a_hale_photoI’m going to be so real, the REI Helix pad is pretty damn great for a fraction of the cost. You get a 4.9 value, and holds air all night. Bought two recently and it’s been great. Anything else you’ll just get lighter weight
AN0NY_MOU5EI had the same experience trying to get a mattress. Several of them leaked.
aPerson39001C9The REI Helix is terrible uncomfortable. Especially for side sleepers. The Nemo Tensor is much better. I haven’t tried the others.
Beneficial-Side-4201I actually love the REI Helix, especially with a closed-cell foam under it.
_BourbonMy Rapide SL insulated is very comfortable but nowhere close 4r. It might be 2r. Maybe. I just replaced it with the REI helix. 1oz heavier, but even more comfortable and a “true” 4.9r. They retail for $160. Exped 5r is also comfortable, warm, and has a great pump sack - although I suspect they’re getting ready to revamp them in the spring and they’ll be a decent amount more compact and lighter then. But you’ll probably find good Black Friday deals on the current one.
