Just ran the Welsh 3 peaks using the responsive 15L pack. Very comfortable and would definitely recommend it 👍

Bag seems really small for 15l. I cannot put my phone in the pocket. In the back it does expand, but seems clearly smaller than other Brands. It is an amazing bagback, but not for 15l. I do not see how i can fit my waterbag, food and clothes in the back. In the side i can barely put few gels. For the sticks in the back, the elastics tend to open alone. At the front the elastics of the sticks are undoing alone.

Très bonne ergonomie, beau volume de rangement, et fit très bien, très agréable à porter. 2 points à améliorer: pas se petite poche de rangement spécifique pour la couverture de survie, et surtout les poches arrières latérales vaillent un peu trop, si on met des gels dedans, ils risquent de s'échapper.
