The MalloMe Sleeping Bag is designed as a lightweight and versatile option, ideal for warmer weather camping from spring through fall. It offers a comfortable temperature range from 50°F to 80°F, making it suitable for mild summer nights and slightly cooler conditions. Weighing about 3 pounds (1.32 kg), it’s light enough for backpacking and easy to carry with its included compression sack. The rectangular shape provides ample space for a single person up to 6 feet tall, which is beneficial if you prefer more room to move around while sleeping.

The synthetic insulation is effective for warmth while still being compressible and easy to maintain. Its polyester outer shell uses a waterproof hex-tech design, helping keep you dry in damp conditions and allowing for simple cleaning—either wiping off dirt or machine washing. The double-sided zippers and adjustable drawstrings add practical features for comfort and ease of use. However, this sleeping bag is best for temperatures not much lower than 50°F, so it might not be suitable for colder nights or winter camping.

Because of its rectangular shape, it may not retain heat as efficiently as mummy-shaped bags designed for colder weather. For those seeking a reliable, lightweight sleeping bag for casual camping in mild climates or summer backpacking trips, the MalloMe bag provides good durability and comfort.

The sleeping bag is impressively lightweight and compresses down to a very manageable size, making it easy to carry on hiking trips.

This sleeping bag is designed with summertime and mild weather camping in mind, fitting adults up to about 5 feet 11 inches tall. It has a temperature rating of 10 to 20 degrees Celsius (50-68°F), making it suitable for comfortable use in warmer seasons but not for cold weather. The bag is filled with hollow cotton insulation, which offers moderate warmth but is less efficient than down or synthetic fills in colder conditions. It features a semi-rectangular shape that balances comfort with lightweight packability.

Weighing just 3.3 pounds, it’s light enough to carry on hiking or backpacking trips where every ounce counts. The packed size is relatively compact, and it comes with a compression bag to make storage and transport easier. The outer shell is made of 190T nylon with a waterproof and breathable coating, helping keep you dry from light moisture while remaining comfortable. The design includes a drawstring hood to keep your head warm and a foot zipper to adjust ventilation, which is handy for changing temperatures. The materials feel soft and skin-friendly, and the bag cleans easily, which is great for outdoor use.

The cotton filling, while warm, can absorb moisture and take longer to dry compared to synthetic options, which might be a consideration if you expect damp conditions. Also, the temperature range targets lower summer and spring nights rather than true hot summer or cold weather camping. The size fits most adults under 6 feet, which might be tight for taller users. This sleeping bag is a solid choice for casual campers, summer hikers, or anyone needing a lightweight, waterproof summer sleeping bag without breaking the bank. It's especially good for those who want an easy-to-maintain, warm-enough bag for mild weather and appreciate the convenience of a compact, portable design.

Buying Guide for the Best Lightweight Summer Sleeping Bag

Choosing the right lightweight summer sleeping bag can make a significant difference in your outdoor experience. The right sleeping bag will keep you comfortable and well-rested, without adding unnecessary weight to your pack. When selecting a sleeping bag, consider the climate you'll be in, your personal comfort preferences, and the type of activities you'll be doing. Here are some key specifications to help you make an informed decision.
Temperature RatingThe temperature rating indicates the lowest temperature at which the sleeping bag will keep you warm. This is crucial because it ensures you stay comfortable during cool summer nights. Summer sleeping bags typically have a temperature rating between 35°F and 50°F. If you tend to get cold easily, opt for a bag with a lower temperature rating. Conversely, if you sleep warm or will be in a very warm climate, a higher temperature rating will suffice.
WeightWeight is a critical factor, especially for backpackers and hikers who need to carry their gear over long distances. Lightweight summer sleeping bags usually weigh between 1 to 3 pounds. If you prioritize a lighter pack, aim for a sleeping bag closer to 1 pound. However, if you don't mind a bit of extra weight for added comfort or warmth, a 2 to 3-pound bag might be more suitable.
Insulation TypeThe insulation type affects the sleeping bag's warmth, weight, and compressibility. There are two main types: down and synthetic. Down insulation is lightweight, highly compressible, and offers excellent warmth, but it can be more expensive and loses insulating properties when wet. Synthetic insulation is more affordable, dries quickly, and retains warmth even when damp, but it is bulkier and heavier. Choose down if you need a compact and lightweight option and synthetic if you expect wet conditions or are on a tighter budget.
ShapeSleeping bags come in various shapes, including mummy, rectangular, and semi-rectangular. Mummy bags are snug and efficient at retaining heat, making them ideal for cooler summer nights. Rectangular bags offer more room to move and are better for warmer conditions. Semi-rectangular bags strike a balance between warmth and space. Consider how much room you need to sleep comfortably and the typical temperatures you'll encounter when choosing the shape.
Packed SizePacked size refers to how small the sleeping bag can be compressed for storage and transport. This is important for saving space in your backpack. Lightweight summer sleeping bags generally have a smaller packed size, making them easier to carry. If space is a premium in your pack, look for a sleeping bag with a compact packed size. However, if you have more room or are car camping, packed size may be less of a concern.
Shell MaterialThe shell material affects the sleeping bag's durability, weight, and water resistance. Common materials include nylon and polyester. Nylon is lightweight, durable, and often treated for water resistance, making it a good choice for most conditions. Polyester is also durable and can be more affordable but may not be as lightweight. Choose a shell material based on the expected conditions and your preference for weight and durability.
