Unboxing and First Impressions
The Exped Down Mat Lite 5 arrived, a medium-sized sleeping mat promising four-season comfort. The packaging highlighted its construction: a black, durable material filled with duck down, specifically in the middle chambers. Initial inspection revealed a surprisingly bulky package, but that's understandable given the focus on warmth.
A closer look showed horizontal tubing, reinforcing the mat's structure. However, upon holding it up to sunlight, the down fill seemed less substantial than expected, raising a minor concern about its stated warmth rating. The mat's weight, at 620 grams (21.9 ounces), felt manageable, though it certainly isn't ultralight.
Features and Specifications
The mat boasts a comfort rating down to -12°C (10.4°F), although that felt optimistic. It features a built-in pump-sack design, a safety valve preventing air leakage, and a foam layer at both ends to protect from condensation. An anti-slip fabric is included on the top but might still be slightly slippery.

The mat itself is 183cm (72 inches) long and 52cm (20.5 inches) wide, and packs down to 26cm x 13cm (10.2 inches x 5.1 inches). Filling the mat with air was surprisingly quick thanks to the included pump-sack. Its quality down insulation (75 grams, 2.6 ounces) offers a 700 fill power, and it’s treated for moisture repellency.
Field Test and Performance
Despite initial concerns, the Exped Down Mat Lite 5 delivered surprising warmth during a night with temperatures close to 0°C (32°F) and a chilly wind. Though I did wake up a few times, the comfort level was significantly better than a previously used, firmer inflatable mat.

The mat's honeycomb-style construction might contribute to its softness and added durability. The back especially felt warmer than expected, suggesting effective heat retention. The mat did lose some air overnight, as many air mattresses do; this is not an issue specific to this mat.

Final Verdict
The Exped Down Mat Lite 5 exceeded expectations, providing unexpected warmth and comfort, especially considering the relatively lightweight and compact design. While the initial visual inspection of the down fill was less than impressive, the performance in cold conditions proves its effectiveness.

The included pump-sack is a big plus, speeding up inflation significantly, and the anti-slip top layer, though not perfect, is a nice addition. The mat's bulkiness might be a drawback for ultralight backpackers but this trade off for comfort and warmth is certainly worthwhile.
