## Description

The **Thermarest Hyperion 32F/0C long sleeping bag** combines all the performance you expect from a down bag when seeking **warmth**, **compactness** and **low weight**. The Hyperion 0 sleeping bag is an ally for hikers for whom every gram counts.

## Unrivalled light weight and compactness

The Thermarest Hyperion 32F/0C long sleeping bag is the **lightest sleeping bag in our 0°C to +5°C range**. Weighing just 500 grams, it is the featherweight of its class.
Its goose down fill with **900 Cuin fill power** also delivers outstanding quality, offering the **highest fill power** available on the market.

Once released from its compression sack, your Hyperion sleeping bag will feel like your duvet at home, providing excellent sleeping comfort.
The materials allow the bag to be compressed fully without damage. Rolled up, it becomes tiny and fits easily into the bottom of your backpack.

## Outstanding thermal and technical performance

Not only does 900 Cuin goose down make the sleeping bag **exceptionally lofty**, **ultralight** and **ultra-compact**, it also provides impressive warmth for such a lightweight bag:

- The down used in the Thermarest Hyperion 32F/0C sleeping bag is **Nikwax Hydrophobic Down**. Treated against moisture, it stays dry, absorbing 90% less moisture than conventional down and drying 3 times faster. This technology also lets the down retain its loft 60 times longer than untreated down.
- The Hyperion 32F/0C sleeping bag has **a ThermaCapture lining**, trapping and retaining body heat.
- The fill is **distributed differently by zone** to maximise warmth where the body needs it most.
- Mesh baffles maintain loft and prevent cold spots.

The down is RDS-certified (Responsible Down Standard), sourced with respect for the environment and animal welfare. The hydrophobic treatment is guaranteed free from hazardous perfluorinated compounds (PFCs).

The Hypérion 32F/0C sleeping bag features:

- Zip approximately 90 cm long with a protective flap
- Hood with drawcord adjustment
- Removable SynergyLink connectors: attach your sleeping bag to your mat for maximum comfort

It comes with a storage sack and a compression sack.

Je vais vous présenter le sac de couchage Hyperion 0 de Thermarest. C'est un sac qui mérite tous les superlatifs, puisqu'on est sur des températures de confort de +5 °C à 0 °C, donc un sac qui va
  
  [0:18](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-18) convenir pour la plupart des randonnées estivales, mais avec un volume, que vous voyez là, comprimé au maximum, qui est vraiment tout petit, et un poids de 500 grammes, qui en fait le plus léger dans cette gamme de
  
  [0:34](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-34) performances. Donc c'est un sac qui est vraiment très, très intéressant si vous voulez le confort thermique, mais tout en étant dans la chasse aux grammes et la chasse à l'encombrement. Ses performances, elles sont dues en particulier à la qualité du garnissage, je
  
  [0:51](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-51) vais vous en parler plus précisément. Alors, vous pouvez vous rendre compte déjà visuellement du gonflant du sac. En fait, on est sur un sac hyper léger, donc ça veut dire qu'il n'y a pas énormément de plumes dedans, et malgré tout, on a un super gonflant. Ça s'explique par la qualité du duvet d'oie
  
  [1:07](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-67) puisqu'on est sur un duvet 900 cuin, donc c'est vraiment le niveau de gonflant le plus élevé qu'on puisse trouver. Et en plus, le duvet fait l'objet d'un traitement Nikwax, donc c'est un traitement hydrophobe. Donc ça veut dire que ça ne craint pas autant l'humidité
  
  [1:22](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-82) que les duvets traditionnels et, du coup, ça préserve le pouvoir gonflant du duvet encore plus longtemps, même dans des conditions humides. Donc ça, ça explique vraiment la qualité de protection thermique malgré la légèreté du duvet. Ensuite, on a
  
  [1:39](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-99) les éléments de finition qui sont de très bon niveau, donc une bonne capuche bien enveloppante, avec des bourrelets autour de tête. On peut serrer vraiment, refermer, bien s'isoler complètement. Une fermeture Éclair qui fait un peu
  
  [1:56](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-116) plus d'un mètre, je dirais, à peu près un mètre de long. Comme souvent sur les sacs ultra légers, ça ne va pas jusqu'aux pieds, mais ça permet quand même de s'y glisser facilement et de se découvrir un petit peu si besoin. Et puis, globalement, une qualité de
  
  [2:11](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-131) matériaux qui est au rendez-vous. On sent que, bon, c'est un tissu doux et de bonne qualité. On a un système de cloisons qui permet d'assurer également une bonne répartition du garnissage, avec des zones plus garnies
  
  [2:26](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-146) là où il y a besoin de plus de protection, de façon à optimiser là aussi le rapport poids-protection thermique. Dernier détail intéressant : on a sous le sac deux petits cordons qui sont amovibles, donc
  
  [2:42](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-162) vous pouvez les dégager si vous n'en avez pas besoin, mais ça peut vous permettre de fixer le sac sur votre matelas, donc d'éviter de glisser pendant la nuit. Ça, ça ajoute également un petit détail
  
  [2:57](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-177) intéressant. En résumé, c'est un sac dont les caractéristiques font rêver, à la fois les performances et la qualité des finitions. Alors, c'est un investissement, donc ça se justifie à mon sens pour un usage régulier ou si vous êtes vraiment dans une optique de chasse aux grammes pour essayer d'optimiser encore votre sac.
  
  [3:14](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/3473-hyperion-32f-0c-long-sleeping-bag.html#video-OJO7JZlx53M-t-194) Il existe également dans une version plus chaude qui s'appelle l'Hyperion -6, un petit peu plus lourd, mais qui vous permet d'aller jusqu'à des températures négatives, donc ça peut être également une solution intéressante si vous hésitez en termes de protection thermique. Vous
