Thule Men's Capstone 22L Day Hiking Backpack, Small/Medium Fit, Poseidon/Light Poseidon

This mid-size day pack from Thule features a waistbelt stabilization system with easily-accessible stash pockets, organization inside for hiking gear and food (or books and a laptop), and it's even hydration-compatible with a reservoir sleeve and drink-tube exit port (reservoir sold separately). Whether your next summit is on a snow-capped peak or in a beige-painted conference room, this bag is the best way to make sure everything you need gets there with you.

A tensioned mesh back panel provides unparalleled breathability, keeping you cool and ventilated where the bag rests against your back. The hip belt is adjustable and works with VersaClick accessories to attach whatever you need to carry--bottles, coils of rope, trekking poles, and more. Additionally, there are attachment points to either side of the back of the bag for hooking carabiners and lashing items that won't fit inside the bag. A small zippered pocket at the top of the bag handles your small items, like headphones, snacks, sunglasses, etc., and to top it all off there's a high-visibility removable rain cover to make sure your gear stays dry as possible.
