REI's Backpacking Tips for Beginners is a good place to start.

https://www.rei.com/learn/expert-advice/backpacking-beginners.html

You'll notice the first section is "Find an Experienced Partner". While this sub and others can give you a lot of advice, it's not a substitute for a partner who knows what they're doing. That doesn't mean you can't just go out and "wing it"... if you do, don't bite off more than you can chew. Better to take a few shorter overnights just to get used to things before heading out into the backcountry and having an epic. And I think you need a permits for Yos/Mammoth, so better look into that.

The REI list discusses shared gear and personal gear. Most likely an experienced partner is going to already own a tent, stove, cookware... but if it's just two of you with no gear, you'll have to pick up both shared and personal gear. How you want to split the cost is up to you.

The checklists are nice... but before you go out and buy everything on the list, make sure you will actually need them. Start with the basics; tent, bag, pad, pack, headlamp, FAK, maps & compass, stove, pot, utensils, shoes and clothing... and then go from there.

Here's the REI backpacking checklist:

https://www.rei.com/learn/expert-advice/backpacking-checklist.html

It's comprehensive, but remember you don't need everything on the list. It's pretty common for a beginner to go out and spend way too much money, and then start leaving stuff home as they find they don't need it on the trail.

REI is a great place to spend (a lot of) money. They've got very nice gear, and a great return policy if the gear doesn't work for you... but you'll pay full retail if you just walk in and buy the gear. With a membership, all full price items return 10% to you at the end of the year so it's not too bad, and they have seasonal 20% off coupons which do help. It's a good place to pick up a pack since they can help getting you one that fits, which goes a long way to a comfortable hike. Ditto with shoes, and you can try out mattress pads and see what's comfortable for you.

You can buy other things elsewhere like Amazon... but it's recommended that you go to a gear shop to try on packs (and buy it there to support the store).

Here are a few recommendations:

Pack - Gregory and Osprey are often recommended. For a beginner, 50L-60L is a good size. Don't get a 70L pack, you'll just end up bringing more gear than you need. Try the pack on, load it up with weights, and make sure it fits and carries well. Sometimes the REI packs will fit you better than others... if that's the case get the REI (and save a few bucks).

Tent - Huge range of products here. The Lynx is a decent starter tent for the cost. It'll probably last a few years, and by then hopefully you'll have more money and more experience and get something you like better.

Sleeping bag - If you can afford a down bag, that's great, they're lighter and pack smaller than synthetic bags. The Kelty Cosmic 20 is a good bag for the price.


Pad - Look at the basic inflatables (keep in mind the R-value if you're thinking of going later in the season) like the Thermarest ProLite. Some stick with foam pads like the Thermarest Z Lite pad to save money. Try them out and see what you like.

Stove - The MSR PocketRocket is ol' reliable. Lot of people have them, but the new MSR PocketRocket 2 is more compact and lighter. There are some cheap (< $15) stoves on Amazon, the Etekcity and BRS 3000T... people have been using them but they're small and more suited to people who are just boiling water for dehydrated meals rather than those who actually cook.

Cookset - Don't spend money on a 12 piece cookset...they're cool, but at some point you'll probably figure out you only need a shared pot and a mug for each person. And maybe a small fry pan. Depends on what you want to eat out there. Anodized aluminum is light and sturdy, but more expensive than other options. Titanium is super light, but doesn't disperse heat well so it's great for boiling water, but not so much for cooking non-liquid meals. Stainless steel is heavy but will last many years.

Spork - so many sporks out there... long handled spoons work better for getting food from the bottom of a packet.

Headlamp - Get a decent headlamp. Black Diamond Spot is a nice one, Petzl makes some nice ones as well.

Good luck!

My standard good-but-reasonably cheap sleeping bag recommendation is the Kelty Cosmic 20. There are obviously better sleeping bags out there by just about any single metric, but it's a pretty good compromise of performance, cost, quality, and size.

It would be amazing if you could throw your gear list into a website like www.LighterPack.com. This is the primary tool we use to trim down kits.

Otherwise - tell us more about your wants/needs/restrictions...
What is your budget?

1. Are you shopping in the USA or abroad? Online or local shops?
   
2. What low temps do you expect to use the sleeping bag/pad?
   
3. Have you considered a quilt? Or desire a traditional mummy bag?
   
4. Do you generally sleep warm or cold?
   
5. I prefer down insulation for backpacking, do you have any problems with down?
   
6. 3-person tent sound right?

I wouldn't trust it without seeing reviews.
