[Wanted] Backpacking backpack, trekking poles, and more.

My SO and I are beginning to buy gear and to get into backpacking. Currently I have a tent, knife, and headlamp. I am in need of basically everything else.

I am 6'4, 280lbs, so I will need things that will definitely fit me. She is 5'2 and should fit into most.

Good condition or better please. Any tips are appreciated as well.

I am wanting to purchase the following:

Backpack (x2, male and female)

Sleeping Bag If very slightly used (x2, male and female)

Trekking Poles (x2, male and female)

Sleeping pad (x2, male and female)

Axe or Machete

I am pretty open in terms of brands, and most of the camping/backpacking will be done in Arkansas/Oklahoma/Missouri, so the temperature will be between 40 and 95 at any given time.

Thank you for taking the time to read this
