Review: una certezza - l'ho provato ma a temperature più alte di quanto previsto, ma tiene più caldo di quanto si possa pensare. è molto leggero e appare sottilissimo, ma la fibra cava con cui è fatto lo rende molto performante. Sea To Summit è una certezza, il prodotto si paga, ma la qualità è eccellente. oltretutto è molto morbido, non dà fastidio sulla pelle e non irrita le parti intime, cosa molto importante per me che dormo nudo
Review: Hafif ve küçük boyutlu - Hafif, yer kaplamıyor ve işini görecek gibi duruyor. Sea To Summit kalitesi..

### ⭐⭐⭐⭐⭐ Hafif ve küçük boyutlu
*by A***R on 12 May 2024*

Hafif, yer kaplamıyor ve işini görecek gibi duruyor. Sea To Summit kalitesi..

### ⭐⭐⭐ Sensación Agridulce
*by A***O on 16 February 2021*

Por el precio me esperaba más, no aporta 11°C ni por asomo, quizás 5 pero es hablar mucho. Es ligero, da más comodidad en el saco y facilita el aseo del saco haciendo que sufra menos con sudor y aceites corporales. Yo lo voy a usar mucho con sacos ligeros, pero el precio es excesivo. Si costara 15-20€ sería perfecto. Por el doble es una sábana saco algo elástica muy subida de precio
