Fireside 3 — Primaloft® Cross Core Ultra + Aerogel / Comfort −5°C
Your pack, your mat and your cold-weather layers are already built to a standard. The Fireside 3 is the sleep half of that system — comfort rated to −5°C, extreme to −12°C, 1,520 grams, packed down to 23 × 28 cm. Insulated with Primaloft's Hi Loft Cross Core Ultra with Aerogel, the same insulation class SORD runs through the MACWO range.
✕ A Camping Bag Solves A Different Problem
Retail bags are engineered around one assumption — a still body, a dry night, and all the time in the world to get in and out. The Fireside 3 is built around the opposite set. Bonded 20K laminate through the foot box and hood, because those are the two ends that meet wet ground and wet air. A centre zip on non-locking sliders, because you may need to be out of it and standing in seconds. Cross Core Ultra with Aerogel, because the bag gets crushed into a pack every morning and still has to loft by last light. Those aren't the decisions an outdoor retail brand makes.
◈ Construction — Shell To Core
Outer shell: 50D nylon with DWR. Inner: 20D nylon with thermal-reflective properties, bouncing radiated body heat back at you rather than letting it pass into the shell. Between them, Primaloft® Hi Loft Cross Core Ultra with Aerogel — a synthetic that holds most of its loft when damp, where down clumps and stops insulating altogether. Foot box and head area step up to a 3-layer bonded waterproof/breathable laminate at 20K waterproof, 20K MVP.
◉ Field Features
| ◉ |
Centre Zip — Fast Entry, Faster Exit Centre zip design with YKK non-locking dual sliders. If you need to be out of the bag and on your feet, you're not fighting a locking slider in the dark. |
| ⚙ |
Large Inner Zip Baffle A generous internal baffle runs the length of the zip, killing the cold line that a centre zip would otherwise open straight down your chest. |
| ✦ |
Bonded Laminate Foot Box & Hood 3-layer bonded waterproof/breathable fabric at the two points that meet the ground and the weather — 20K waterproof, 20K MVP breathability. The loft stays dry where bags usually fail. |
| ▣ |
Contoured Hood, Drawcord Adjusted Shaped hood cinches down with a drawstring to seal heat around the head — the single biggest heat-loss point once the temperature drops. |
| ◈ |
Ample Shoulder Room 80 cm at the shoulder tapering to 55 cm at the feet — enough width to sleep on your side or wear a layer inside without compressing the loft. |
| ▧ |
Compresses To 23 × 28 cm Ships with its stuff sack. A −5°C comfort bag that packs to the size of a section radio is the whole point of Cross Core Ultra. |
⬡ Build The Sleep System
A bag alone doesn't stop conduction — the cold deck pulls heat straight through crushed insulation underneath you. Pair the Fireside 3 with the Straight Mat Insulated to put a thermal barrier between your core and the ground, and add MACWO Booties as a rest layer so your feet aren't the thing that wakes you. In warm, wet country the Lightweight Hammock gets you off the deck entirely.
