I bought a Palm Lite Ultra sleeping bag to use in warmer weather with an ultralight setup... quoted weight is 700g (inc sack), it's even stamped on the bag itself... in reality it's almost exactly on 800g.. might not seem like a big deal, but when you're trying to trade off warmth vs weight, 800g starts to make this bag look like a pretty poor choice... 1kg gets you something much, much warmer. I have hiking gear from many brands and nothing else has anywhere near this amount of inaccuracy in specs.

I've spent many nights outside, in a range of bags. The Palm Passport is pretty good value. I was comfortable down to -1c. I was camped on the snow in a double wall tent, only wearing a thin baselayer, thin socks and a beanie. To be warm with this bag at -5c you would probably need mid-weight layers - but you'd need this for most similarly rated bags at that temp anyway. The bag is relatively lightweight as synthetic bags go, and it is probably one of the most compressible synthetic bags on the market. For these reasons, including lower price - it gets a thumbs up from me!

Recently purchased the roman palm iv due to it's small size when packed. Turns out it's very narrow at the bottom so you need to turn with the bag, but can't due to large hood (a pro in really low temps, i'm sure). Double zips at the bottom make undoing and doing up difficult and don't, i repeat don't buy these as a zip together pair. Absolutely shocking design which has the zip in the centre so you can't get in or out without disturbing the other person and someone always ends up laying on the zip, which is really really uncomfortable. Love the Roman camping mats, but would never buy another sleeping bag after this one!
Small size when packed
Badly made, poor zip design for single and when paired

Easy to pack in stuff bag and very compact when compression straps are used.
Rated for 10 degrees plus which is a fair assesment. A nice comfortable bag for warm weather. Can go to 5 degrees but not recommended. I regret not getting the better rated palm IV instead (rated to 5 degrees) which would have been much more versalitle.
Compact, lightweight. Side and bottom zips work well, hood works well
Really only good for summer camping or caravan use.

Despite being in a protected enviroment (Hiking hut), sleeping on a 4 season themal mat, on an evening where the minimum did get below +5C (typical metro west australian mild late spring evening), 3 hikers using Roman Palm Passport all complained of getting cold. So far the supplier doesn't want to know. I'm still waiting for comments from the manufactor, however I've been warned to not expect much.
Lite, Well priced, Full lenght
Failed its season rating - '3-4 seasons' (bags marked -5C)
Given the very mild conditions in which it failed its difficult to rely on the product. You don't what to get caught out cold.

Sure it's cheap, but you get what you pay or....I don't know where they get their ratings from but I'm sure the are not checked by any authority!

Save your money! Cheap [censored word removed] made in China! Over-rated Temperature!
Initially the price!
Just about evcerything but the price...

I bought a Roman Palm Sleeping bag and it fell apart after only a few uses!!The zipper just fell to pieces...It's not as warm as they say it is..and as for the size...I ordered it online..the picture was of a hand holding the sleeping bag...I was shocked when I received the bag....it was so much bigger than what they advertise it to be!!
It was cheap.
Eveything! see above!
