Generator Alpine Jacket

【Store Manager's Comments】

It's incredibly warm! But it's also lightweight and durable. We highly recommend this to anyone looking for a warm jacket with those qualities. (For details on its durability, please see the face fabric section in the specifications table below.)

The Rab official page claims it's the warmest, lightest, and most packable belay jacket in Rab's history, and it certainly lives up to the hype.
You can feel it warming you up the moment you put it on. As it's a belay jacket, it's also great for simply throwing over your clothes.

This jacket delivers top performance in the worst conditions.

【Sizing】

Rab uses UK sizing. Rab products also come in slim fit or regular fit depending on the model. For slim fit models, I usually choose a UK M, while for regular fit models, I usually choose a UK S.

This Generator Alpine Jacket has a regular fit and is oversized.

For my 170 cm, 68 kg build, a "UK S (JPN M)" is a perfect fit. If you plan to wear it over a thick top, choose a UK M.

※If you plan to throw it over a shell, don't size down and choose your usual size.

Model wearing: Height 190 cm, Size M
