Size
Size Chart
Avec juste 570 g (1 lb 4 oz), l’Hypérion vous permet de braver le froid et de mieux vous reposer quand vous passez la nuit dans les montagnes.
  • Poids-plume: un des sacs les plus légers de sa catégorie, l’Hyperion est devenu une référence pour l’équipement de plein air haute performance.
  • Duvet hydrophobe de gonflant 900 Nikwax Hydrophobic Down™: reste plus sec et maintient son gonflant 60 fois plus longtemps que du duvet non traité.
  • Volume extrêmement réduit une fois enroulé: les matériaux légers et la précision de la fabrication permettent de le replier pour un volume encore plus réduit.
  • Cloisonnement intérieur: cloisons en maille mesh pour maximiser le gonflant et minimiser les points froids dans les zones-clés.
  • Confort: sa forme ergonomique et une fermeture à glissière plus longue lui permettent de mieux s’adapter à votre morphologie que d’autres sacs ultralégers.
  • Connecteurs SynergyLink™: connexion au matelas pour une efficacité et un confort optimisés (amovibles pour plus de polyvalence).
  • Isolation par zone: maximise la chaleur et optimise le poids en répartissant précisément le garnissage là où il est le plus utile (70 % sur le haut et sur les côtés, avec 30 % sur le dessous).
  • Issu de l’élevage responsable selon les normes Responsible Down Standard : garantie que les oiseaux dont provient le duvet sont traités sans cruauté.

Reviews

Perfect sleeping bag!

"Is a Life changing! I used it every time i go on trekking escape. Ultra lite and compact, that sleeping bag change the game. Its a reel confortable 0 degres."

— raphael b. (5/5)

Great bag. Used it so

"Great bag. Used it so many times under so many conditions and has been good to minus five comfortably."

— Dave M. (5/5)

Lightweight

"Amazing lightweight and warm. Zipper only goes down hallway of the bag could be a deciding factor for some."

— Dillon L. (5/5)

Surprisingly warm for weight. Bring it back! Love this bag.

"I was surprised how warm this bag was after I first pulled it out. Frankly, it felt flimsy. But I figured I'd try it in a *35 overnight and see if I could find a way to shave the weight of my monster bag. Yes you have wear a base layer when you sleep but this kept me toasty and was really an all around game changer for me. The 900 fill is the secret I think. Would love to buy a short one for my daughter but they're all sold out. Bring it back!"

— Richard A. (5/5)

High Quality light weight material

"High Quality light weight material that packs very small"

— Parker B. (5/5)

Great bag, too short

"At 6' 4" I thought I would fit comfortably in this bag and while I just managed to fit my head in, it felt very tight and uncomfortable. I used this bag during my PCT thru hike and most nights i just slept with the hood off since it was more comfortable that way. When the temps got down I was forced to use the hood which made it quite tight. Love the hydrophobic down! Super light! The stuff sack that comes with the bag isn't the greatest, I used another compression sack."

— Chris (4/5)

Awesome!

"Light and super toasty!"

— John D. (5/5)

A Great Quilt Alternative

"I use this on overnight hiking trips and sheep hunting. I compare it to my Enlightened Revelation Quilt. Both are great ultralight sleep systems that have concessions. Bag is a bit snug fitting, but it's enough space to be comfortable. The snug fit means there is no dead air inside the bag with you. Great storage options, super light, packs very small (I'd say x1.5 my 1L Nalgene). Very well built, material is soft. Order came quickly and price was fair. Good job on this bag Thermarest."

— Conner L. (5/5)

Light for degree rating.

"The 3/4 zipper takes getting used to. Warmer weather makes it tough. It is a narrower fit but is right for my body. Lightest bag in this class."

— Kevin C. (4/5)

A number of years ago

"A number of years ago I purchased a Hyperion 0 deg bag to replace a worn out old favorite. The Hyperion quickly turned into my new go to bag. Warm, very light, and quite roomy. It also became a favorite of my wife's for bike packing. This year I decided to get the Hyperion 20 for warmer trips. Only drawback is securing it from my wife who currently has it on a pack raft trip! Cascade Designs truly nailed it with Hyperion line up!"

— Ron C. (5/5)
