The Montane Prism is a lightweight synthetic gilet that still offers a good level of warmth. It only weighs 247g in a men’s large and it packs away into its own pocket to create a small package that could double up as a pillow, so it’s an ideal campsite companion. The Prism uses Primaloft’s Eco insulation which is made from recycled fibres and is warm, breathable and quick-drying as well as light and compressible.
The jacket’s outer shell is Pertex Microlight ripstop fabric, which is windproof, fast drying and should withstand any encounters with brambles or snagging branches. It’s also treated with a DWR (durable water repellent) so it should resist light showers, as long as the jacket is kept clean and occasionally re-treated – Montane recommends using Nikwax Tech Wash for this. The jacket’s inner lining is made from a fabric called PEAQ Synthetic which will help wick away any perspiration, keeping you comfortable.
The main YKK zip is anti-snag and has a lock out pull that will stop it from coming undone on its own. It’s backed by a small baffle to eliminate any cold spots. There’s a protective shroud at the collar to stop the zip digging into the neck. The collar is relatively high yet not at all restrictive and there are two fleece patches at the chin, either side of the zip, to make it extra comfy. I would have liked it to be fully fleece lined, but a small lining is better than none at all.
The Prism is a snug fit with a drop cut tail to cover the lower back for added protection from the cold. The hem has a draw cord with glove-friendly adjusters on either side to get the fit just right, and the armholes hen has a draw cord with glove-friendly adjusters on either side to get the fit just right, and the armholes have an elasticated edging to again keep the heat loss to a minimum. There are two side pockets that are both large enough to house a folded map. As mentioned one of these doubles as a stuff sack for the gilet with a reversible zip, but I would have liked them to be fleece lined for added warmth and comfort.
Montane Prism Vest Verdict
A good example of a synthetic gilet.
