MARMOT Mica jacket, £99, www.marmot.eu
It’s weight and compactability that makes this jacket special — at just 200g it feels and stuffs into a pocket like a windcheater, but it’s completely waterproof, with fully-taped seams. It’s also got an adjustable peaked hood, elasticated hem adjuster, Velcro adjustable cuffs and two zippered handwarmer pockets.
The fit’s more ‘athlete’ than ‘tellytubby’ and the sleeves (with reflective tabs) are nicely designed so they don’t ride up when you’re hunched over your bars, though a slightly longer drop-tail would make it perfect. A great choice not just for commuting, but touring and other pursuits. S-XL.
PROS carry anywhere, highly breathable
CONS slim fit won't suit everyone
