G'day Renea,

The Pillow Lock system is actually attached to the sea to summit mattresses. The fabric of the pillow base itself adheres to the pillow lock tabs on the mattress and stops it sliding around. So yes, the pillow is compatible with a mattress that has pillow lock.

G'day Summa,

The Sea to Summit Pillow lock system is honestly great. As long as your Ether Light mattress came with the stick on patches you'll find out just how great the system is. It works using a similar concept to velcro, but it's super soft and will stop your pillow sliding side to side or up and down.

G'day Pete,

You're correct mate, this model is what Sea to Summit call Premium. I'll ask our web team to update the naming of these. Just to break it down a bit, they make four models in both an Ultralight and Premium finish. The Traveller, Deluxe, Large and Regular.

G'day Jen,

The Sea to Summit Aeros Pillow comes with a valve that allows either inflate or deflate only, which makes it really easy to blow up. Your son shouldn't need a pump to inflate his pillow. 

G'day Corey,

Sorry about this. Are you able to give us a call on 1300 914 007 as we'll need to talk through where the issue is arising from?

The same principle can be applied here Gareth, a pillow filled with foam will insulate better than an air filled one, but given you are using it within a warm environment i.e. on top of your may and inside your sleeping bag, then I would personally place a bigger focus on weight and packed size.

This being said, this Aeros pillow with the brushed polyester cover will offer some insulation over an above the ultralight models without the cover, so it's a good balance of all things we've mentioned here.
