Sea to Summit Aeros Premium Inflatable Traveler Pillow (Lime) $49.99 + Delivery ($0 with Prime/ $59 Spend) @ Amazon AU

I've been looking for an inflatable travel pillow since regular ones take up so much space. This one comes from a reputable travel brand. The ATL is $44, so this is a pretty decent deal considering the RRP is around $65. Do note that this is for the premium version, not the regular "ultralight" version. The premium version is supposedly more comfortable thanks to the materials while only being slightly heavier (79 grams vs 60 grams). You can take an additional $10 off if you got the promo code offer.
