The Terra Incognita Siesta is a 3-season synthetic camping sleeping bag offered in four warmth ratings - 100, 200, 300, and 400 - so you can match insulation to your climate rather than overbuying. The core Siesta model carries a comfort rating around +7 C (44.6 F) with a lower limit near -4 C (24.8 F), packs to 17 x 29 cm (6.7 x 11.4 in), and weighs from just 0.83 kg (1.83 lbs), making it an easy all-rounder for spring-through-autumn camping.
Built by Terra Incognita, a European outdoor brand with more than 18 years of expedition experience and its own gear production, the Siesta line uses HollowCore 7 synthetic fill that keeps loft even in damp conditions and dries quickly - a practical advantage over down for unpredictable camping weather.
Which Siesta warmth level should you pick?
The number in each model name signals its warmth: the Siesta 100 is a light summer bag, the 200 and 300 handle typical spring and autumn nights, and the 400 pushes into cold-weather territory that reaches toward -23 C in the warmest build. Pick the rating that matches the coldest nights you expect, then add a sleeping pad underneath, since ground insulation is what determines real-world warmth as much as the bag itself.
What fabric is the Siesta sleeping bag made from?
The shell is a 210T polyester diamond ripstop that shrugs off snags and light abrasion, while the 280T micro-polyester lining feels soft against skin and wicks moisture. Inside, HollowCore 7 fibers are graded by model, with insulation weights building from the 100 up to the 400. Because the fill is synthetic, it holds warmth even when humidity or condensation would flatten a down bag.
What features make the Siesta easy to use at night?
The Glow Zip pull catches ambient light so the zipper is easy to locate on a black night, and the anti-draft collar on the 200 and larger models traps the warm air you generate around your shoulders. Choosing a left or right zip lets you pair two Siesta bags into a single double sleeping surface, a useful option for couples sharing a tent.

Questions & answers
Siesta FAQ
What temperature is the Siesta sleeping bag rated for?
The core Siesta is rated to a comfort temperature around +7 C (44.6 F) with a lower limit near -4 C (24.8 F). Across the full range, the four models cover roughly +24 C down to -23 C, so you choose the model that matches your coldest expected nights.
Is the Siesta a good winter sleeping bag?
The warmest models in the Siesta range extend toward -23 C, which reaches into winter conditions, while the core and lighter versions are best treated as 3-season bags. For deep winter, pick the highest warmth rating and pair it with an insulated sleeping pad for full protection from the cold ground.
Can two Siesta bags zip together?
Yes, the Siesta comes in left-zip and right-zip versions specifically so that one of each can be joined into a double bag. This lets couples share a single connected sleeping space instead of using two separate bags.
Does the Siesta use down or synthetic insulation?
The Siesta uses HollowCore 7 synthetic insulation, not down. Synthetic fill keeps its loft and warmth even when damp and dries far faster than down, which makes it a more forgiving choice for humid or unpredictable camping conditions.
How much does the Siesta weigh and how small does it pack?
The Siesta starts at 0.83 kg (1.83 lbs) and packs down to about 17 x 29 cm (6.7 x 11.4 in). Weight and packed size rise slightly with the warmer models, but even the higher ratings stay manageable for camping and shorter carries.
