The Montane Minimus Smock is an incredibly lightweight pullover style, waterproof breathable hardshell weighing just 5.7 ounces in a size XL. Made out of 15 and 40 denier Pertex Shield+, the Minimus Smock is so lightweight that it feels like you are wearing a wind shirt, although it can serve double duty as a waterproof, breathable rain shell if you are willing to forego some of the added features of a fully featured technical rain jacket in exchange for weight and packed size savings.
For example, the Minimus Smock doesn’t have a hood brim or any way to tighten the fit of the hood around the face or back of the head, it doesn’t have a drop tail, and lacks adjustable wrist cuffs. In all three of these cases, elasticized hems around the face, the waist, and wrists personalize the fit, without complicating the garment or weighing it down.
The most noticeable differences between the Minimus Smock and other technical hardshell jackets are the front kangaroo pocket and snorkel style hood. The front pocket is very handy for storing items that must be frequently accessed such as a waterproof map and compass and is large enough to carry a fleece hat or glove liners. It’s mesh-backed and can be opened to vent the Minimus, but will make items stored in it damp from sweat if the waterproof zipper needs to be closed due to rain.
The Minimus also has a snorkel style hood with a high neck that provides excellent face protection in cold wind, with a soft fabric chin guard over the zipper to protect your face. In wind-blown rain, you do need to wear a billed cap to keep the rain out of your eyes (or off your glasses), but chances are you’re carrying a hat like this already for three-season use.
The shell material of the Minimus Smock is very thin and really only suitable for hiking across open ground or well-brushed trails where it is unlikely to be torn by protruding shrubbery or thorns. Further, while the Smock is exceptionally breathable at 25,000 MVTR (including micro-taped seams to increase the breathable surface), you shouldn’t expect this garment to keep your base and mid-layer dry if you’re sweating inside while it’s raining and the zippers are closed. It will keep you warm though by creating a thermal envelope to retain your body heat and prevent evaporative cooling by shedding rain.
Sizing for the Minimus Smock runs small like many of Montane’s clothes and getting a good fit can be a bit of a challenge. For example, I wear a size XL Minimus Smock which is somewhat snug when worn over a thin baselayer and 100 weight fleece. In addition to getting proper sleeve length, some care should be taken when selecting a mid-layer to make sure it is not longer than the Smock torso, lest it peak below the Smock’s lower hem and absorb rainwater dripping off the garment.
The Montane Minimus Smock is an extremely lightweight waterproof, breathable rain shell fashioned like a wind shirt that can serve both functions interchangeably. Though lacking in features commonly found on heavier technical rain shells like a hood brim, wire peak, wrist cuffs, and drop tail the Minimus Smock is ideally suited for fast and light hiking and adventure trips where weight and packability are paramount. While I wouldn’t recommend wearing the Smock in climates like Scotland where the wind’s sole aim is to tear the hood off your head, the Montane Minimus Smock is perfectly suitable for hiking on the Appalachian Trail under a forest canopy in more benign weather conditions.
