FP) of 650 or 800. A 15-degree bag should be plenty to keep you warm and safe on chilly fall and spring evenings if you're not into winter camping and hiking.
