Key Features

Multi-Season Use:
Designed to provide effective insulation and comfort across three seasons, the Trekker Envelope Sleeping Bag is suitable for spring, summer, and autumn conditions. It offers reliable thermal protection for various outdoor environments.

Thermal Hollow Fibre Insulation:
The 150gsm hollow fibre filling helps trap body heat effectively while allowing for breathability, making it ideal for cooler nights without overheating during warmer evenings.

Soft Comfort Lining:
The inner lining is made from a soft-touch polyester material, delivering a cozy sleeping experience that enhances comfort throughout the night.

Durable Outer Shell:
Constructed with 170T polyester, the outer layer offers durability, light moisture resistance, and easy maintenance—ideal for repeated use on campsites or in travel settings.

Generous Sizing:
With dimensions of 180cm x 75cm, the rectangular (envelope-style) shape offers ample room to move, making it especially suitable for those who prefer a less restrictive sleeping experience than mummy-style bags.

Efficient Temperature Rating:

Upper Limit (20°C): Appropriate for use in warm weather with ventilation.

Comfort (12°C): Ideal range for restful sleep during moderate nights.

Lower Limit (2°C): Suitable for colder conditions when paired with warm sleepwear or additional layers.

Compact and Lightweight:
Weighing approximately 900g, the sleeping bag packs down into a manageable size, making it easy to carry in a backpack or camping kit without adding excess bulk.


Usage Tips

Optimize for Cooler Nights:
For temperatures approaching the lower limit (2°C), use thermal underlayers or a sleeping mat to enhance insulation.

Air Out Between Uses:
Unpack and air the sleeping bag after each use to maintain freshness and prolong the lifespan of the insulation.

Use a Sleeping Bag Liner:
A liner can provide added warmth, improve hygiene, and reduce the need for frequent washing.


Ideal For

Weekend campers and caravaners

Festival-goers seeking affordable comfort

Youth group or scout trips

Spring and summer backpacking excursions

Indoor overnight stays or guest bedding
