Waterproof Bivvy Bag for Mummy Sleeping Bags

  • Light & breathable Tyvek material
  • Protection from normal tent condensation
  • Protects sleeping bag from dirt
  • Provides additional insulation
  • Ideal for all-weather camping
  • FREE DELIVERY AVAILABLE OVER £60



Stay warm and dry in any weather with the 3F UL Gear Tyvek Bivvy Bag! This lightweight bivvy has been designed to
provide maximum protection and insulation for your mummy or quilt sleeping bags.

Made from the durable Tyvek material, it offers breathability while keeping you dry from normal tent condensation.

The Bivvy Bag also acts as an outer shield for your sleeping bag inside, keeping it clean and free from dirt, especially when camping in wet or muddy conditions.

It’ll also keep you warmer and more snug through those chillier nights, creating additional insulation and trapping heat. 

It works well for all-weather camping, but we do recommend using a shelter in rainy conditions, as the light waterproofing may not be enough for heavy downpours. In which case, you should opt for a more heavy-duty bivvy, like the Bushmen HIDEOUT Thermo.

Choose between two options – with or without a zip closure for easy access. The zip option allows convenient entry and exit, while the zipless version reduces weight.

FAQs

Why is Tyvek a Good Material for a Bivvy Bag?

Tyvek is an excellent material for a bivvy bag because it is lightweight, waterproof, and breathable. It offers protection against moisture and dirt while allowing vapour to escape, ensuring comfort and dryness during outdoor adventures in all weather conditions.

What Colour is the Tyvek Bivvy?

The Tyvek Bivvy Bag is a white colour, which makes it a popular choice for camping in mountainous and snowy regions.

Should I Choose the Tyvek Bivvy With or Without a Zip?

This all depends on personal preference and intended use. The zipped model will keep you a little more protected from the elements and may be a better option for colder weather conditions.

However, the non-zip model is more lightweight and compact, making it ideal for backpacking and hiking trips.

What is a Bivvy Bag Used For?

A bivvy bag is used to protect your sleeping bag from moisture, dirt, and condensation when camping. It provides additional insulation, ensuring a warm and dry sleep in various weather conditions, making it essential for outdoor enthusiasts.

How Do You Use a Bivvy Bag?

To use a bivvy bag, simply slide your sleeping bag inside it, ensuring the head opening aligns with your head space. For zip options, unzip while entering or exiting, and adjust the bag position to maximise insulation and protection.
