Snugpak Special Forces: first impressions

The The Snugpak Special Forces bivy sack is ultralight minimalism in neat package. The military have been using bivy sacks for decades, and service-style practical designs have plenty of advantages for the lightweight camper. Snugpak’s Special Forces sack makes full use of those virtues.


• RRP: $179 (US) / £85.00 (UK)
• Weight: 340g / 12oz
• Length: 230cm / 91in
• Width (shoulder & foot): 88cm & 65cm / 35in & 26in
• Materials: Paratex Dry
• Mouth Closure: Drawstring hood
• Features: Center-line quick-open zip, separate stuff sack
• Colors: Black / Olive / Coyote Tan

The half-length, non-locking zip makes getting in and out of the sack quick and easy, while its rustle-free Paratex Dry fabric, in blend-in colors, makes disappearing into the undergrowth easier for stealth sleepers.

Lightweight and compact, this is a sack for experienced minimalist campers whose hardcore bivying skills can upgrade its basic specifications to cope with more demanding conditions.

Bivy sacks in general can work well as weather-proof hides for wildlife watching, but the Special Forces bivy sack’s muted colors and soft non-rustling Paratex fabric make it absolutely ideal for this aspect of bushcraft. (Amazingly, even Snugpak’s Paratex sleeping bag liner can double up as a bivy sack if you’re tempted to go even more minimalist.)

The Snugpak Special Forces is one of the most compact and lightest bivy sacks I’ve tested, and that’s despite the weight of the half-length zip. The fabric is light, and the emphasis is on waterproofing more than breathability, while the dimensions are adequate rather than generous. But for the minimalist lightweight hiker this is a solid piece of kit. 

It’s light enough to take on almost any trip, including as a backup emergency shelter for day hikes. For anyone with good bushcraft skills the sack can cope with most weather conditions.

For military users the burst-out zip allows for immediate action. As a more pacific user myself, I like that it allows me to get my sleeping bag and myself into shelter quickly, and to leave the bag half open if it the weather is warm and dry.

The half-length zip also means that the sack can be used as a quick-to-set-up, sit-up hide for wildlife watching.
