Reddit mentions of Snugpak Jungle Bag Olive RH Zip

> They seem way more claustrophobic since you cant open the side, you're stuck in except for a slit underneath you

You just lift the side up. You don't have to strap yourself in except in very cold weather, which it doesn't sound like you're planning to do. It's basically a very puffy blanket; the strap is optional.

> Is that Teton bag comfortable in warmer weather?

It's pretty comfortable until you get to really warm weather, like when it's 70+ at night. If you're talking about really hot camping weather, you might also want to consider the Snugpak Jungle Blanket: https://www.amazon.com/SnugPak-Jungle-Blanket-Olive-X-Large/dp/B073C59WR7/ref=pd_bxgy_468_img_3/145-5235641-7127537?_encoding=UTF8&pd_rd_i=B073C59WR7&pd_rd_r=b86c4e0a-5e47-4196-9a40-da95cfaceaf6&pd_rd_w=yh2L9&pd_rd_wg=Quyfa&pf_rd_p=a2006322-0bc0-4db9-a08e-d168c18ce6f0&pf_rd_r=E3N65DB5TXCBZDG6YJNR&psc=1&refRID=E3N65DB5TXCBZDG6YJNR

I've got the Jungle Blanket and it works extremely well for hot weather.
