Product Overview

The SF Bivvi Bag WGTE is designed to act as a protective outer shell for your sleeping bag, improving weather resistance while maintaining excellent pack efficiency. It is not a freestanding shelter, but a sleeping bag cover intended to be used directly over your sleep system.

Constructed from Paratex Dry fabric, the bivvi actively moves moisture away from the sleeping system at a rate of up to 7.5 litres per square metre per 24 hours. This helps keep you warm, dry and comfortable during prolonged use in wet or windy conditions.

The centre half-zip design allows quick entry and exit, making it particularly well suited to adventure racing, emergency harbour areas and situations where rapid movement is required. It can be carried permanently in a pack as a low-bulk contingency layer.

Please note: Snugpak bivvi bags feature a solid waterproof coating. Although breathable, they must not be fully sealed, as sufficient air cannot pass through the fabric to sustain breathing.

Intended Uses

• Adventure Racing – Lightweight weather protection for fast-moving events.
• Bushcraft & Survival – Emergency sleeping bag cover in poor conditions.
• Military & Field Use – Harbour area protection for sleeping systems.
