My Buying Guides on Gregory Nano 18 How To Drink Water
My First Impressions
When I first used the Gregory Nano 18, I wanted a simple way to stay hydrated without stopping too often. My main goal was to figure out how to drink water comfortably while hiking, commuting, or traveling with this pack. I found that the bag is compact, lightweight, and easy to manage, which makes hydration access important.
How I Drink Water with the Gregory Nano 18
My easiest method is using a hydration reservoir. I place the bladder inside the main compartment, route the tube through the drinking port, and keep it clipped near the shoulder strap. This lets me sip water without taking the pack off. If I am carrying a water bottle instead, I keep it in the side pocket for quick access.
What I Look for in Hydration Setup
I always check whether the reservoir fits properly before I leave. I also make sure the hose is long enough to reach my mouth comfortably. For me, a good hydration setup means:
- Easy access to water
- No leaking
- Comfortable tube placement
- Enough space left for my other items
My Preferred Water Carry Options
I usually choose between two options:
- Hydration bladder: Best for hands-free drinking on longer walks
- Water bottle: Best for short trips and easy refills
In my experience, the hydration bladder works better when I want to keep moving. The bottle works better when I want something simple and easy to refill.
Comfort and Convenience
I like that the Gregory Nano 18 stays comfortable even when I add a water system. I make sure not to overpack it, because that can make the pack feel bulky. I also keep the drinking tube positioned so it does not swing around while I walk.
