Assos Mille GT Ultraz Winter Jacket S11 EVO Golden Yellow Men's

The Assos Mille GT Ultraz Winter Jacket S11 EVO is the jacket you put on when the thermometer is below zero and you still want to get out of the door. This cycling jacket is made for rides between -8 and +3 degrees and scores 5 out of 5 for both insulation and windproofing, without leaving you moving like a padded doll.

The EVO version is warmer than its predecessor and at the same time less restrictive: small changes to the collar, shoulders and chest give you more freedom of movement on and off the bike.

Assos Mille GT Ultraz Winter Jacket S11 EVO at a glance

• twinDeck front panel: storm-proof AIRBLOCK-EVO.888 with an inner layer of HEATER, a waffle structure that traps warm air and actively wicks moisture away.
• Insulation 5 out of 5: the warmest jacket in the endurance line, made for the coldest rides of the year.
• Windproofing 5 out of 5: cold headwind does not get through, not even on a descent.
• CORE Medium sleeves: thermal layer and 3L softshell in one, so warm arms without extra bulk.
• RX EVO Plus on the back and forearms: keeps the warmth dry and adds breathability and stretch.
• Temperature range -8 to +3 degrees: clearly defined, so you know when to reach for this jacket.
• Triple ramp pockets: your kit stays in place and protected against snow slush and spray.
• Reflective detail on pockets and logos: extra visibility on dark winter days.

Warmth that stays where you need it

The protection starts with the twinDeck construction at the front. Two layers sit on top of each other there: the storm-proof softshell AIRBLOCK-EVO.888 on the outside and HEATER on the inside. That waffle structure traps small chambers of warm air and at the same time draws moisture away from your skin. On the first kilometres of a ride in freezing weather that is the difference between gritting your teeth and simply cycling.

Sleeves without extra bulk

The sleeves are made of CORE Medium, the most insulating fabric in the CORE softshell family. It combines a thermal layer with a 3L softshell in a construction that stays thin. Your arms stay warm and you keep your freedom of movement in the riding position, without the thick layer that often makes winter jackets stiff. The ECO water-repellent treatment keeps light precipitation and spray out.

Moving instead of being packed in

The biggest difference from the previous generation is in the fit. The jacket stays streamlined, so there is no flapping material, but the construction is more elastic and the collar, shoulders and chest have been given a little more room. You notice that when you are breathing hard in the red, when you reach into your back pocket and simply when you stand upright as you stop for a coffee.

Who this jacket is for

This is the jacket for the endurance rider who wants to keep putting in kilometres in January too: steady to hard long rides in the cold, long hours in the saddle, often in low light. Anyone who mainly trains hard at four degrees or above will get too warm in this and is better off looking at the Mille GT Winter Jacket S11 EVO. For persistent rain you combine it with a shell jacket.

Good to know

That much insulation costs breathability: this jacket scores 2 out of 5 there. On short, intensive intervals you can get warm quickly. It is not waterproof, the score is 3 out of 5, so for a day with real rain you take a rain jacket along.

Frequently asked questions about the Assos Mille GT Ultraz Winter Jacket S11 EVO

At what temperatures do I use this cycling jacket?

Assos states -8 to +3 degrees. That is genuine freezing weather through to cold, grey winter days. Above four degrees this jacket becomes too warm for most riders, certainly if you train hard. For those temperatures the Mille GT Winter Jacket S11 EVO is the better choice.

What does twinDeck mean?

twinDeck is a double construction in which an insulating, thermoregulating layer sits under a storm-proof softshell membrane. On the most exposed zones you therefore get two functions in one: protection against wind and precipitation on the outside, holding warmth and wicking moisture on the inside. In this jacket that construction sits on the front panel.

Is this jacket waterproof?

No, waterproofing scores 3 out of 5. The jacket keeps out snow, spray and a shower without trouble, but in hours of rain the water eventually gets through. Pull a shell or rain jacket over it in that case; thanks to the streamlined cut it fits without bunching up.

Can I also wear this jacket at high intensity?

You can, but bear in mind the breathability of 2 out of 5. On intervals or hard climbs you build up heat and moisture. If you mainly ride hard and short, you are better off with a lighter winter jacket or a race fit model. For long, steady winter rides in the cold this jacket is exactly right.

What do I wear underneath in freezing cold?

A long thermal base layer is the logical basis at these temperatures. The HEATER inner layer draws moisture away from your skin, so choose a base layer that does the same instead of cotton. At -8 degrees many riders add a thin mid layer; around freezing point a good base layer is usually enough.
