I bought these for skiing and also a spare which husband or daughter can also use. I finally got to use them at the end of the season and they were perfect. So comfy I didn't even know I had it on, sits high on the back and doesn't bang into small of back, low profile, can easily fit my water bottle in and a change of shirt/spare pair of gloves. Yay no more annoying bulky water bottle and other stuff in the pockets of my jacket! Great smooth profile not likely to get caught at the back on the lifts. Everything I needed in functionality and the quality is gobsmacking for the price, I expected them to be more flimsy for the price, they are surprisingly solid. I suddenly noticed other people with them on the slopes as well. Great find, might even go back and get the 7 litre one as well. After doing all the research, I think this is preferable to buying an expensive camelbak which then has not enough space for spare clothes etc...
Very good size for everyday use
This super light weight bag is worth every cent! Perfect for what I needed, I just can't believe how good it is, I recommend this for anyone travelling or going on a one day hike, or even just going for a run, perfect bag!
