LoftTek synthetic down

While synthetic down jackets aren't as insulating as natural down jackets, synthetic down jackets have an advantage and that is they don't lose their loftiness when wet like down jackets do.
The LoftTek Adventure Jacket synthetic down looks and feels like the soft, fluffy undercoating of waterfowls and the best part is that birds were not directly harmed in the making of the jacket.

Compared to regular down, the LoftTek Adventure Jacket "does what it says on the tin" and that is you can get the jacket fully and completely soaked in water without the LoftTek jacket becoming a heavy bag of wet feathers. 

The LoftTek Adventure Jacket synthetic fiber filling is not made of a natural material like cotton, which is a natural hypoallergenic, but it uses siliconized polyester filling which repels allergens and bacteria preventing allergic reactions.

The LofTek synthetic down is hydrophobic down so it repels water via a Durable-water-repellent (DWR) coating applied to it the same way as rain jacket shells. 

The DWR coating is the reason why the LofTek synthetic down is able to maintain loft and retain warmth even when wet. However, DWR does not last forever and does contain flourcarbons or PFCs which are toxic chemicals similar to BPA.
It's unclear whether the LoftTek Adventure Jacket is DWR PFC free but most top outdoor clothing brands including The North Face, Patagonia, Gore-Tex and Arc’teryx use PFC chemical for their DWR coatings.

Speaking of top brands, the LoftTek Adventure Jacket does a good job at rivaling its direct competitor The North Face Thermoball hooded jacket by offering additional features such as underarm zippers, elastic cuffs and thumbholes to prevent the sleeves from rolling up when extending the arms.

The LoftTek Adventure Jacket stitching has a baffle box construction similar to the stitching of duvets so the shell of the LoftTek Adventure Jacket is sewn in stitched pockets which are then stuffed with thinly scattered down.
Compared to other down jackets, the LoftTek down stuffing is minimal and translucent so light can actually pass through the jacket.
If you own a high fill power (900+) down jacket, you won't find the LoftTek jacket as fluffy; but it's worth keeping in mind that the LoftTek jacket is an ultralight synthetic down jacket that weighs only 400 grams and is much more breathable and faster to dry than a natural down jacket after being washed.

As far as temperature range, the LoftTek Adventure Jacket is able to keep its coziness in the damp and cold English weather of February performing well under freezing (approx. -1 Celsius) and humid conditions. 

The fabric material used for the shell is made of 20D ripstop breathable nylon coated with "VitalDry" Durable-water-repellent (DWR) coating, making the jacket durable and water resistant so water literary rolls off the jacket.
Having said this, DWR isn't the same as waterproof but having DWR coated on the shell means it helps the shell shed water and dry faster when wet.
The LoftTek Adventure Jacket zipper pockets are sewed-in behind the down insulation of the jacket, which is protected by 10D ripstop nylon lining fabric.

Even though 20D material is heavier and less breathable than 10D material, it's nice that the LoftTek uses 20D fabric for the shell because it has a higher abrasion resistance and because 20D fabric has a windproofness of 1cfm (Cubic Feet per Minute), which is almost windproof. A regular rain jacket and fleece have a fabric windproofness of 0.6cfm and 195cfm respectively.

In the event that you rip or tear the LoftTek Adventure Jacket, you won't have to worry about losing the filling because the LoftTek down is made of continuous strands of siliconized polyester rather than lose feathers. Check out the new Shadowlight Ultralight.
