    Guide's Edition Synapse 25
    Rated 5 out of 5 stars
    I was drooling for a year before being able to buy it, I drool over each times I take it

    I got mine in 2018 (fall)

    I was drooling over for a year before being able to buy it, I drool over each times I take it

    I fell in love with the old fashioned hiking look & earthy colors (so dreamy) ;

    I fell in love with added modularity: Ice Axe Loop and Accessory Strap Holders system increases its potential so much :

    - I could carry a lacy sunshade thanks to the Ice Axe Loop + centered Diamond Strap Holder ;

    - I can tie a light camping tent thanks to the bottom straps sytem ;

    *** I was already interest in the standard version of the bag (I made a review on Synapse 25 page) ***
