This may seem like a far-off comparison, but I'm hoping someone here can humor me. I'm undecided on keeping the daylight backpack I ordered because I miss the compartments in my Synapse 25.
Looking at the dimensions, the S19 seems similar in size (l x w) to the daylight and keeping it as light and squishy as possible, the halcyon material is probably the best comparison.
If anyone has both bags, can you post some pictures of each and include one with the same stuff packed into each bag as well? I know the synapses can bulge a bit, but if lightly packed with the same load, I'm curious how much bigger it looks over the daylight.
Unfortunately, there are no halcyon S19's in stock at the moment or I would buy one to try out this comparison myself.
