While many bag companies try to sell you on an endless list of features you'll never use, Killspencer delivers the one thing you most certainly can't live without: space. The company has taken its daypack design and made it even roomier for those of you who want a good dose of luxury without going overboard with all the miscellaneous bells and whistles. What you do get is a meticulously constructed bag made from grainy leather and suede with more than enough room for all your essentials and then some.
