Dynafit TLT Light Insulation Jacket


Standard heavy winter clothing has virtually no place in the backcountry. Full down jackets and thick three-layer Gore-Tex pants are fantastic when riding a chairlift in harsh conditions, but when you're moving through the mountains under your own power, light insulation and functional breathability is a necessity. Thin and breathable CLO material covers your back, sides, and the bottom of your sleeves, with baffled insulation on the front of the chest and top of the sleeves to keep you warm no matter how hard the wind is gusting. Two big chest pockets are easy to open with gloves and large enough for skins and a candybar (or four). Don't suffer in a muggy, over-insulated puffy, and don't waste the day stopping to shed layers. With the Dynafit TLT Light Insulation jacket, you'll have the freedom to comfortably move non-stop in even the coldest conditions.

  • Seams and insulated panels stretch and flex smoothly, moving with you and giving you freedom of mobility while still giving you a slim, comfortable fit.
  • Dynafil synthetic insulation keeps you warm and feels like down without clumping and losing its loft when wet.
  • Elastic hem and cuffs are comfortable and seal warmth in without being too tight or restrictive.
  • Perforated CLO padding breathes and vents heat where you exert the most heat.
  • Large front pockets can stow most skins.

Questions & Reviews

Question from Jimbo
How do they run for size?
I where a large shell that is a bit large to accommodate a couple layers underneath.
Answer from jbo
Hi Jimbo, they are fairly true to size. I am always a Dynafit medium and this has a slim fit in the medium, but I can get it over most of my other jackets to use as an outer layer. If you're a large, a large would work great as a layering piece.
Answer from Niko M
Hi Jimbo,
This jacket runs true to size. It would make from a great layer underneath a shell! If you have any further questions feel free to reach out at

Robb (used product a few times)
Perfect for skiing up hill - not too warm. Used it under a shell to ski down - worked great. Plan on using it for local skimo races and use pockets to hold skins. Nicely made and designed.

Used this jacket about a dozen times.
It has a minimal design, without using flimsy/minimal materials.
I have a similar weight puffy from Enlightened Equipment that is made from gossamer fabrics that will never stand up to abrasion like this Dynafit jacket will.
No extra material is wasted on the back and waist, where your pack and belt will be.
No hood means it layers well under a shell.
Napolean style make sense when wearing a pack belt, and are easier to access when this jacket is layered under a shell.
