Trestles Elite Eco 20° Women’s

I would steer clear of Amazon unless you find something from a big-name outdoor brand on there (marmot, big Agnes, mountain hardwear, Nemo, to name a few). A no-name Chinese brand bag is probably not going to meet quality or temperature expectations. Your local REI would be a good resource. Their house branded stuff is trustworthy. SierraTrading (TJmaxx for outdoor gear) usually has a decent selection of name brand options. I have a 20° marmot bag from there that was $80. Buy a bag that’s at least 10° colder than the temperatures you expect to encounter. Caveat is that like most camping equipment, no modern sleeping bag is going to be truly BIFL, they are wear items at the end of the day. In a hammock, the compression of the bag underneath your weight will always hinder the insulation ability. This can be mitigated with a foam or air-filled sleeping pad. You may have to experiment to find one that fits your hammock, fits your dry bag, and keeps you warm enough, so I would say this is something you could grab on Amazon for ~$20. Edit: didn’t register your parts about the under quilt but yeah it’s just a matter of spending money and experimenting, unfortunately

I got a long bag for a great price. I stuff extra clothes in the bottom to take up the extra space because my feet end up cold if I don’t. I learned my lesson and bought a regular bag when I needed a colder bag.

That’s why I bought a shorter bag when I needed a bag with a lower temperature rating. It’s much better.

Used Marmot Treasles Elite Eco. You can find these used on eBay and REI ReSupply for around $50 or less often.

Naturehike Mongar 2p. If you really can get a Marmot Limelight for under $150 definitely get that over the Naturehike (DAC aluminum poles and a lifetime warranty are primary reasons). For a bag I would look for a deal on a Marmot Tressles Elite Eco. I have seen the older models on clearance for under $100. These pack down much smaller and weigh far less than traditional synthetic bags. If you can afford a down bag go for. Paria Outdoor Products Thermodown 30 or 15f. Otherwise if you are with used try to find a quality down sleeping bag. Cots under $75 go with a Naturehike, iClimb or Kingcamp cot with aluminum poles and legs. Aluminum cots pack down way smaller and weigh significantly less than steel. For the sleeping pad I would recommend a knockoff of the Exped MegaMat. Semi inflating mats are way higher R value than the junk Intex and Coleman air mattresses and way more comfortable. A budget alternative to the MegaMat would be th Stoic Cloud or Cloud Lux or the Hikenture semi inflating mat. These are 3-5" thick and feel like sleeping on a bed at home. Combine them with a cot and it's pure luxury.

Love my Marmot Trestles!

Marmot Trestles line are good deals on good bags. If you’re younger, just get a blue foam pad.

Marmot is a solid brand, like the other commentor said its a personal choice. I would invest in the Marmot down fill bag myself and thats based on the longevity and utility of all my other Marmot purchases.

Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.
