I purchased these about 18 months and have worn these a dozen times and carried them without wearing them just as many.
First of all these are over trousers, not pants –why does a British company call trousers pants? This is not a dig at Americans as they would use the term pants because that is their word for trousers, our word is trousers – these are over-trousers not pants!
The fabric used is a 79g/m2 2.5 layer 40 dernier nylon with microporous Entrant DT coating and an internal mesh print. The over-trousers are waterproof to a minimum of 10,000 mm hydrostatic head and breathability at 8,000g/m2/24hrs.
This suggests to me to be a waterproof material with reasonable breathability. For comparison a highly breathable fabric such as eVent has a figure of 15,000g/m2/24hrs.
The Atomic trousers weigh 168g in medium size and my pair are black with an elasticated waist and adjustable draw-cord. They have an active cut with high lift crouch and articulated knees.
With a half length zip, they are relatively easy to take on and off. An ideal solution would be ¾ length, but this would add weight to the trousers. There are press stud adjustable ankles and a stuff sack is provided.
Reasons for purchasing
I was looking for as light as possible over trousers and at the weight of 168g (measured by me) they are same of the lightest available. As I often find that I carry over trousers as much as wearing them this was an important consideration. The price of £60 seemed a good price for the specification.
My experience with the Atomic DT over-trousers
These take up very little room in my pack and weigh next to nothing. They are pretty easy to get on and off and are waterproof and easy to adjust.
The biggest issue is they are not that breathable. I found that there has been quite a lot of condensation inside them on a number of occasions particularly around the waist area, which is uncomfortable. There is no way of really venting the trousers.
Whilst these are light and pack up small, they are not in my experience that breathable and I feel that there is an unacceptable level of condensation, when you are working hard in these. I will look to replace these in the spring with an eVent product. For the winter, I am awaiting a pair of trousers from Cioch which are being made for me and therefore I will not require over-trousers for the coming winter period.
As a final postscript to this, I have been unable to find these over-trousers since my two week trip to Scotland, and it would seem that I left these at a campsite at the end of the trip – so I have to replace anyway !!
Overall rating : 3/5
Price: £90 RRP – can be found for £55 on-line.
What I like: weight, pack size, fit and price.
What I don’t like: condensation, no venting options.
What I would recommend it for: 3 season lightweight backpacking where you are going to carry the over-trousers more than wear.
