+ Mammut describes the Trovat jacket as 'an ideal companion during the cold season'. Having obtained this jacket during a brief summer heatwave, we had to wait some time before properly road-testing it. In fact, it's so effective at retaining heat and keeping the rain out that only by climbing a Cairngorm ridge in sub-zero conditions might you really take the jackets to the limits of what it can offer the walker. The jacket fits well and hangs nicely on the body. It doesn't cling to your skin even when wet, and is easy to put on with no fiddly zips or flaps to tuck out of the way. Insulation and waterproofing are the Trovat jacket's real strengths. It's very warm, to the point that you can easily overdo the layers beneath it, even down to near freezing conditions if you're generating a bit of heat and walking vigorously. On crisp winter moorland walks just a light baselayer was needed underneath. The chin protector and hood work well - never too tight and easy to adjust even in high winds. The hood is not 'grown on ' - it has a zip enabling removal - but this remains secure and drip-proof in heavy rain. The two-layer Gore-Tex offers reliable waterproofing and the jacket is also exceptionally windproof, even in force 10 gales along the Severn estuary, when the hail was almost horizontal. Durable and robust velcro cuffs are easy to strap over gloves.
- Although there are plenty of pockets, including two hip pockets and two chest pockets, none are large enough for an OS map and the two chest pockets are better placed for a phone or GPS unit. The jacket's two internal net pockets are also puzzling - again, they are too small for maps but too loose for items such as gloves, hat or a water bottle, which tend to wobble around or fall out. At 850g for a men's large, the jacket is also fairly hefty, even for a winter waterproof. In our previous winter jackets round-up, only the Paramo Alta III and Keela Munro are of comparable weight.
VERDICT: Despite a few minor quibbles, for keeping warm and dry, this is the best jacket we've tested for some time. Mark Rowe
