Assos tK.607_S5 Bib Knickers $298.95
When tights are overkill, but shorts leave your knees cold, the Assos tK.607_S5 Bib Knickers are the simple solution. Insulated to keep your muscles and joints warm, the tK.607_S5 provide the same plateau of Assos quality as the summer-weight T.607_S5 — only now you get the pinnacle of cool weather protection.
Assos' tK.607_S5 bib knickers use a combination of Assos' exclusive RXQ and stratagonUltra fabrics. The bulk of the construction uses the RXQ insulating fabric which uses a 3D air channel structure. This open structure creates a micro air cushion between the skin and the fabric. And while this creates an insulating layer that's capable of retaining your natural body heat, you won't drown in sweat in the same way that you do with other fabrics. This is because RXQ is a low-density, low-volume fabric, and its breathability keeps your core dry and your temperature regulated. At the abdominal and inner-leg areas, Assos placed its windproof stratagonUltra material. This takes the bite off of chilly winds, which Assos explains, oddly enough, reduces your 'need to pee.'
As impressive as the Assos fabric lineup is, the true Assos signature is its precision fit. Utilizing what Assos calls its Advanced Ergonomic Pattern Design (AEPD) racing cut, the tK.607_S5 benefits from the most thought out designing process in the business. Assos is the first to tell you that high-end materials mean nothing if the cut is bad. That's why it's spent a maddening amount of time on two points of study — how the body is shaped, and how it changes throughout the movements of cycling. Accordingly, the AEPD cut is made for the shape of cycling, not standing (just a little something to remember when you try them on). With the tK.607_S5, the cut greets the contours of your body and adds a slight compression that aids in muscle stabilization. It's worth noting that AEPD achieves this without adding a sensation of pressure. Further along these lines, the leg grippers use a no-pressure elastic. To achieve this gentle grip, Assos integrated them with the fabric of the knickers instead of placing them inside the hem. Altogether, the characteristics of AEPD literally make the knickers 'click' into place for the ultimate in cycling fit.
The tK.607_S5 has been given the Assos exclusive FI.Mille_S5 elastic interface chamois. Now, you've probably heard of CyTech's Elastic Interface Technology, but guess who's engineers spearheaded the project? That's right, it was Assos. Designed to follow the body in motion, the FI.Mille_S5 uses a variable density throughout the chamois to support the regions that need the most support, without impacting the ones that don't. The support focus is primarily placed at the perineal, ischial, and gluteal areas — the points most prone to distress from saddle pressure and compression. With its anatomic design, the FI.Mille creates an abrasion-free support that promotes an increased circulation by protecting nerves like the pudendal. Further along these lines, FI.Mille's waffle texture also works to dissipate any buildup heat. Even more impressive, the insert is road-specific. Assos engineers realize that saddles and saddle positions vary throughout different disciplines of cycling, and the insert's chamois density patterns are mindful of the specific pressures of road cycling.
The Assos tK.607_S5 Bib Knickers are available in the color Black Volkanga and in six sizes from Small to TIR.

What community has to say
NOT SURE I LIKE IT
- Familiarity: I've used it once or twice and have initial impressions
Me: 6'2", 160 lbs, 31 in waist.
Large fits very well.
Pro: impeccable finish, fabric is so soft and plush that my wife thought these were natural fibers (think cashmere), fit is "race-cut" (good for my body shape), warm enough into the 30's
Con: Chamois is giga-thick (think ultra absorbent diaper), calf gripper are not sticky so they ride up.
First purchase from Assos. I expected perfection but got something else. Will update review once I ride with it a few more times.
