Product Information

Full details

The Trespass Lull 3 Season Sleeping Bag is designed for outdoor enthusiasts and weekend campers who need a reliable, versatile solution for spring, summer, and autumn trips. Its primary benefit is the efficient insulation that provides warmth in temperatures as low as -12ºC, paired with a spacious envelope shape that allows for natural movement during sleep. However, users should note that at 180cm in length, it may be too short for taller individuals, and the envelope design offers less thermal efficiency than specialized mummy-style bags in extreme cold.

Extended Product Information

FAQs

Can this bag be used in winter?

This is a 3-season bag. While it performs well down to -12ºC, it is not intended for true winter mountaineering or extreme sub-zero conditions.

What are the dimensions of the bag?

The Lull sleeping bag measures 180cm in length and 70cm in width.

Is the material waterproof?

The polyester shell is water-resistant, which helps protect against minor condensation in a tent, but it is not waterproof.

Can I zip two of these together?

Yes, the envelope design is generally compatible with another Lull bag, allowing you to create a larger sleeping space.

How do I dry the bag after washing?

Always air dry the bag flat in a well-ventilated area away from direct sunlight or high heat sources, which can damage the synthetic fill.

Troubleshooting

Bag feels cold during the night

Ensure you are using an insulated sleeping mat, as the ground pulls heat away from your body faster than the air.

Zipper sticking or catching on fabric

Slowly guide the zipper with one hand while holding the internal draft tube away from the track with your other hand.

Loss of loft/warmth after a season of use

The filling may be matted from moisture or compression. Air the bag out in a dry, ventilated area and gently shake it to redistribute the insulation.

Pros and Cons

Pros

  • Spacious envelope design allows for comfortable movement
  • Suitable for use across three distinct seasons
  • Integrated shoulder drawcord helps seal in warmth
  • Durable polyester materials stand up to regular outdoor use

Cons

  • Limited length of 180cm may be restrictive for taller users
  • Envelope shape is less thermally efficient than mummy bags in extreme cold
  • Not suitable for winter mountaineering or sub-zero expeditions

Setup, Compatibility & Care

To get the most out of your Lull sleeping bag, follow these best practices:

  1. Storage: Never store the bag compressed in its stuff sack for long periods. Store it loosely in a mesh bag or hang it up to maintain the loft of the internal filling.
  2. Cleaning: Spot clean with a damp cloth for minor dirt. If a deep clean is necessary, use a large front-loading commercial washing machine on a delicate cycle with a mild detergent designed for technical gear.
  3. Compatibility: This bag works well with most standard foam or inflatable sleeping pads. Due to its envelope design, it can be easily zipped to another compatible bag if you prefer a wider sleeping surface.
  4. Drying: Always air dry the bag completely before storing it to prevent mildew and odors.
