Not strictly for riding, the Stretch Venture is part of TNF's Flight series and is designed for multisport use.
Its lightweight and stuffable size makes it an easy choice for slotting into a CamelBak, too. It's made from HyVent DT, which is a little less breathable than Gore- Tex, but is just as waterproof - and at a lower price.
With a bit of stretchiness in the material, it moves with you for non-restrictive off-the-saddle manoeuvres. Inside, the seams are all neatly taped and there are storm flaps covering the non-waterproof zips. Two mesh-lined side pockets aid ventilation and there's no rear pocket, which isn't a bad thing if you're hauling a rucksack.
A slightly fitted cut leaves room for layers without being too flappy in the wind. Sleeves and tail are a good length but the longish front can bunch up when leaning forward. There are plenty of reflective strips, and yes, thankfully it's available in colours other than white - which is totally unsuitable for muddy rides. The hood's not needed on the bike but it's darn useful in a wet trail centre car park...
