The Trailpant is a well fitted, lightweight set of running waterproofs. With more durability and features than the Ultra- version these provide a more comfortable fit for extended use. 

Inov8 says:

A versatile, fully-featured waterproof running trouser for men. Designed for really cold, wet conditions, the new TRAILPANT is more waterproof and breathable than its predecessors. It also stretches with the lower body to allow unrestricted running movement.

Inov8's Trailpant Waterproof Overtrouser are a comfortable, durable alternative to the Ultrapant series. They stand up to the challenges of more extended and more regular use as they have a higher denier fabric for smashing your way through the heather in races. The fabric is soft and surprisingly comfortable, especially on long runs. With high levels of waterproofing and breathability these pants are a great option on race day or simply training days on the fells and mountains.

The stretchy fabric is really comfortable to wear in any conditions for as long as you need and does not restrict movement when in full stride like some other pants. The pants also have decent zip height from the ankles making then much easier to get on or take off over trail shoes. The pants pack down into a small pocket when not in use saving vital space for other necessities.

The quietest and most comfortable waterproofs

These pants have the softest and quietest exterior fabric on any waterproof I've tried - yet they still have superb waterproofing. They are so comfortable that they are fine for wearing as trousers (although they won't be quite as breathable). The thick soft waistband is great. The only negative as mentioned by another review is that you cannot pull these on over shoes and boots. Even over trail shoes they struggle to get over. However this means these pants are more tapered and form fitting than other waterproofs (without restricting movement). This means they are more suited for running or fast hiking. For me they are perfect - however if you require a pair that you can easily pull on over boots look elsewhere.

Nice but not for pulling over boots

I thought I might try these as a lighter pair of waterproofs than my old Paclite pair. Nice material and true to size fit, but despite the knee length zip they won’t pull over a pair of Crosshike light boots size 10, so not suitable for me. I thought this might save someone else the same bother. I returned them and UOG refunded promptly as they do.
