Diesel Slim Jeans Regular Waist D-ASKAR, Medium blue, Zip fly

Jeans

$347as of Jul 14, 2026. Check the current price at Diesel

The verdict

A slim medium-blue jean priced at the high end of Diesel's range; buy it for the fit, not for exceptional value.

Fit

Regular waist, slim through the leg; expect a closer fit than the relaxed or bootcut styles but more room than the Sleenker skinny line.

Quality

At $347, this is near the top of what Diesel charges for jeans, but nothing here suggests extra construction beyond the standard medium-blue wash and zip fly.

Price check

This price is mostly brand tax; a similar slim medium-blue jean at far less exists elsewhere, so pay it only if the Diesel name specifically matters to you.

Best for

A committed Diesel shopper who wants the slim fit in a versatile medium-blue wash.

Care

Wash cold and infrequently to keep the medium-blue color from fading unevenly.

What owners report about Diesel jeans

Owners describe Diesel's denim as sturdily built: sturdy stitching, heavy-duty zippers, and a cotton-elastane blend that keeps pairs flexible rather than flimsy. On owner forums, people report pairs still fitting well and holding their wash after five to six years of regular wear, describing the jeans as lighter-weight and more comfortable than expected for the style. The cuts are snug through the seat and thigh with room to move rather than a roomy, relaxed fit.

Strengths: Reviewers consistently point to sturdy stitching, heavy-duty zippers, and a fabric blend that stays flexible rather than stiff or flimsy.
Watch out for: The fit runs snug and style-driven rather than roomy, and owners say sizing needs to be chosen carefully to get the cut right.
Sizing: Most owners report the line running true to size across fits from relaxed to skinny, but the cut is snug through the seat and thigh rather than generous.
