Most runners already have a lot of strength in their legs; it would be easier on you to make your legs carry your water. The thigh holster keeps your water near and easy to reach and is perfect for holding larger sized bottles. This carrier is ideal for those not wanting to carry their water in their hand or on their back, and it fits snug on your thigh without slipping or shifting around. These holsters are best for shorter runs that don’t require massive amounts of intake, of course, you can always buy two.
