Hiking backpack…What is the best bag for me to buy?
I want to go on day hikes this summer. I need a backpack just for the essentials…water bottles, lunch, sunscreen. What would be a good backpack to buy, thats light and would cause me to sweat even more on a hot day.
well if your going backpacking for day and night I would get a full blown out pack..
if your just going for a day
a day pack is GREAT
I would try REI brand it’s not the most costly but their brand is GREAT!
I have the full back pack i go for days to camp.. some even have detatchable day packs so you can leave your pack at camp!
hope that helps good luck!
