### ⭐⭐⭐⭐⭐ 







  
  
    Excellent warmth to weight ratio
  

*by R***O on Reviewed in the United States on 3 November 2024*

This bag comes folded in a large cube-shaped zippered bag, preserving its fluffiness.  It includes a stuff sack that is the same size of a typical warm-weather thin bag.  It’s not much bigger than my poly-fill camp blankets that are good to maybe 50°.  Once unstuffed, this appears a bit wrinkly, but it fluffs out to an impressive thickness.  It’s a good 4” thick when fluffed up, there’s a lot of air gap between me and the outside while in this bag.  The side zipper is easy to operate with pulls on either side. Pulling both pulls at once makes for a clean zip. No catching on the sides.  There is a flap inside the bag that overlaps the zipper.  Lifting this provides a controlled bit of ventilation if the bag gets too warn.  The hood is large and has a drawstring to constrict the opening.  I am able to position this so the exposed part of my face is a few inches below the wind, it is a large hood.I got the XL length, being right at the edge of the sizes. I like the extra room at my feet, and it allows me to scoot down and bunch up the top a bit as a pillow.  There’s a lot of coverage at the head, which I like.Extremely lightweight for the amount of warmth it provides.  Fluffs out an impressive amount, stuffs small enough to fit in my 55L pack.The material is thin enough to see the fill thru the yellow parts.  It feels like ultralight hammock fabric.  Soft for a synthetic.No negatives to this bag, aside from being expensive; it’s a winning design and top quality.

    Lightweight, compact, toasty
  

*by T***Y on Reviewed in the United States on 30 October 2024*

When you go ultralight, you will have to sacrifice durability. I understand that as a non-negotiable regardless of what a product description may state. That said I've taken care of the bag, and it's taken care of me. I've got the 28°F and the 5°F. I haven't had the chance to test at 5°, however I have been near 25° and I was very warm. I would guess it would be good for as low as 5° with some layers. Love it

    Pensar antes de comprar
  
  

*by F***A on Reviewed in Brazil on 3 July 2024*

PONTO POSITIVO: O saco é realmente leve, isso é o maior ponto positivo do produto, macio, aquece e é super compacto na hora de colocar na bolsa pra transporte.PONTO NEGATIVO: com o uso ele vai soltando algumas plumas, após acordar em todas as vezes que utilizei, achei plumas na minha roupa, o zíper precisa de cuidado para abrir e fechar, caso contrário ele pode pegar no tecido. A cor clara é outra questão, se não tomar cuidado vai sujar muito rápido.Então pense nisso antes de comprar, se você pretende comprar um saco de dormir que dure a vida toda, talvez esse não seja o caso, acredito que ele vá durar por uns bons anos ainda mas a longo prazo não sei se vai reter tanto o calor devido a essa perca de pluma com o uso.Se optar por comprar, seja cuidadoso com o zíper, siga as instruções de armazenamento da marca para ajudar a prolongar a vida útil do saco e  esteja ciente de que vai perder pluma e isso pode gerar pontos frio no saco de dormir e tem a questão da cor que é clara e suja fácil.Quanto ao tamanho, não recomendaria ele para uma pessoa maior de 180cm.
