A green synthetic-insulation Arc'teryx-style jacket with an embroidered logo, listed in S–XXL. The fit and wear notes below come from reviews of the Atom LT line, not from this listing, so treat them as line-level context. Ask the shopping agent for flat chest, shoulder and sleeve measurements before ordering.

Pros
- · Forum users praise the Atom line's cut and fit
- · Forum users report the lightweight face fabric held up through abrasive use such as pushing through brambles
- · Testers describe the Atom LT as comfortable, with breathable side panels, a soft collar and good temperature regulation for active use
Cons
- · A reviewer noted the hem does not always stay down when worn
- · One 179 cm / ~72 kg tester in size M found the sleeves could be a little longer, so arm length may feel short for taller wearers
Fit notes
Arc'teryx sizing is generally described as trim/fitted, and buyers are commonly advised to size up if layering underneath, for example as a mid-layer under a shell. A 179 cm / ~72 kg tester in M reported the body and length fit perfectly, but sleeves could be longer. This listing offers S–XXL.
Buy if
You want a trim-fitting synthetic mid-layer in green, available in S–XXL, and you or your agent can confirm chest and sleeve measurements against the jacket before it ships.
Skip if
You are tall through the arms and cannot verify sleeve length first, or you need a hem that reliably stays down over active movement.

Buying FAQ
Common questions
Does this jacket run small?⌄
Arc'teryx sizing is generally described as trim/fitted, and the common advice is to size up if you plan to layer underneath. Confirm availability in your size across the listed S–XXL range with the agent.
Will the sleeves be long enough?⌄
A 179 cm / ~72 kg tester wearing size M found the body and length fit well but the sleeves could be a little longer. Taller wearers should check sleeve measurements before ordering.
Is it suited to active use?⌄
Testers describe the Atom LT as comfortable with breathable side panels, a soft collar and good temperature regulation for active use. That is line-level testing, not a measurement of this listing.
Does the hem stay in place?⌄
One reviewer noted the hem does not always stay down when worn, which is worth weighing if you plan to wear it over active movement.
What sizes and colour are listed?⌄
The listing covers S, M, L, XL and XXL in the green colourway with an embroidered logo.
