## Description

The **Thermarest Boost 650 20F/-6C Long sleeping bag** is specially designed for taller people seeking exceptional thermal insulation. Its **adaptable design** adjusts easily to **temperature changes**, with optimum comfort from its PFAS-free **hydrophobic down** fill.

Ideal for **three-season hiking**, it particularly suits those moving between cool and milder conditions.

## An adaptable sleeping bag with exceptional thermal protection

The Thermarest Boost 650 20F/-6C Long sleeping bag combines thermal protection and comfort:

- Its **semi-rectangular** design provides excellent freedom of movement and **converts** into a **mummy bag** for greater warmth when temperatures drop. **WarmZip™** technology lets you **adjust your comfort** using the central zip, reducing interior space and bringing the fill closer to your body to **increase thermal insulation**.
- **Hydrophobic down** fill, **RDS**-certified and **PFAS**-free, is strategically distributed in key areas through optimised baffling that eliminates cold spots. It stays dry and retains excellent loft.
- To retain warmth, **draught tubes and collars** run along the **zips** and around the **shoulders**.

## Practical sleeping bag features

The boost 650 20F / -6C Long has **2 multi-purpose openings** on the front for **putting your arms out**. Handle objects, read or adjust the WarmZip system without uncovering yourself. These openings also provide ventilation.

A **two-way zip** opens the sleeping bag from **head to foot** for even greater comfort and versatility. You can uncover **just your feet** or open it fully on mild summer nights.

An internal **pocket** holds your personal belongings.

Storage sack and compression sack included.

**Other features**

- Outer fabric: 100% recycled 20D ripstop Nylon with PFAS-free water-repellent treatment
- Inner fabric: 100% recycled soft 20D Nylon
- Fill: 650 cuin hydrophobic duck down (733 g), RDS-certified and PFAS-free

Je vais vous présenter le sac de couchage Boost 650 20F/-6C de Thermarest. Donc, c'est la version la plus chaude du Boost 650. Il existe une version un petit peu moins chaude qui s'appelle le Boost
  
  [0:22](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-22) 32. Donc, sur cette version chaude, on est sur un 0 °C en confort, -6 °C en limite de confort. Donc, sac de couchage pour les températures froides, et vous allez voir qu'il a pas mal de
  
  [0:37](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-37) particularités qui le rendent vraiment intéressant, parce qu'il va être polyvalent au niveau de la plage de température où on va être à l'aise, et également sur les conditions d'utilisation. Alors, pour commencer, les
  
  [0:53](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-53) caractéristiques générales : on a un garnissage qui est généreux, en duvet traité hydrophobe, traitement Nikwax. Donc, c'est un duvet qui est de très bonne qualité et qui, en plus, a un traitement qui va repousser l'humidité et donc préserver le gonflant du duvet.
  
  [1:09](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-69) En termes de protection thermique également, c'est maximisé : on a des bourrelets de protection le long des zips, on a une capuche rembourrée, bien enveloppante, qu'on va pouvoir resserrer fort si jamais il fait vraiment
  
  [1:25](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-85) froid. À noter donc une petite poche de rangement de téléphone à l'intérieur, également le petit bourrelet le long du cou. Donc, la protection thermique est optimisée. Maintenant, ce qui fait la particularité de ce sac et tout son
  
  [1:43](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-103) intérêt, outre la protection thermique, c'est cet aspect-là. Vous voyez que c'est un sac qui a un format sarcophage, mais on a un zip central, donc on peut l'ouvrir, et quand on l'ouvre, on le déplie et il prend un
  
  [1:58](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-118) format beaucoup plus large. Donc, double intérêt : on a plus d'espace, déjà, pour les gens qui ont besoin de bouger un peu, y compris jusqu'au niveau des pieds. Et le deuxième intérêt, c'est que quand on a un peu trop chaud, en ouvrant ce zip, eh bien, on réduit la protection thermique. Donc, on va pouvoir
  
  [2:14](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-134) être confortable sur une plage de température un peu plus large. Souvent, on l'achète pour les conditions froides, mais on va pouvoir aussi l'utiliser dans des conditions un petit peu plus clémentes. À noter aussi que les zips utilisés, ce sont des zips anti-coincement qui
  
  [2:31](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-151) sont vraiment super bien, parce que du coup, sur ce genre de tissu fin, des fois, ça pourrait bloquer. Là, ça bloque pas, ils sont très, très bien conçus. C'est la même chose ici : zip anti-coincement également. À noter que le zip est également très grand, il va jusqu'aux pieds. Donc là aussi,
  
  [2:48](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-168) on peut aérer si besoin, on peut ouvrir par les pieds. Donc là aussi, c'est un élément de confort intéressant. Et il y a un autre élément de confort assez remarquable, c'est qu'on a des sorties pour les bras ici et là.
  
  [3:05](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-185) Donc, je peux me mettre dans mon sac de couchage, bien au chaud, et sortir les bras pour bouquiner, par exemple. Voilà. Donc, c'est un sac qui est super polyvalent de ce point de vue, avec
  
  [3:20](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-200) quand même beaucoup d'équipements différents. En résumé, c'est un sac de couchage chaud, mais qui reste compact, qui va offrir plus de polyvalence que
  
  [3:36](https://www.rayonrando.com/en/sleeping-bags-5c-to-0c/12813-boost-650-20f-6c-long-sleeping-bag.html#video-VNe7HtLla-g-t-216) les sacs de couchage chauds habituels, aussi bien au niveau température que confort. Il faut savoir qu'il existe en deux tailles. Là, je vous ai montré le Regular. Il y a une grande taille également, que vous retrouvez sur le site. Donc, vous retrouvez l'ensemble des modèles sur rayonrando.com.

**How does it compare with the Boost 650 32F/0C Long?**

**How do you adjust it for the temperature?**

This Boost 650 20F/-6C Long adjusts in two ways: the central WarmZip fastening tightens it into a mummy shape in cold weather, while the head-to-foot two-way zip lets you uncover just your feet or open it fully on mild nights. Two front openings also let your arms out. What time of year will you use it?
