Fill density in sewn through items is a balance between calculated loft and chamber width. As standard, our sweater fill density is optimized for static use, trying to maximize the warmth to weight ratio. There are cases where down garments get flexed into semi-active use where a higher density might be ideal. Examples might be someone who has an extensive camp set up in inclement weather, or someone who might end up sitting out in some precipitation, or even for folks who might want to flex a down garment into hiking use on cold morning or whatever. It should be noted that hiking in down gear is generally not a great idea since the properties of that kind of wear just doesn’t fit well with activity and wearing down gear under backpack straps is almost always a very bad idea. However, there might be room to flex these garments into these uses a little bit, here and there.
For folks who want to flex their down gear into some of these, or similar usage, higher chamber density would be helpful to maintain control when the fill gets a little compromised by moisture. We typically accommodate this by bumping the chamber width down to the next level. So a 1.5 would get the 5″ width of the 1.1 instead of the normal 6″. For any casual wear or semi-active garment, I would recommend this. Technically, this could be bumped down two levels for even higher density in compromising conditions.
To place an order with this mod, all you need to do is go to the page of the sweater with the fill level you want and use the notes box to request that we drop with chamber width down for higher density. Then use the add-on page to add $15 to the cart for the increased labor.
