Toasty warm.

To determine if the sleeper will be warm in this situation, we'll need to consider the sleeping bag rating and the outside temperature.

The sleeping bag rating indicates the lowest temperature at which the bag is designed to keep a person warm. In this case, the sleeping bag has a rating of +35 degrees Fahrenheit. This means that it is designed to keep the sleeper warm in temperatures above 35 degrees Fahrenheit.

The outside temperature is given as 60 degrees Fahrenheit. Since the outside temperature is higher than the sleeping bag rating, it suggests that the sleeper should feel comfortable and warm within the sleeping bag.

However, it's important to note that individual preferences for warmth can vary. Some people may find a +35 degree bag too warm for a 60-degree night, while others may feel just right. Factors such as personal metabolism, clothing worn inside the bag, and body insulation can also affect how warm or cool the person feels.

To ensure maximum comfort and warmth, it is advisable to dress appropriately for the sleeping conditions and adjust the clothing layers inside the sleeping bag accordingly. If the sleeper begins to feel too warm, they can vent the sleeping bag by partially unzipping it or by using features like a sleeping bag hood drawstring to regulate their temperature.

In summary, based on the given information, the sleeper with a +35 degree sleeping bag should be warm in 60-degree outside temperatures, but personal preference and individual factors can influence comfort levels.
