The only bivvy we tested that didn't leave Ryan wet with his own sweat. That alone makes the SOL Escape our top emergency bivvy. It scores 87 out of 100 and ranks #1 in our best emergency bivvy guide as our best overall emergency bivvy.
Best Overall Emergency Bivvy
SOL Escape Bivvy
- Weight (our scale): 8.5 oz
- Packed size: about a water bottle

Pros
- Virtually zero condensation: it breathes
- Added about 10 to 12°F to his sleep system
- Windproof
- Side zip and hood drawstring
Cons
- Heaviest and bulkiest bivvy here at 8.5 oz
- Reflects 70% of body heat, less than the foil types
In the Frank Church Wilderness
Ryan took the Escape on an early November hunting trip in the Frank Church Wilderness, Idaho, and used it over his sleeping bag inside a floorless tarp shelter at 22°F.
His down bag stayed bone dry. The fabric let sweat out as vapor while reflecting body heat back, and he reckons it added 10 to 12°F to his sleep system. No draft got through the outer fabric.
It survived rough cot edges, boots and pine needles without a puncture. The side zip and hood drawstring made it the easiest bivvy here to get in and out of, and it scored 9.5 out of 10 for ease of use.
Where It Asks Something of You
Space and weight. At 8.5 oz and about the size of a water bottle, it's nearly twice the weight of the foil bivvies and won't live in a jacket pocket.
It reflects 70% of body heat, where the foil types claim 90%. Ryan thinks the dry night is worth more than the difference.
Spec Sheet vs Our Test
Reflects 70% of body heat. SOL says the breathable fabric reflects 70% of body heat. That's less than the 90% foil bivvies claim, but foil traps sweat. At 22°F, Ryan stayed dry all night, and a dry sleeping bag is a warm one.
Reduces condensation. SOL claims its fabric blocks rain, snow and wind while reducing condensation. Ryan found virtually none: his down bag was bone dry in the morning, which none of the foil bivvies managed.
Quiet and tear-resistant. SOL says it's quiet and resists tears. Ryan used it over a sleeping bag on a cot, the hardest test of fabric here, and it took cot edges, boots and pine needles without a puncture. For a bivvy you might use for many nights rather than once, that toughness matters.
Should You Buy the SOL Escape Bivvy?
Yes. If you might spend a whole night in an emergency bivvy, or want one that doubles as a sleeping bag cover, this is the one. Ryan carries two in his own car kit.
If it has to fit in a pocket, carry the SOL Emergency Bivvy, at less than half the weight, and accept a damp night.
