How to Layer the Eos Down Vest for Cold Weather

Quick Answer

Layer the Eos Men's Down Vest over a breathable baselayer or lightweight fleece, then add a windproof or waterproof shell when conditions demand it.

How to Layer the Eos Down Vest

1. 1. Start with a Breathable Baselayer: Wear a merino wool or synthetic baselayer that wicks moisture. The vest traps heat against your core, so a damp base will make you cold fast. Avoid cotton—it holds sweat and kills insulation.
2. 2. Add a Midlayer (Optional): If temps are below freezing, layer a lightweight fleece or micro-grid jacket over the baselayer. The vest then goes on top to lock in warmth. Common mistake: adding a thick midlayer that compresses the down and reduces loft. Keep the midlayer thin to preserve the vest's loft.
3. 3. Put on the Eos Down Vest: Zip up the vest over your midlayer or baselayer. Adjust the elastic drawcord hem to seal out drafts. The Lycra cuffs and zippered hand pockets stay out of the way when you're active. Check that the vest isn't too tight—if it restricts arm movement, your midlayer is too thick.
4. 4. Top with a Shell for Wind or Wet Conditions: Layer a windbreaker or hardshell over the vest to block wind and light precipitation. The sewn-through construction of the vest means cold air can pass through the stitching, so a shell is essential below freezing or in high winds. A shell also protects the down from moisture, which kills loft.
5. 5. Adjust for Activity Level: When hiking uphill or working hard, unzip the vest or remove it entirely to avoid overheating. Stash it in its stuff sack—it packs down small enough to fit in a daypack. Venting is key: a sweaty down vest loses insulating power until it dries.
