The Trail Kids Sleeping Bag in a mummy shape is designed to cater to young campers aged between 4 to 12 years, with a maximum height of 5ft 5in. Its snug mummy design, complete with an elasticated hood, offers excellent warmth and insulation, making it suitable for three-season camping from early spring to late autumn. The sleeping bag is made from durable water-repellent polyester and filled with 300gsm hollowfibre, providing a comfortable experience in temperatures ranging from -5˚C to 15˚C.

Portability is a strong suit of this product, as it comes with a lightweight rucksack-style carry bag, allowing kids to easily transport it themselves. This feature is particularly beneficial for family camping trips or sleepovers. Weighing only 1.1 kg, the rucksack is manageable for young users, enhancing their independence.

The dual-zipper design facilitates temperature regulation, which is valuable for comfort during unpredictable weather. An added internal pocket offers handy storage for small items like a torch or snacks, which can be a fun feature for kids. However, the sleeping bag might not be suitable for harsher winter conditions due to its three-season rating. While the elasticated hood is designed for safety, some children might prefer the feeling of a traditional drawcord hood for more security. Additionally, the polyester and down material blend might not appeal to those seeking fully natural materials.

This sleeping bag is an excellent choice for parents looking to introduce their children to the world of camping. Its practical features, combined with its appealing design and ease of use, make it a strong contender in the kids-sleeping-bags category, particularly for moderate climates and settings.

The materials used are polyester both inside and out, ensuring a soft and cozy feel while being waterproof and breathable, which helps keep kids warm and dry even if conditions get damp.

It also comes in bright pink, which many kids might find fun and appealing. One handy feature is the backpack-style carry bag with compression straps, making it easy for kids and parents to transport and store the sleeping bag when hiking or camping.

Buying Guide for the Best Kids Sleeping Bags

Choosing the right sleeping bag for kids is crucial to ensure they have a comfortable and warm sleep during camping trips or sleepovers. Kids' sleeping bags come in various shapes, sizes, and materials, and selecting the right one involves considering factors like temperature rating, size, material, and additional features. It's important to match the sleeping bag to the child's needs and the environment they'll be using it in. This guide will help you understand the key specifications to look for when choosing a kids' sleeping bag.
Temperature RatingThe temperature rating of a sleeping bag indicates the lowest temperature at which the bag will keep the average sleeper warm. This is crucial for ensuring your child stays comfortable and safe in different weather conditions. Sleeping bags are generally categorized into summer, three-season, and winter bags. Summer bags are suitable for warm weather, three-season bags are versatile for spring, summer, and fall, and winter bags are designed for cold conditions. Consider the typical weather conditions of your camping trips or sleepovers to choose the right temperature rating for your child's sleeping bag.
SizeSize is an important factor because a sleeping bag that is too large or too small can affect comfort and warmth. Kids' sleeping bags come in various sizes, often categorized by age or height. It's important to choose a size that fits your child well, allowing them to move comfortably without excess space that can lead to heat loss. Measure your child's height and compare it to the sleeping bag dimensions to ensure a snug fit that will keep them warm and cozy.
MaterialThe material of a sleeping bag affects its warmth, weight, and durability. Common materials include synthetic fibers and down. Synthetic sleeping bags are generally more affordable, dry quickly, and insulate well even when wet, making them a good choice for damp conditions. Down sleeping bags are lightweight and offer excellent warmth but can be more expensive and less effective when wet. Consider the environment and conditions your child will be using the sleeping bag in to decide which material is best suited for their needs.
ShapeSleeping bags come in different shapes, such as rectangular, mummy, and semi-rectangular. Rectangular bags offer more space and comfort, ideal for kids who move around a lot in their sleep. Mummy bags are more form-fitting and provide better insulation, suitable for colder conditions. Semi-rectangular bags offer a balance between space and warmth. Consider your child's sleeping habits and the expected weather conditions to choose the shape that will provide the best comfort and warmth.
Additional FeaturesAdditional features can enhance the functionality and comfort of a sleeping bag. Features like hoods, draft collars, and zippers can improve warmth and ease of use. Some sleeping bags come with pockets for storing small items or are designed to be easily packable. Consider what features might be beneficial for your child's comfort and convenience, such as a hood for extra warmth or a pocket for storing a flashlight or favorite toy.
