Before You Decide
Confirm the hydration format, the stated 2.5L capacity and the fit adjustment features before choosing an offer. If the whistle, reflective strips or pocket layout matter to your planned use, check those details against the exact vest variant.
Planning Your Carry Setup
Before your first outing, decide what you want in the vest and what you want in the bladder. The pocket layout suggests room for small essentials such as gels, bars and a phone, while the hydration setup is centred on the included 2L bladder. Keeping the load organised before setting off should make it easier to pack the vest in a way that matches your route.
