I bought this for a trip to Australia for work so that I didn't have to lug along my regular sized bottles/containers. I thought the products in this selection were great, and in nice sizes so you could take them on the plane with you if you wanted to. Very very handy.
I have since purchased another set to put in my gym bag which has been great. I really like having my normal skin care available to me all the time, without having to have the full size bottles in multiple places.
I love Trilogy Products so this is a no brainer for when I travel. The products are great and it keeps my skin looking good no matter how the weather changes, though I do keep the rodehip oil with me during winter.
